How do I stop my deck from swaying?

How do you brace a deck underneath?
To brace the underside of your deck, all you need to do is fasten a pressure-treated 2×4 diagonally from corner to corner on an angle. You’ll need to drive in two 16d nails at every point in which the 2×4 meets the deck’s joists. If the underside of your deck is too large to use a single 2×4, use two 2x4s.
How do you reinforce a wobbly deck?
To stiffen the deck, go underneath and install a row of 2×8 blocks down the center, perpendicular to the joists. Stagger them with enough room to nail or screw them in place through the end grain, then fasten the treated 2x4s to the underside of the joists so they run from corner to corner, forming an X.
Why does my deck shake?
People walking on the deck parallel to the house will cause a sideways force, and the deck will shake. Often the decking acts as enough of a diaphragm to stiffen the deck itself against these forces. Another thing that keeps most decks from moving too much is the length of their posts, which is usually 4 ft. or less.
Do freestanding decks need footings?
According to the main code provision for footings, the only requirement for building a deck that is freestanding is that it must have a minimum footing depth of 12 inches below the undisturbed ground surface. There is no need to extend a footing below the frost line, as is required for standard decks.
How do you support a deck without posts?
Instead of using footings, adding a level of gravel will give you the drainage aspect you are looking for. You can then add a frame of wood that anchors in concrete blocks that sit in the gravel, creating your new deck. Concrete blocks won’t rot, making them an ideal option for those who don’t want to use wood.
How do you reinforce an existing deck?

What angle should a gate brace be?

Should I put a vapor barrier under my deck?
In a crawlspace under a house, the air moisture can easily be dominated by the soil moisture and is one reason that a vapor barrier is used. The tar paper over the joists and under the decking is a VERY GOOD idea and it is one of the best things that can be done to prevent decay of the joists.
How do you build a deck without digging holes?
If you’re ready to start planning, there are two great options to build a deck without digging any holes: surface deck blocks and deck foot anchors.

Can I use deck pier blocks instead of footings?
Pier blocks can be used instead of footings for a ground-level deck not requiring permits. Any decks higher than 24” require concrete piles 10” in diameter and 48” below grade. These footing size requirements are to ensure enough soil bearing to prevent the joist from sinking in the ground.
