Why Choose Composite Decking Around Inground Pool Areas?
Many homeowners opt for composite decking around inground pool spaces due to its numerous advantages over traditional materials such as wood or concrete. Here’s why:
1. Water and Moisture Resistance
Unlike natural wood, composite decking is highly resistant to water and moisture. Given that inground pools create a constantly wet environment, traditional wood decks can absorb water, leading to swelling, warping, or rotting over time. Composite decking, made from a mix of recycled wood fibers and plastic, does not absorb water, making it an ideal material for pool surroundings.
2. Slip-Resistant Surface
Safety is a primary concern around pools, as wet surfaces can become slippery. High-quality composite decking around inground pool areas often features slip-resistant textures that provide better grip, reducing the risk of slips and falls. Many composite decking brands offer boards with embossed patterns or brushed finishes that enhance traction, ensuring a safer poolside experience.
3. Low Maintenance
Traditional wood decking requires regular staining, sealing, and refinishing to prevent water damage and UV fading. In contrast, composite decking requires minimal upkeep. Simply washing it with soap and water or a mild cleaner keeps it looking new, making it a hassle-free choice for busy homeowners who want a low-maintenance poolside.
4. Long-Lasting Durability
Composite decking is designed to withstand harsh outdoor conditions, including intense sunlight, heavy rains, and chlorine or saltwater exposure. High-end composite decking materials come with warranties of 25 years or more, ensuring that your poolside remains in top condition for decades without needing frequent repairs or replacements.
5. Aesthetic Appeal and Variety
Available in a wide range of colors, patterns, and finishes, composite decking allows homeowners to create a customized and visually appealing pool area. Whether you prefer a natural wood-like appearance or a modern, sleek design, there are plenty of options to match your outdoor décor.

Best Composite Decking Options for Underground Pools
When installing composite decking around an inground pool, selecting the right type is crucial for both aesthetics and functionality. Not all composite decking materials are created equal, and some are better suited for underground pool areas than others. Here are some of the best options:
1. Capped Composite Decking
Capped composite decking features a protective outer shell that enhances its resistance to moisture, stains, and UV damage. This type of decking is ideal for pool surroundings as it offers superior durability against water exposure and requires minimal upkeep. The cap layer prevents fading, which is essential in sunny pool areas.
2. Hollow Core Composite Decking
Hollow core composite decking is a lightweight option that provides excellent drainage, making it well-suited for underground pool areas where moisture accumulation is a concern. Unlike solid composite boards, hollow core boards have internal chambers that reduce weight while maintaining strength. They also help with air circulation, preventing trapped moisture and reducing the risk of mold growth in enclosed spaces. Additionally, hollow core decking is often more cost-effective than solid alternatives, making it a budget-friendly choice.
3. Textured or Embossed Surface Decking
For underground pool areas where safety is a priority, choosing composite decking with a textured or embossed surface can reduce slip hazards. Brands that offer anti-slip coatings or deeply grained finishes help provide better traction, ensuring a safer environment even when the surface is wet.
4. Light-Colored Composite Decking
Since underground pools often have enclosed or partially shaded surroundings, selecting lighter-colored composite decking can help brighten the space. Shades like light gray, beige, or soft oak reflect more light and prevent the area from feeling too dark or enclosed.
5. Weather-Resistant and Mold-Resistant Decking
Underground pool areas can retain more humidity than outdoor pools, increasing the risk of mold and mildew. Choosing a composite decking brand with built-in mold resistance will ensure long-lasting performance. Many high-end composites are designed with anti-microbial properties to prevent mold growth, even in damp environments.

Key Considerations for Installing Composite Decking Around Inground Pool
When planning to install composite decking around inground pool areas, it’s important to consider the following factors:
1. Heat Resistance
Dark-colored composite boards can absorb heat and become hot under direct sunlight. If your poolside gets a lot of sun, consider light-colored composite decking, which stays cooler to the touch. Some premium composite brands also incorporate heat-resistant technology to minimize heat absorption.
2. Pool Water Type: Chlorine vs. Saltwater
The type of pool water can impact the longevity of your deck. If you have a saltwater pool, ensure the composite decking you choose is resistant to salt corrosion. Most high-quality composite decking materials are designed to withstand both chlorine and saltwater exposure without deterioration.
3. Proper Drainage System
Water pooling on your deck can lead to mildew and algae buildup. Proper drainage is essential to prevent water from collecting under or on the deck surface. Ensure that your composite decking around inground pool areas has a slightly sloped design or an efficient drainage system to direct water away.
4. Installation Method
Most composite decking requires hidden fasteners or clips, which create a seamless, screw-free surface that enhances both aesthetics and safety. Ensure the deck is installed with expansion gaps to allow for natural expansion and contraction due to temperature changes.
5. Matching Poolside Features
To create a cohesive outdoor space, choose composite decking that complements other elements, such as pool coping, outdoor furniture, and landscaping. Many composite decking brands offer coordinating railing systems, skirting, and fascia boards to complete the look.

