9 in. x 9 in. Composite Deck Block 4 in. Center (4-Pack)

The biggest benefit of these blocks is the weight. They are by far substantially lighter than any concrete footing block at around a pound each and these wont crack or crumble during extreme cold freezes. Kinda like why did it take so long for a product like this to hit the shelves!? You can use 2 by lumber or 4x4 depending on your design. The center opening is 3-1/2" square so it is taking into actual milled lumber sizes will fit snug as it should. There was a informative instruction booklet I received with my blocks detailing the requirements for the blocks and layout , I really wish they would add this to the website or item page because It would have been very helpful prior to any layout. So the blocks stand 2" tall- with about 1-1/2 being the lip that holds in the wood, and about a half inch being the platform that the wood sits on. I was not thrilled about the block only raising the wood a half inch off the ground because I live in heavily wooded lot- where leaves will gather around my footings every fall. We came up with a solution of attaching a foot of fencing on the edge of the deck as screening to keep the debris from blowing under and away from the footings. I will be adding rock around the blocks to ensure good drainage. I would still recommend these for a ground level deck.

We liked these fine and were happy with the results but our property had to have a county inspection and these were one of the items listed causing us to fail. Now we are having to jack up our new deck and replace.

These are excellent, so easy cause unlike concrete blocks, they aren't heavy. Hold the wood tighter than a concrete block also. Wish id discovered them at the start of my project, not the end.
