Deck footings make it possible to stand sturdy on your outdoor deck. Make sure you understand the code requirements for footing structures in your area. Wet the pier blocks before you set them in place, as this will keep them from absorbing moisture from the concrete. Put the pier blocks on top of the semi set concrete, and level them. Let that concrete dry overnight to insure a nice set of your
. footings. Once dry, cover them with dirt, and let the building begin for the new deck. More information may be found at http://www.ehow.com/how_15995_install-footings-deck.html.
