What Customers Are Saying
Customers overwhelmingly praise these deck supports for their ease of installation, lightweight design, and superior durability. Most highlight how simple setup is—simply level the ground and place blocks with no digging, tools, or expertise required. Many note they can carry stacks of 10 with ease, making solo projects manageable. Reviewers consistently confirm the blocks securely support 4x4 posts and beams for decks, sheds, and ground-level structures. Made from recycled plastic, they resist cracking and shifting under load. A few mention cost concerns, but most consider them an excellent investment for convenience and reliability.

Easy to use! Made the leveling of my shed base very easy. A few dollars more than the cinder block versions without having to carry them.

Easy Installation
Would RecommendI found the TuffBlock to be easy to install and appears to be quite durable. I used TuffBlock to level the 4 corners of my storage building with 4" x 4" pressure treated posts. There is nothing about it that I did not like, although it is a little bit expensive. But, with a 25-year warranty, it is well worth it.

No concrete needed
Would RecommendI loved these easy to use and they made leveling a breeze... We are building a large shed. No mess with concrete was a big plus for us.

Great product
Would RecommendThese things are great. I had an uneven piece of concrete to build a deck on and used about 16 of these. Able to cut each 4x4 post to length to level deck.
