Building a small deck around an above ground pool transforms a simple backyard feature into a functional outdoor living space. A well-constructed deck provides a stable, attractive surface for sunbathing, simplifies pool entry and exit, and creates a defined area for lounging or entertaining. This project requires careful planning, especially regarding pool stability and local building codes, but the result is a significant upgrade to your backyard oasis.
Planning Your Above Ground Pool Deck
The first step is to assess your site and pool structure. You must confirm that your above ground pool walls are rigid and will not collapse under the new weight and movement of a deck. Measure the pool's diameter and decide on the deck's overhang, typically 12 to 24 inches beyond the pool wall for a comfortable barrier edge. Sketch a simple plan, noting the location of stairs, access points, and any underground utilities before breaking ground.
Material Choices and Considerations
Choosing the right materials is critical for a deck that will endure the elements and the unique stresses of a pool environment. Pressure-treated lumber is a cost-effective and popular choice for the main structure due to its resistance to rot and insects. For the deck surface, composite decking offers low-maintenance benefits and does not get as hot as wood in direct sunlight, while capped PVC provides a premium, splinter-free option with exceptional durability.
Structural Support and Footings
Support is the most crucial aspect of an above ground pool deck. The weight of the deck, furniture, and people requires robust posts anchored deep into the ground. You will typically need to dig holes for concrete footings at least 4 to 6 feet deep, or use surface-mounted post bases if local regulations prohibit deep digging. The support posts must be attached securely to the top ledge of the pool wall to prevent lateral movement and ensure the entire structure remains level and secure.
| Material | Best For | Key Benefit |
|---|---|---|
| Pressure-Treated Lumber | Budget-conscious framing | Cost-effective and structurally strong |
| Composite Decking | Low-maintenance surface | Doesn't require staining or sealing |
| Galvanized Hardware | All structural connections | Resists rust and corrosion from pool moisture |
Building the Frame and Installing Decking
Begin by constructing the frame directly on the top ledge of the pool wall, using L-brackets or custom supports to distribute the load. Ensure the frame is perfectly square and level, as this foundation determines the final alignment of the entire deck. Once the perimeter is secure, install additional joists at 16-inch centers running from the pool wall to the outer edge of the deck. With the frame complete, you can lay the decking boards, starting from the pool wall and working outward, using hidden fasteners or coated screws for a clean, finished look.
Adding Safety Features and Finishing Touches
Safety must be a priority when designing a pool deck. Install a sturdy handrail on at least one side of any stairs to provide secure footing when entering and exiting the pool. Consider adding a small gap between deck boards to allow for water drainage and to prevent slippery surfaces. Finally, use a quality exterior-grade stain or sealant to protect the wood from UV damage and chlorinated water, ensuring your deck remains beautiful and safe for years to come.
