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
You can use TEAK sealer, which is a waxy brush-on liquid that is a sealer for end grains and can be used to water -proof. It does change the wood color to a richer darker color. I used this on my cedar posts which support my Pergola which are inserted into 4 of these blocks (blocks were painted with water-proofing white paint). No problems to date!!

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.

11-1/2 in. x 8 in. x 11-1/2 in. Concrete Block is rated 4.3 out of 5 by 59.
Rated 1 out of 5 by from If the blocks actually looked like those in the picture,... If the blocks actually looked like those in the picture, you would have had a 5 star. The fact is, the inside of the structure is so uneven that we had to chip out concrete to get the 4 x 4's to a point where they would settle into the block. They don't have a smooth inner finish. It looked like someone dumped leftover concrete into the center of each one. Very disappointing!

Rated 2 out of 5 by from Check Carefully - Poor Quality Control My store had two pallets of these blocks that could not safely be used due to poor quality control. The post would not properly rest on the block Check the ones at your store carefully before buying to make sure that they are shaped properly and do not require any modifications. They should look just like what is shown in the picture.
