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.

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.

Great on slab pier.
Would RecommendI was redoing a old deck that was on top of a slab. I liked the fact that they were low profile and light weight.

Price is too high but they work ok
It is dumb that they charge 12 bucks for a plastic block. It is clearly price gouging as the product is very cheap to make. They should be less expensive than concrete blocks, not more. They work but are priced way too high for what they are.
An easier way to support 4x4 post
Would RecommendVery impressed with the product a lot easier than other methods of supporting a long ramp and a deck at dock height for access to access a building.

Easy to work with and better than concrete
Would RecommendThe price was a little high. But for the convenience of being lightweight compared to a concrete block is worth the difference
