Term Index (Alphabetical) --- ## Core Concepts Foundational terms that describe a swimming pool and its basic structure. ### Pool Shell **Definition:** The pool shell is the structural concrete body of a swimming pool. It is the load-bearing form, typically made of gunite or shotcrete over steel reinforcement, that holds the water and supports every other component and finish. **Extended Explanation:** The shell is the most important and most durable part of a pool. Every later element, including tile, coping, plumbing, and the interior finish, depends on a sound shell. A well-built shell can last for decades. When a pool ages, it is usually the surfaces and equipment that fail, not the shell. This is why most aging pools are good remodeling candidates: the expensive structural element is still serviceable, and only the surfaces, tile, and equipment need renewal. A shell can develop structural cracks over time, especially with soil movement or poor original construction. These cracks must be repaired before a new interior finish is applied. **Key Characteristics:** - Made of gunite or shotcrete over steel reinforcement - The load-bearing, water-holding structure of the pool - Typically outlasts surfaces and equipment by decades **Practical Application:** When deciding between remodeling and rebuilding a pool, a contractor first assesses the shell. A sound shell points toward a remodel; serious unrepairable structural failure points toward a rebuild. **Adams Pool Solutions Perspective:** We assess the shell before recommending a scope of work, so owners can make an informed remodel-versus-rebuild decision rather than defaulting to the larger job. See our [pool resurfacing service](/services/pool-resurfacing/). **Related Terms:** Gunite, Shotcrete, Structural Crack **Learn More:** - [Pool Resurfacing](/services/pool-resurfacing/) - [Surface Preparation](/services/surface-prep/) --- ### Interior Finish **Definition:** The interior finish is the surface layer that lines a pool's shell, contacts the water and swimmers, and gives the pool its color and texture. Common finishes include plaster, pebble aggregate, and tile. **Extended Explanation:** The interior finish serves two roles: it makes the shell watertight at the surface and it provides the pool's appearance. Because it is in constant contact with water and pool chemicals, it is also the part of the pool that wears out first. Different finish materials have different lifespans and price points. Plaster is the economical baseline; pebble aggregate finishes last far longer; all-tile interiors are the most premium. The finish is applied as the final step of construction and the central step of resurfacing. **Key Characteristics:** - The water-contact surface layer over the shell - Determines the pool's color and texture - Wears out before the shell and is renewed by resurfacing **Practical Application:** When a pool surface becomes rough, stained, or cracked, the interior finish, not the shell, is what is being renewed during a resurfacing project. **Adams Pool Solutions Perspective:** We install plaster, pebble, glass-bead aggregate, fiberglass, Eco-Finish, and all-tile finishes, with crews specializing in each. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Plaster, Pebble Finish, Pool Resurfacing **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Waterline **Definition:** The waterline is the level at which a pool's water surface meets the interior wall. It is the band where waterline tile is installed and where surface debris, oils, and mineral scale tend to accumulate. **Extended Explanation:** The waterline is a focal point of a pool both visually and functionally. Visually, it is the most-seen band of the pool and is finished with decorative waterline tile. Functionally, it is where the water surface deposits oils, scale, and grime, so it needs durable, easy-to-clean material. Because the waterline experiences constant wetting and drying and chemical exposure, tile is the standard material there rather than plaster, which would erode and stain quickly at that band. **Key Characteristics:** - The band where water surface meets the pool wall - Finished with decorative, durable waterline tile - Prone to oil, scale, and debris accumulation **Practical Application:** When waterline tile loosens or falls off, it is replaced as part of a resurfacing or remodel, since the band is exposed when the pool is drained. **Adams Pool Solutions Perspective:** We replace waterline tile with ceramic and glass options as part of resurfacing and remodel projects, work performed by our in-house masonry crews. See our [tile and coping page](/products/tile-and-coping/). **Related Terms:** Waterline Tile, Coping, Interior Finish **Learn More:** - [Tile and Coping](/products/tile-and-coping/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Residential Pool **Definition:** A residential pool is a swimming pool built for a private home and household use. Residential pools are smaller than commercial pools and are designed around a homeowner's space, budget, and aesthetic goals. **Extended Explanation:** Residential pools cover a wide range, from compact backyard pools to large custom designs with spas, sun shelves, and water features. They are designed to integrate with a property's landscape and hardscape. Residential pool work splits into two streams: new construction, where a pool is designed and built from scratch, and renovation, where an existing pool is resurfaced or remodeled. Aging residential pools, often 20 to 50 years old, make up a large share of pool industry work. **Key Characteristics:** - Built for a single private household - Designed around the homeowner's property and budget - Served by both new construction and renovation work **Practical Application:** A homeowner with a 30-year-old pool showing rough plaster and falling tile is a typical residential renovation customer; a homeowner adding a pool to a new backyard is a residential construction customer. **Adams Pool Solutions Perspective:** We build custom residential pools and remodel existing ones, with hands-on supervision from design through first fill. See our [residential pool construction