Answer This Question

A:  I placed each on a 12”x12” paver and would use 6 for your size.

    A:  I put these directly on soil that I had leveled and had them 16" on center - way easier to use than the old concrete block style

    by|Feb 10, 2022

      A:  In accordance with the manufacturer website, all I did was level the dirt underneath the block.  These take place of traditional footings. So the number needed depends on the design of your deck.

        A:  You can put the blocks on solid undisturbed soil!

        by|Feb 11, 2022

          A:  Simply compact the ground and place appropriately 1" of sand on the top of the foot area and recompact. The footer sets on the prepared area.8 foot on center is the minimum if you use 2x10.

                Tuffblock
                Very easy to work with. We used Tuffblock to build a low deck over existing concrete. Looks great

                      I used these to make a 7 x 12 foot floating deck by my bocce court. They work great! Very stable and with much less digging and hassle than traditional methods. Because of their low profile the deck is very close to the ground, which works out great!
