Deck Footings - The Importance of Support Deck Footings - The Importance of Support

Deck footings are an extremely important aspect of your deck. Here’s why:

Support

Footing is designed to split the weight load of the deck over a larger area. Without the footings, your deck may sink, warp or crack under heavy weight. The more footings your deck has, the less weight each one has to bear. This is something to keep in mind when designing your deck.

Evenness

As the temperature of the ground changes each year, the deck can expand and change size. It may not be a big change, but it’s enough to cause the deck to lose some of it’s evenness. To prevent this, deck footings are built to be resistant to frost, so you will only have to worry about the lumber on the actual deck— not the footing itself. It’s important, however, to make sure your footings extend beyond the frost line to avoid damage to the footing.

Safety

Even if you only have a small deck, you need footings for safety. Though it seems like setting a small deck on a concrete slab is good enough, the reality is that it’s just not safe. No matter how small the deck is, the concrete slab would have to carry weight that is much heavier than it’s own size. You would still run the risk of the deck crushing or cracking the ground or concrete beneath it. To prevent unnecessary repair costs, build your deck with footings.
