Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

You typically don’t need a railing and handrails on a deck that’s less than 30 inches from the ground. However, consider adding them regardless. Railings provide additional safety for you and your guests who use your deck—plus, railings give the deck a more finished look than it would have without them.

The best paver for your pool deck depends on your budget, style, and how much maintenance you’re willing to invest. Granite is one of the best low-cost pavers for pool decks. It’s very slip-resistant and durable, too, making it a top pick. Travertine is a high-quality material that resists freeze-thaw cycles, looks stunning, and won’t get hot in the summer. The only downside to travertine is that it costs more than granite.
