Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

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.

Your deck may pop, and your neighbor’s deck may not for a number of reasons. Whether or not a deck pops will depend on how it was made, the conditions it’s exposed to, and the materials. Improper spacing is a common reason for increased pressure between deck boards. Moisture penetration is another.

In most cases, your deck will need some form of deck footing to hold it in place, preventing moisture from rotting your wood and decreasing your deck’s lifespan. Concrete deck blocks are the most common type of footing for floating decks. Some homeowners use ground-level deck footings. For added security, consider digging and laying your ground-level footings below ground.