Installation Tips for Composite Decking Around Inground Pool
1. Prepare the Base
Ensure the ground or substructure is stable and properly leveled before installing the deck. If you’re building over a concrete pool surround, you may need a sleeper system (a framework of joists) to secure the decking.
2. Leave Expansion Gaps
Composite decking expands and contracts with temperature fluctuations. Leaving appropriate gaps (usually 1/8 to 1/4 inch) between boards allows for natural movement and prevents warping or buckling.
3. Use Stainless Steel Fasteners
To prevent rust and ensure long-term durability, always use stainless steel screws or hidden fastener systems designed for composite decking.
4. Consider a Picture Frame Border
Adding a picture frame border around the deck enhances aesthetics and provides a clean, finished look. This involves using contrasting or coordinating boards to create an outlined perimeter.
5. Ensure Proper Ventilation
Allow airflow beneath the decking to prevent moisture buildup, which could lead to mold or mildew growth. Adequate spacing between joists and ground clearance is necessary for good ventilation.

Maintenance Guide for Composite Decking Around Inground Pool
Although composite decking requires less maintenance than wood, regular care helps keep it in pristine condition:
1. Regular Cleaning
- Sweep debris and leaves frequently to prevent dirt buildup.
- Wash the deck every few months using a mild soap and water solution.
- Avoid harsh chemicals that can damage the protective coating.
2. Remove Stains Promptly
Sunscreen, pool chemicals, and spilled drinks can cause stains if left unattended. Clean up spills immediately with warm water and a gentle detergent.
3. Prevent Mold and Mildew
While composite decking is mold-resistant, damp environments can still encourage mildew growth. Use a mold remover or diluted vinegar solution to clean affected areas if necessary.
4. Protect Against Scratches
Although composite decking is highly durable, dragging heavy furniture or sharp objects can cause scratches. Use furniture pads and avoid placing metal objects directly on the deck.
5. Inspect for Damage
Periodically check for loose boards, fasteners, or structural issues. Address any minor problems promptly to prevent costly repairs in the future.
Enhancing the Poolside Experience with Composite Decking Features
Beyond selecting the right composite decking around an inground pool, integrating additional features can further improve the poolside experience. Whether it’s added functionality, increased comfort, or enhanced aesthetics, these elements can transform an ordinary pool deck into a luxurious retreat.
1. Built-In Seating and Lounging Areas
A well-designed poolside should include comfortable seating for relaxation. With composite decking, you can incorporate built-in benches or sun loungers that seamlessly blend into the deck’s design. Some homeowners even create multi-level decking structures that separate lounging areas from the main pool space, adding depth and style to the overall landscape.
2. Shade Structures and Pergolas
While composite decking is resistant to UV damage, creating shaded areas enhances comfort, especially in sunny regions. Pergolas, retractable awnings, or even large patio umbrellas can provide much-needed relief from the sun while maintaining the open-air feel of the pool area. A pergola with climbing plants or a stylish fabric canopy can also enhance the aesthetic appeal of your poolside.
3. Outdoor Showers and Rinse Stations
Installing an outdoor shower or a small rinse station near your inground pool deck helps keep dirt, sand, and chlorine residue from being tracked into your home. Composite decking is water-resistant, making it a practical base for such features. Pairing it with a matching privacy screen creates a stylish and functional addition.
4. Fire Pit or Outdoor Heating for Year-Round Use
For homeowners who want to enjoy their pool deck even in cooler months, adding a fire pit or outdoor heating system can extend usability beyond the summer season. Some composite decking materials are designed to withstand high temperatures, making them suitable for fire pits (always check manufacturer guidelines for safe placement).
5. Smart LED Lighting for Ambiance and Safety
Lighting plays a crucial role in both safety and ambiance when using your pool deck at night. Options such as:
- Recessed LED deck lights for subtle illumination
- Solar-powered lights for energy efficiency
- Color-changing LED strips for a modern, customizable vibe