service](/services/residential-pool-construction/). **Related Terms:** Commercial Pool, Pool Remodel, Custom Pool **Learn More:** - [Residential Pool Construction](/services/residential-pool-construction/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Commercial Pool **Definition:** A commercial pool is a swimming pool built for public, institutional, or shared use, such as a hotel, resort, school, municipal aquatic center, therapy facility, or HOA community. Commercial pools are larger and built to stricter performance standards than residential pools. **Extended Explanation:** Commercial pools serve many users, which raises the requirements for durability, filtration capacity, code compliance, and accessibility. They include competition pools sized to 25-yard or 50-meter standards, dive pools, recreational pools, therapy pools, and HOA community pools. Commercial projects often run on tight, deadline-driven schedules and require a contractor with the manpower and superintendents to staff large-scale work. Performance standards, such as competition-ready surfaces, are higher than for typical backyard pools. **Key Characteristics:** - Built for public, institutional, or shared use - Larger and held to stricter performance standards - Often deadline driven, requiring substantial crew capacity **Practical Application:** A school replacing a competition pool's plaster, or an HOA renovating its community pool, is undertaking a commercial pool project rather than a residential one. **Adams Pool Solutions Perspective:** We build and renovate commercial pools for hotels, schools, colleges, municipalities, therapy centers, and HOA communities, and can scale crews to meet narrow completion windows. See our [commercial pool construction service](/services/commercial-pool-construction/). **Related Terms:** Residential Pool, Competition Pool, HOA Pool **Learn More:** - [Commercial Pool Construction](/services/commercial-pool-construction/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ## Surface Preparation and Construction Terms describing how a pool shell is built and prepared. ### Gunite **Definition:** Gunite is a dry-mix method of pneumatically applying concrete to form a pool shell. Dry cement and sand travel through a hose and water is added at the spray nozzle, producing a strong, monolithic concrete structure over steel reinforcement. **Extended Explanation:** Gunite is one of the two common ways to build a concrete pool shell. Because the concrete is sprayed rather than poured into forms, it can follow any pool shape, including curves, steps, and benches. The dry-mix characteristic means the nozzle operator controls the water added at the point of application. A skilled crew produces a dense, structurally sound shell. After application, the gunite must cure before construction continues. Gunite shells are durable and form the long-lasting structural core of most modern in-ground pools. **Key Characteristics:** - Dry cement and sand mixed with water at the nozzle - Sprayed over steel reinforcement to form the shell - Cures into a strong, monolithic, shapeable structure **Practical Application:** A custom pool with curved walls and integrated steps is built with a gunite or shotcrete shell because sprayed concrete can follow shapes that poured forms cannot. **Adams Pool Solutions Perspective:** We build gunite pool shells, and our warranty terms reflect the distinction between gunite new construction and gunite remodel work. **Related Terms:** Shotcrete, Pool Shell, Steel Reinforcement **Learn More:** - [Residential Pool Construction](/services/residential-pool-construction/) - [Pool Warranty Information](/warranty/) --- ### Shotcrete **Definition:** Shotcrete is a wet-mix method of pneumatically applying concrete to form a pool shell. The concrete is fully mixed with water before being pumped and sprayed over steel reinforcement. **Extended Explanation:** Shotcrete is the wet-mix counterpart to gunite. Because the concrete is pre-mixed to a consistent ratio before spraying, the water content is controlled at the mixer rather than at the nozzle. Like gunite, shotcrete is sprayed, so it can form complex pool shapes, and it produces a strong monolithic shell. On large or complex projects, shotcrete may be applied in controlled stages to manage curing and prevent stress fractures. In everyday industry conversation, the terms gunite and shotcrete are often used loosely and interchangeably; both deliver a durable concrete shell. **Key Characteristics:** - Concrete pre-mixed with water before spraying - Sprayed over steel reinforcement to form the shell - May be applied in stages on complex projects **Practical Application:** On a structurally complex commercial pool, shotcrete applied in stages helps prevent stress fractures during curing. **Adams Pool Solutions Perspective:** We apply shotcrete in controlled stages on complex projects to prevent stress fractures during curing, as we did rebuilding an active therapy pool wall. **Related Terms:** Gunite, Pool Shell, Curing **Learn More:** - [Commercial Pool Construction](/services/commercial-pool-construction/) - [Residential Pool Construction](/services/residential-pool-construction/) --- ### HydroBlasting **Definition:** HydroBlasting, also called water-jetting, is a pool surface-preparation method that uses a high-pressure water stream, around 40,000 PSI, to strip a pool's old interior surface without damaging the underlying concrete shell. **Extended Explanation:** Before a new finish can be applied, the old surface must be removed. HydroBlasting accomplishes this with water rather than impact. A diesel-driven compressor generates a 40,000 PSI stream that pulverizes the existing plaster surface. The key advantage is preservation of the substrate. Independent engineering studies have concluded that water-jetting removes surface material while keeping the shell intact. By contrast, jackhammer removal sends shock waves into the concrete that can create micro-fractures. Because the bond of a new finish depends on a sound, properly profiled shell, HydroBlasting directly affects how long a resurfacing job lasts. **Key Characteristics:** - Uses an approximately 