Why PVC Decking Excels in Poolside Environments
PVC (polyvinyl chloride) decking is a 100% synthetic material, meaning it contains no wood fibers. This composition is crucial for pool surrounds where boards are frequently exposed to water, chlorine, and direct sunlight. Unlike wood or even some composite materials, PVC boards are waterproof to the core, which helps prevent swelling, staining, or rot.
The inherent waterproof nature of PVC makes it a default choice for applications where boards are consistently wet, such as pool surrounds, docks, and even covered porches that experience weather from multiple sides. This material characteristic ensures long-term stability and appearance, even under continuous splash zone conditions.
Furthermore, PVC decking is known for its lighter weight compared to hardwood and many composite options. This can translate to easier handling during installation and potentially faster project completion, a benefit for any construction project.
Key Features of Azek and TimberTech Azek PVC Decking
Azek and TimberTech Azek PVC decking lines are designed with advanced capping technology. This outer layer provides enhanced resistance to staining from common poolside spills like grease or wine, making cleanup simpler with just soap and water. The capping also contributes to the material's fade resistance, helping to maintain its color and appearance over time.
These lines offer various collections, such as Vintage, Landmark, and Harvest, which are recognized for their deep wood-grain aesthetics, providing the look of natural wood without the associated maintenance. This allows homeowners to achieve a sophisticated outdoor design that complements their home and landscaping.
For areas like Montgomery, AL, where sun exposure can be intense, Azek and TimberTech Azek offer heat-mitigating color options. While no material remains completely cool in direct sunlight, these options are designed to absorb less heat, potentially making the deck surface more comfortable underfoot.
Planning Your Pool Terrace: Material Quantity and Layout
Accurate material calculation is essential for any decking project. For a hypothetical pool terrace measuring 20 feet by 15 feet, you would need to calculate the total square footage: 20 ft * 15 ft = 300 square feet. PVC decking boards typically come in various lengths, such as 12, 16, or 20 feet, and standard widths, often around 5.5 inches.
To illustrate, if you choose a standard 12-foot length board with a 5.5-inch (0.458 ft) width, each board covers approximately 12 ft * 0.458 ft = 5.496 square feet. For a 300 square foot area, you would theoretically need 300 / 5.496 = 54.59 boards. Always round up to ensure sufficient material, accounting for cuts and potential waste. In this case, you might start by planning for 55-60 boards.
Consider the layout: running boards parallel to the longest dimension often minimizes cuts and waste. However, a diagonal layout can add visual interest but typically requires more material due to increased cutting. Always consult the specific product installation guide for recommended board spacing and fastener requirements, as these can influence the final quantity needed. For any project, it is prudent to order an additional 5-10% for waste and future repairs.
Installation Considerations for Poolside PVC Decking
While PVC decking is designed for wet environments, proper installation is still critical. Ensure the underlying deck frame is sound and provides adequate ventilation. Good airflow beneath the deck helps prevent moisture buildup and supports the long-term integrity of the structure.
Hidden fastening systems are often preferred for PVC decking, providing a clean, fastener-free surface that is comfortable for bare feet. This is particularly desirable around a pool where people will be walking barefoot. Alternatively, face-fastening may be an option, but careful planning for screw placement and color-matched screws is important for aesthetics.
Always adhere to the manufacturer's specific guidelines for board spacing. PVC boards can expand and contract with temperature fluctuations, and proper spacing accommodates this movement, preventing buckling or gapping. This is especially important in climates with significant temperature swings.
Maintenance and Longevity in a Montgomery Climate
One of the primary advantages of PVC decking for a pool terrace is its low maintenance. The advanced capping on Azek and TimberTech Azek boards makes them resistant to common stains and mildew. Regular cleaning with soap and water is typically sufficient to keep the deck looking its best.
In Montgomery's climate, which often includes hot, humid summers, the material's resistance to rot and insect damage is a significant benefit. Unlike wood, PVC does not absorb moisture, which eliminates the conditions necessary for rot and fungal growth. This contributes to the material's potential for long-term performance.
While PVC decking is durable, it's always wise to avoid abrasive cleaners or harsh chemicals, which could damage the surface finish. Refer to the manufacturer's cleaning recommendations to ensure product compatibility and maintain the integrity of your deck.
Before you order
- Confirm the exact dimensions of your pool terrace area.
- Choose a PVC decking line and color that complements your home's exterior and pool area aesthetics.
- Review the specific installation requirements for your chosen PVC decking, including framing, ventilation, and fastener types.
- Calculate material quantities, adding 5-10% for waste and cuts.
- Consider heat-mitigating color options if the deck will receive significant direct sun.
- Plan for proper drainage away from the deck surface.
- Understand the manufacturer's recommended cleaning and maintenance procedures.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.

Questions to help you decide
Is PVC decking slippery when wet?
However, caution should always be exercised on any wet surface, especially around a pool.
Can PVC decking be installed directly on concrete?
PVC decking boards typically require a substructure (joists) for proper support and ventilation, similar to wood or composite decking. Direct installation on a concrete slab without a substructure is generally not recommended as it can hinder drainage and ventilation, potentially leading to issues. Always consult the manufacturer's installation guidelines for specific requirements.
How does PVC decking handle chlorine and pool chemicals?
PVC decking is inherently resistant to moisture and many common chemicals, including those typically used in pool water. However, spills of concentrated chemicals should be cleaned promptly according to manufacturer recommendations.
