Questions & Answers

How do you keep the concrete from rotting the wood?

How do you keep the concrete from rotting the wood? Concrete wicks water and wood absorbs it.
Asked by: Ron
to increase the life of the posts I have seen a roofing shingle used under. it will stay in place without rotting and prevent direct contact. you should still be using pressure treated lumber, thats not a substitute for untreated lumber. also keep in mind with the installation being above ground- it receives good air flow allowing the post to dry quicker than if burried.

can these be used to support a deck?

I have a yard that is very rooty, roots everywhere! Very hard to dig and not get over run by roots. I am looking to build a 8' X 16' deck for my mothers mobile home.
Asked by: trainwreck
Absolutely used as deck support. You just to level the base, no digging in required. a dimensional 4 x 4, which is actually, 3.5 x 3.5, is what fits. I would space them no further than 8 feet apart, depending on your design. Height is not an issue, you just cut posts to your level. I also run a 2 x 4 from under the the joist to the top of the block, to give extra support to the joist.