40,000 PSI water stream - Removes the old surface without micro-fracturing the shell - Faster and cleaner than mechanical removal **Practical Application:** When an old pool surface must be removed before resurfacing, HydroBlasting strips it in roughly a day while preserving the shell, setting up a strong bond for the new finish. **Adams Pool Solutions Perspective:** HydroBlast water-jetting is a core part of how we work, and we back hydroblasted resurfacing with a 10-year warranty on the new surface bond. See our [surface preparation service](/services/surface-prep/). **Related Terms:** Mechanical Removal, Surface Preparation, Surface Bond **Learn More:** - [Surface Preparation](/services/surface-prep/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Mechanical Removal **Definition:** Mechanical removal is the surface-preparation method of stripping a pool's old interior surface with air-driven jackhammers and hand tools. It is the traditional alternative to HydroBlasting. **Extended Explanation:** Mechanical removal, sometimes called stripping or chip-out, uses impact tools to break the old plaster or finish off the shell. It is a proven, long-used method and is still effective for many projects. The trade-off is that impact tools transmit shock into the concrete shell, which can create micro-fractures. A new finish applied over a micro-fractured shell may suffer bond failure within a few years. For this reason, water-jetting is often preferred when shell preservation is a priority, though mechanical removal remains a valid option depending on the pool. **Key Characteristics:** - Uses air-driven jackhammers and hand tools - A proven, traditional preparation method - Impact can transmit shock into the shell **Practical Application:** On some projects, crews use mechanical removal where it is the practical choice; on others, water-jetting is selected specifically to protect the shell. **Adams Pool Solutions Perspective:** We use both HydroBlasting and mechanical removal, treating proper preparation, by either method, as the difference between a permanently bonded surface and an early failure. See our [surface preparation service](/services/surface-prep/). **Related Terms:** HydroBlasting, Surface Preparation, Structural Crack **Learn More:** - [Surface Preparation](/services/surface-prep/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Surface Bond **Definition:** Surface bond is the adhesion between a pool's interior finish and the concrete shell beneath it. A strong surface bond keeps the finish permanently attached; a weak bond leads to delamination and early surface failure. **Extended Explanation:** The bond is the unseen factor that determines whether a resurfacing job lasts. Even a high-quality finish material will fail prematurely if it does not bond firmly to the shell. Bond strength depends on surface preparation. The shell must be cleaned, properly profiled, and free of the micro-fractures that impact removal can cause. When preparation is done well, the new finish grips the shell mechanically and stays in place for the material's full lifespan. A contractor's confidence in its surface bond is often reflected in the length of the bond warranty offered. **Key Characteristics:** - The adhesion between interior finish and shell - Determined largely by surface preparation quality - A weak bond causes delamination and early failure **Practical Application:** A resurfacing finish that delaminates within five to seven years usually indicates a surface-bond failure traced back to poor preparation. **Adams Pool Solutions Perspective:** We back hydroblasted resurfacing with a 10-year bond warranty, which reflects our confidence in the preparation step. See our [warranty page](/warranty/). **Related Terms:** HydroBlasting, Surface Preparation, Delamination **Learn More:** - [Surface Preparation](/services/surface-prep/) - [Pool Warranty Information](/warranty/) --- ### Steel Reinforcement **Definition:** Steel reinforcement is the grid of steel rebar tied inside a pool's form before concrete is applied. It gives the gunite or shotcrete shell its tensile strength and resistance to cracking. **Extended Explanation:** Concrete is strong in compression but weak in tension. Steel reinforcement compensates by carrying tensile loads, so the shell can resist soil movement, water pressure, and other forces that would otherwise crack plain concrete. The rebar is tied into a grid that follows the pool's shape, including walls, floor, steps, and benches. Reinforcement is calculated for the loads a particular pool will experience, and specialized structures like dive pools or therapy pools with heavy equipment require engineered reinforcement. **Key Characteristics:** - A grid of steel rebar inside the pool form - Provides tensile strength to the concrete shell - Engineered for the loads a specific pool will carry **Practical Application:** A dive tower pool or a therapy pool with mounted equipment requires steel reinforcement calculated for asymmetric or concentrated loads beyond a standard residential pool. **Adams Pool Solutions Perspective:** On commercial projects we install steel reinforcement calculated for the specific loads of the facility, including the asymmetric loads of therapy equipment. **Related Terms:** Gunite, Shotcrete, Pool Shell **Learn More:** - [Commercial Pool Construction](/services/commercial-pool-construction/) - [Residential Pool Construction](/services/residential-pool-construction/) --- ## Surface Materials and Finishes The interior finish options available for a pool. ### Plaster **Definition:** Plaster is the traditional cement-based interior pool finish. It is a smooth mixture troweled onto the shell that gives a pool its classic light-blue appearance. It is the most economical finish and typically lasts 7 to 10 years. **Extended Explanation:** Plaster has been the industry-standard pool finish since swimming pools first came into use. It is smooth to the touch, gives the familiar clean light-blue color, and has a long, proven track record. Its main limitation is durability. Plaster contains crushed sand and is the interior material most susceptible to the natural erosive action of water. Over 7 to 10 years it roughens, stains, and may crack, after which it needs replacement. White plaster is the economical baseline finish, which keeps it a common choice despite its shorter lifespan. **Key Characteristics:** - Cement-based finish troweled onto the shell - Smooth surface with a light-blue appearance - Most economical finish, lasts roughly 7 to 10 years **Practical Application:** A budget-focused owner who plans to keep a pool only a few more years may choose white plaster; an owner planning long-term ownership often upgrades to pebble. **Adams Pool Solutions Perspective:** We install white plaster and explain its trade-offs against longer-lasting finishes during the estimate. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Colored Plaster, Pebble Finish, Interior Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Colored Plaster **Definition:** Colored plaster is white plaster with added pigment, used to give a pool a color other than the standard light blue. It has a lifespan similar to white plaster but tends to fade and show surface unevenness over time. **Extended Explanation:** Adding pigment to plaster expands the color palette and lets a pool match a backyard design. However, colored plaster has notable drawbacks. The pigment accentuates the natural unevenness of the troweled surface, and the effect can be dramatic from the start. The color rarely matches the anticipated shade exactly, and it fades over the life of the finish. Because of these issues, the industry has largely moved away from colored plaster in favor of pebble and aggregate finishes that hold their color. **Key Characteristics:** - White plaster with added pigment - Tends to show surface unevenness and fade - Largely superseded by pebble and aggregate finishes **Practical Application:** An owner wanting a darker or non-standard water color is generally steered toward a pebble or aggregate finish rather than colored plaster, because those hold color far better. **Adams Pool Solutions Perspective:** We are candid that the industry has moved away from colored plaster, and we help owners choose color-stable pebble or aggregate finishes instead. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Plaster, Pebble Finish, Aggregate Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Pebble Finish **Definition:** A pebble finish is an exposed-aggregate pool interior made of small water-washed pebbles mixed with colored cement. It is durable, holds its color throughout the pool's life, and typically lasts 15 to 25 years, far longer than plaster. **Extended Explanation:** Pebble finishes have evolved over the past several decades and now dominate the pool finish market. Small pebbles in multiple colors are mixed with colored cement, applied, and then exposed with water to reveal a natural-looking surface resembling a mosaic or granite. The advantages over plaster are substantial. Pebble is highly resistant to the erosive action of water and practically impervious to normal water-chemistry fluctuations. Because the color comes from the stone itself, it stays consistent rather than fading like pigment. The surface has a textured feel but is not rough, as the pebbles are rounded by water. Pebble finishes cost more upfront, but the much longer lifespan offsets the higher initial price on a cost-per-year basis. **Key Characteristics:** - Water-washed pebbles in colored cement, water-exposed - Highly durable and resistant to water-chemistry swings - Holds color and typically lasts 15 to 25 years **Practical Application:** An owner replacing a worn 50-year-old plaster surface and planning long-term ownership commonly chooses a pebble finish for its longevity and color stability. **Adams Pool Solutions Perspective:** We manufacture our own Pebble Plus pebble surface line and carry a 10-year product warranty on it. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Aggregate Finish, Plaster, Interior Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Aggregate Finish **Definition:** An aggregate finish is a pool interior that combines cement with exposed mineral material such as pebbles, quartz, ceramic sand, or glass beads. Aggregate finishes are harder, more durable, and offer a wider color range than plain plaster. **Extended Explanation:** Aggregate is the broad category that includes pebble finishes and aggregate-effect finishes. Exposed aggregate uses pebbles; aggregate-effect finishes add colored ceramic sand or small glass beads to quartz-based plaster, which expands the color palette while increasing hardness and durability. A further variation, exposed aggregate with glass, adds multi-colored glass beads to a pebble surface for a reflective sparkle. Each step up in the aggregate range generally adds cost. Some aggregate-effect products can be sensitive to extreme water-chemistry conditions. **Key Characteristics:** - Cement combined with exposed mineral aggregate - Harder and more durable than plain plaster - Includes pebble, quartz, ceramic, and glass-bead variations **Practical Application:** An owner wanting a specific decorative color with sparkle, plus durability, is a candidate for a glass-bead aggregate finish rather than plaster or a plain pebble surface. **Adams Pool Solutions Perspective:** We install the full aggregate range, including pebble and glass-bead products, and match the finish to the pool's use and the owner's color goals. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Pebble Finish, Quartz Finish, Glass Bead Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Glass Bead Finish **Definition:** A glass bead finish is a pool interior that incorporates small multi-colored glass beads, either blended into a pebble surface or into quartz-based plaster, to add a reflective, sparkling quality to the water. **Extended Explanation:** Glass beads are a relatively recent innovation in pool finishes. Added to a pebble surface, they bring all the durability benefits of traditional pebble plus a reflective pop of color. Added to quartz-based plaster as an aggregate effect, they increase hardness and expand the color palette. The reflective quality changes how the water reads, adding depth and shimmer. Glass-bead products carry a modest cost increase over standard pebble, and as with other aggregate-effect finishes, extreme water chemistry can be hard on some variations. **Key Characteristics:** - Incorporates small multi-colored glass beads - Adds reflective sparkle to the water surface - A modest cost step above standard pebble **Practical Application:** An owner who wants a high-end shimmering water appearance, and durability close to pebble, chooses a glass-bead finish. **Adams Pool Solutions Perspective:** We offer glass-bead pebble products, including reflective Pebble Plus options, and show samples so owners can see the effect before deciding. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Aggregate Finish, Pebble Finish, Quartz Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Fiberglass Finish **Definition:** A fiberglass finish is a non-cement pool interior applied over a smooth troweled surface. Its main advantage is tensile strength, which makes it valuable as part of a repair system for badly cracked pool shells. **Extended Explanation:** A fiberglass interior is distinct from a fiberglass pool. As an interior finish, fiberglass is applied over a smooth substrate and forms an impermeable barrier that resists extreme water-chemistry conditions. Its standout property is tensile and flexural strength. When combined with structural treatment of cracks in the shell, a fiberglass layer helps hold a cracked pool shell together and resist further movement. This makes it a preferred solution for pools with significant shell cracking. The trade-offs are a higher price and an appearance some owners describe as plastic-looking. For the right pool, especially a badly cracked one, it is the best solution. **Key Characteristics:** - Non-cement finish applied over a smooth substrate - Provides tensile and flexural strength - Used as part of a repair system for cracked shells **Practical Application:** A pool with extensive structural cracking can be stabilized with a fiberglass repair system that treats the cracks and adds a strength-bearing fiberglass layer. **Adams Pool Solutions Perspective:** We use fiberglass as part of crack repair systems and as an interior finish where extreme water chemistry or shell cracking calls for it. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Eco-Finish, Structural Crack, Interior Finish **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Surface Preparation](/services/surface-prep/) --- ### Eco-Finish **Definition:** Eco-Finish is a polymer-based pool interior finish that is rolled onto the shell and cured with a torch. It forms an extremely smooth, completely impermeable surface that resists water-chemistry fluctuations. **Extended Explanation:** Eco-Finish is a non-cement, polymer surface. It is applied like a coat of paint, rolled on and then instantly set by torch curing. The result is a very smooth, moisture-impermeable layer that is highly durable and resistant to water-chemistry swings. Because it is rolled on, Eco-Finish must be applied over a completely smooth troweled substrate, which limits where it can be used. It also sits near the top of the interior-finish price range. For owners who value its smoothness and impermeability, it is a strong choice within those constraints. **Key Characteristics:** - Polymer finish rolled on and torch-cured - Extremely smooth and completely impermeable - Requires a smooth troweled substrate **Practical Application:** An owner dealing with difficult water chemistry, who has a pool that can take a smooth troweled base, may choose Eco-Finish for its impermeability. **Adams Pool Solutions Perspective:** We install Eco-Finish where its impermeability and smoothness suit the pool, and we are clear about the smooth-substrate requirement. See our [pool surface options](/products/pool-surface-options/). **Related Terms:** Fiberglass Finish, Interior Finish, Plaster **Learn More:** - [Pool Surface Options](/products/pool-surface-options/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### All-Tile Interior **Definition:** An all-tile interior is a pool finish in which the entire interior surface is covered in tile rather than plaster or aggregate. It is the most premium and longest-lasting interior option, offering the widest range of colors and patterns. **Extended Explanation:** An all-tile interior takes the durability and richness of waterline tile and extends it across the whole pool. It delivers a level of beauty, color depth, and pattern flexibility that cement-based surfaces cannot match. All-tile interiors are also the most durable surface option, retaining their appearance well beyond the lifespan of other finishes. The trade-off is cost: an all-tile interior is the most expensive interior choice and is typically selected by owners seeking the highest level of finish. **Key Characteristics:** - The entire interior surface covered in tile - The most durable and premium interior option - The widest color and pattern range, at the highest cost **Practical Application:** A discerning owner who wants the most luxurious, longest-lasting pool interior and a flawless appearance chooses an all-tile interior. **Adams Pool Solutions Perspective:** We install all-tile pool interiors for owners who want the premium end of the market, drawing on the masonry craftsmanship the company was founded on. See our [tile and coping page](/products/tile-and-coping/). **Related Terms:** Waterline Tile, Interior Finish, Pebble Finish **Learn More:** - [Tile and Coping](/products/tile-and-coping/) - [Pool Surface Options](/products/pool-surface-options/) --- ## Pool Components and Features The physical parts and features of a swimming pool. ### Coping **Definition:** Coping is the capping material installed around the top edge of a pool, where the pool wall meets the surrounding deck. It finishes the pool's edge and is commonly made of cast stone, travertine, flagstone, or precast concrete. **Extended Explanation:** Coping serves both function and appearance. Functionally, it caps the shell's edge, provides a finished transition to the deck, and gives swimmers a defined edge to grip. Visually, it frames the pool and sets much