These are awesome
I built a 12X12 foot deck by myself (I am a 110 pound female) with these blocks. No way I could have done it with the concrete deck blocks and I did not want to dig too much. I only wanted my deck 8 inches off the ground. Concrete blocks are heavy, bulky and tall. These are awesome and so tough.

Tuff and Easy
Never used Tuff Block before so I decided to purchase 36 of them to build a 20x10 floating ground level deck! So far my experience has been positive - I will be laying the remaining blocks over the next week!

So far, so good!!
Got these for a porch addition and they were wonderfully easy to use!! Very versatile and porch has already been put to the test and they have done a great job!! When we add additional footage we will use them again!!

That’s two decks with the TuffBlocks
That’s two decks with the TuffBlocks. the one on the right, 10x12 done four years ago and the Christmas 2020 abutting left 10x8.5x7x9’ special cut deck, supported entirely with these superbly designed, super tuff no digging support. If you are serious about ground level, NO Piling under structure,you GOTTA consider these TuffBlocks. Chas ... show more

Makes deck building easier and lower profile
These are a life saver and complete game changer. Used decks.com to get the specs for my deck and was very happy with these in our space. Our deck is a lower profile which I’m happy with and these were uncomplicated to move around and change up

Light weight and sturdy beats concrete blocks.
The low profile works and light weight well for many applications While keeping the wood off of the ground to reduce the probability of rot.