of its style. Materials range widely. Natural stone such as travertine and flagstone offers organic texture and color. Manufactured cast stone provides consistency and a range of profiles. Coping ages and can crack or stain, so it is often replaced during a remodel along with waterline tile. **Key Characteristics:** - Caps the top edge where the pool wall meets the deck - Made of cast stone, travertine, flagstone, or precast concrete - Frames the pool and is often replaced during remodels **Practical Application:** During a pool remodel, cracked or dated coping is replaced along with waterline tile to refresh the pool's entire edge. **Adams Pool Solutions Perspective:** We install coping in travertine, flagstone, and our own Golden State Cast Stone, with all masonry performed by in-house crews. See our [tile and coping page](/products/tile-and-coping/). **Related Terms:** Waterline Tile, Cast Stone, Pool Deck **Learn More:** - [Tile and Coping](/products/tile-and-coping/) - [Pool Remodeling](/services/pool-resurfacing/) --- ### Waterline Tile **Definition:** Waterline tile is the band of decorative tile installed along a pool's interior at the waterline. It provides a durable, easy-to-clean surface where the water meets the wall and is a key visual element of the pool. **Extended Explanation:** Waterline tile sits exactly where the water surface contacts the pool wall, a band that experiences constant wetting, drying, and chemical exposure. Tile is used there because it resists the staining and erosion that would quickly affect plaster at the waterline. It is also decorative. Ceramic and glass tile come in a wide range of colors and patterns, and the waterline band is one of the most visible parts of a pool. Over time, the tile bond and grout age, and tiles can loosen or fall, signaling that replacement is due. **Key Characteristics:** - Decorative tile band at the pool's waterline - Durable and easy to clean at a high-exposure band - Available in a wide range of ceramic and glass options **Practical Application:** When waterline tiles begin falling off an aging pool, they are replaced during resurfacing or a remodel, when the band is exposed and masonry crews are on site. **Adams Pool Solutions Perspective:** We replace waterline tile with ceramic and glass options as part of resurfacing and remodel projects. See our [tile and coping page](/products/tile-and-coping/). **Related Terms:** Coping, Waterline, All-Tile Interior **Learn More:** - [Tile and Coping](/products/tile-and-coping/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Cast Stone **Definition:** Cast stone is a manufactured masonry product made to resemble natural stone, used in pools primarily as coping. It offers consistent dimensions, a range of profiles and colors, and durability suited to the pool environment. **Extended Explanation:** Cast stone is produced by casting a concrete-based mixture in molds, which gives it the look of natural stone with greater consistency than quarried material. For pool coping, that consistency makes installation predictable and the finished edge uniform. Cast stone comes in many profiles and colors, so it can match a wide range of pool and deck styles. It is durable in the wet, chemically exposed pool environment, which is why it is a common coping choice. **Key Characteristics:** - Manufactured masonry product resembling natural stone - Consistent dimensions and a range of profiles and colors - Durable in the pool environment, commonly used for coping **Practical Application:** An owner who wants a uniform, predictable coping edge in a specific color often chooses cast stone over variable natural stone. **Adams Pool Solutions Perspective:** We manufacture our own Golden State Cast Stone coping, giving owners a consistent, durable edge material backed by the company's masonry roots. **Related Terms:** Coping, Waterline Tile, Pool Deck **Learn More:** - [Tile and Coping](/products/tile-and-coping/) - [Pool Remodeling](/services/pool-resurfacing/) --- ### Pool Equipment **Definition:** Pool equipment is the mechanical system that circulates, filters, heats, and sanitizes a pool's water. It includes the pump, filter, heater, and sanitation system, and may be tied into an automation controller. **Extended Explanation:** Pool equipment keeps water clean, clear, and at a comfortable temperature. The pump circulates water, the filter removes debris, the heater controls temperature, and sanitation maintains water quality. These components have finite service lives and eventually need replacement. Modern equipment is more energy efficient than older models, and energy codes have tightened over time, so equipment upgrades during a remodel can both cut operating costs and bring a pool into current compliance. Equipment can also be linked to automation for remote control. **Key Characteristics:** - Pump, filter, heater, and sanitation system - Circulates, filters, heats, and sanitizes the water - Has a finite service life and is upgraded for efficiency **Practical Application:** During a remodel of an aging pool, owners commonly replace old pumps and heaters with energy-efficient models to lower operating costs and meet current codes. **Adams Pool Solutions Perspective:** We upgrade filtration, heating, and equipment systems as part of remodels, sizing new systems to the pool's needs. See our [pool equipment page](/products/pool-equipment/). **Related Terms:** Pool Automation, Pool Remodel, Energy Code **Learn More:** - [Pool Equipment](/products/pool-equipment/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Pool Automation **Definition:** Pool automation is a control system that lets a pool owner manage equipment, such as the pump, heater, lighting, and water features, from a single panel or a mobile device. It improves convenience and energy management. **Extended Explanation:** Automation links a pool's equipment to a central controller. Instead of operating each component manually, the owner schedules and adjusts the pump, heater, LED lighting, water features, and sometimes the spa from one interface, often a phone app. Beyond convenience, automation supports energy efficiency by running equipment on optimized schedules. It is a common addition during a remodel, when the equipment pad is already being updated. **Key Characteristics:** - Centralized control of pumps, heaters, lighting, and features - Operated from a panel or a mobile device - Supports convenience and energy-efficient scheduling **Practical Application:** An owner remodeling a pool and updating the equipment pad often adds automation so the whole system can be scheduled and controlled from a phone. **Adams Pool Solutions Perspective:** We integrate energy-saving automation into remodels alongside equipment upgrades. See our [pool equipment page](/products/pool-equipment/). **Related Terms:** Pool Equipment, Pool Remodel, LED Pool Lighting **Learn More:** - [Pool Equipment](/products/pool-equipment/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Automatic Pool Cover **Definition:** An automatic pool cover is a motorized cover that extends across and retracts from a pool's surface at the press of a button. It supports safety, heat retention, water conservation, and reduced debris. **Extended Explanation:** An automatic pool cover runs on tracks along the pool's edge and is driven by a motor, so it can be deployed quickly without manual handling. When closed, it provides a safety barrier over the water, retains heat, slows evaporation, and keeps out leaves and debris. Installing an automatic cover often involves structural considerations, such as the track placement and a vault to house the cover mechanism, which is why it is frequently added during new construction or a remodel rather than as a standalone retrofit. **Key Characteristics:** - Motorized cover that extends and retracts on tracks - Supports safety, heat retention, and water conservation - Often installed during construction or a remodel **Practical Application:** An owner wanting a safety barrier and lower heating and evaporation costs adds an automatic pool cover, typically planned into a remodel so the track and vault can be built in. **Adams Pool Solutions Perspective:** We install automatic pool covers, including the structural vault and track work, as part of new construction and remodels. **Related Terms:** Pool Equipment, Pool Remodel, Pool Deck **Learn More:** - [Pool Resurfacing](/services/pool-resurfacing/) - [Residential Pool Construction](/services/residential-pool-construction/) --- ## Renovation and Remodeling Terms describing the renewal of an existing pool. ### Pool Resurfacing **Definition:** Pool resurfacing is the process of removing a pool's worn interior finish and applying a new one. It restores a smooth, watertight, attractive surface and is the central job in renewing an aging pool. **Extended Explanation:** Resurfacing addresses the part of a pool that wears out first: the interior finish. The process strips the failing surface, prepares the shell, repairs cracks, and applies a new finish, which may match the old material or upgrade it. Resurfacing is needed when plaster becomes rough or stained, when cracks appear, or when an owner wants to change the surface material. It is distinct from a full remodel, though the two are often combined. A resurfacing-only project can be completed in roughly ten days. **Key Characteristics:** - Removes the worn interior finish and applies a new one - Includes shell preparation and crack repair - Often combined with tile, coping, or equipment work **Practical Application:** A pool with rough, stained 20-year-old plaster is resurfaced to restore a smooth surface, often with an upgrade to a longer-lasting pebble finish. **Adams Pool Solutions Perspective:** Pool resurfacing is a core service, performed by in-house crews with a dedicated onsite supervisor on every project. See our [pool resurfacing service](/services/pool-resurfacing/). **Related Terms:** Replastering, Pool Remodel, Interior Finish **Learn More:** - [Pool Resurfacing](/services/pool-resurfacing/) - [Surface Preparation](/services/surface-prep/) --- ### Replastering **Definition:** Replastering is the specific process of removing a pool's old plaster and applying a fresh plaster finish. It is one type of resurfacing, focused on renewing a plaster surface in particular. **Extended Explanation:** Replastering is the traditional pool-renewal job: strip the old plaster, prepare the shell, and trowel on a new plaster coat. It restores the smooth, light-blue surface a plaster pool started with. The term is narrower than resurfacing. Resurfacing covers renewal with any interior material, while replastering specifically means a like-for-like plaster renewal. When owners want to upgrade from plaster to a pebble or aggregate finish, the job is still resurfacing but is no longer described as replastering. **Key Characteristics:** - Removes old plaster and applies a fresh plaster coat - A specific type of resurfacing - Keeps a plaster finish rather than upgrading the material **Practical Application:** An owner who is satisfied with plaster and simply wants the surface renewed chooses replastering; an owner who wants a more durable finish resurfaces with pebble instead. **Adams Pool Solutions Perspective:** We perform replastering and explain to owners when staying with plaster makes sense versus upgrading to a longer-lasting finish.

It is broader in scope than resurfacing alone. **Extended Explanation:** Where resurfacing renews the interior surface, a remodel can touch every part of the pool. Typical remodel elements are new waterline tile and coping, modern energy-efficient equipment, LED lighting, water features, a spa, an automatic cover, and sometimes structural changes to the pool's shape or depth. A remodel is the efficient time to combine several improvements, because the pool is already drained and crews are mobilized. It is also the moment to address efficiency-code compliance and resolve long-standing problems in one coordinated project. **Key Characteristics:** - Updates multiple pool elements in one project - Can include surface, tile, coping, equipment, and features - Broader in scope than resurfacing alone **Practical Application:** An owner whose aging pool has a worn surface, failing tile, dated equipment, and no spa undertakes a full remodel to address all of it at once. **Adams Pool Solutions Perspective:** We manage full remodels with in-house design, masonry, plumbing, and electrical crews, so an entire project runs under one roof. See our [pool resurfacing service](/services/pool-resurfacing/). **Related Terms:** Pool Resurfacing, Pool Equipment, Coping **Learn More:** - [Pool Resurfacing](/services/pool-resurfacing/) - [Tile and Coping](/products/tile-and-coping/) --- ### Structural Crack **Definition:** A structural crack is a crack that extends into a pool's concrete shell, as opposed to a cosmetic crack confined to the surface finish. Structural cracks must be repaired before a new interior finish is applied. **Extended Explanation:** Cracks fall into two categories. Cosmetic cracks affect only the interior finish and are removed automatically when the surface is stripped during resurfacing. Structural cracks penetrate the shell itself and require active repair. Covering a structural crack without treating it lets the crack telegraph back through the new finish and can lead to leaks. Repair methods range from staples and hand-packed high-strength concrete for minor cracks to a fiberglass repair system for a badly cracked shell, which combines structural crack treatment with a strength-bearing fiberglass layer. **Key Characteristics:** - A crack extending into the concrete shell - Distinct from a cosmetic surface-finish crack - Must be repaired before a new finish is applied **Practical Application:** A pool with cracks running through 166 feet of shell, for example, requires structural crack repair, potentially with a fiberglass repair system, before resurfacing can proceed. **Adams Pool Solutions Perspective:** We repair structural cracks as part of the resurfacing scope, using staples, hand-packed high-strength concrete, and fiberglass repair systems as the severity requires.

In Bay Area counties, a permit is required for any pool work, including a simple replaster, new construction, and remodels. **Extended Explanation:** A building permit ensures that pool work meets local code and is inspected at appropriate stages. Every Bay Area county requires a permit for any pool project, no matter how minor. Requirements in other markets, such as Clark County in the Las Vegas area, are set locally and can evolve. The contractor typically prepares and submits the permit application and coordinates inspections, while the property owner pays the permit fees. Permit processing currently runs long in many jurisdictions, so the lead time must be built into the project schedule. Permitted, inspected work also avoids problems at resale. **Key Characteristics:** - Government authorization required for pool work - Required in Bay Area counties even for a simple replaster - Contractor applies; owner pays the permit fees **Practical Application:** Before resurfacing or building a pool in the Bay Area, a permit must be obtained, with processing time factored into the start date. **Adams Pool Solutions Perspective:** We handle the permit application and procurement and coordinate inspections; the client is responsible for the cost of the permit itself. See our [FAQ page](/faqs/). **Related Terms:** Inspection, Energy Code, Pool Resurfacing **Learn More:** - [Frequently Asked Questions](/faqs/) - [Pool Resurfacing](/services/pool-resurfacing/) --- ### Energy Code **Definition:** An energy code is a set of regulations governing the energy efficiency of building systems, including pool equipment. In California, Title 24 sets energy-efficiency standards that affect pool pumps, heaters, and related equipment. **Extended Explanation:** Energy codes have tightened over time, raising the efficiency requirements for new and replacement pool equipment. California's Title 24 standards apply to pool construction and equipment, and updates to those standards influence which pumps, heaters, and systems may be installed. For pool owners, an energy code matters most during new construction and equipment upgrades. Replacing old equipment during a remodel both lowers operating costs and brings the pool into current code compliance. **Key Characteristics:** - Regulations governing the energy efficiency of pool equipment - In California, governed by Title 24 standards - Most relevant during construction and equipment upgrades **Practical Application:** A homeowner replacing an old pool heater during a remodel must select a model that meets current energy-code requirements. **Adams Pool Solutions Perspective:** We work within California Title 24 requirements on construction and equipment upgrades, and our expertise blog covers Title 24 and pool construction in detail. See our [expertise blog](/expertise/). **Related Terms:** Pool Equipment, Building Permit, Pool Automation **Learn More:** - [Pool Equipment](/products/pool-equipment/) - [Expertise Blog](/expertise/) --- ### Water Chemistry **Definition:** Water chemistry is the balance of pH, sanitizer, alkalinity, calcium hardness, and related factors in a pool's water. Balanced water chemistry is essential to swimmer safety and to the appearance and longevity of the interior finish. **Extended Explanation:** Pool water is a chemical system that must be kept in balance. Proper sanitizer levels keep the water safe; balanced pH, alkalinity, and calcium hardness keep the water comfortable and protect the pool's surfaces. Water chemistry has a direct effect on how long an interior finish lasts. Unbalanced or aggressive water accelerates erosion of plaster and can be hard on some aggregate-effect finishes. This is why a contractor will emphasize maintaining balanced water chemistry regardless of which surface material an owner chooses. **Key Characteristics:** - The balance of pH, sanitizer, alkalinity, and hardness - Essential to swimmer safety - A primary factor in interior-finish longevity **Practical Application:** A pool owner who wants a new pebble finish to reach its full 15-to-25-year lifespan must maintain balanced water chemistry throughout that time. **Adams Pool Solutions Perspective:** We advise owners that balanced water chemistry is critical to protecting the appearance and longevity of any interior finish we install.
