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.

Difficult to level and keep in place.
Hard to use because they move around as you put more under the same joist. They need to add a staking system to them.

These are amazing. Super easy to use, and great for building a level platform on uneven ground.

Easy to use
Would RecommendBought this since the concrete parts were not available. They are easy to use and weigh less than the concrete parts. Hopefully the code enforcement inspectors will pass them when they do their inspections.

I highly recommend
Would RecommendThis product helped me with my small outdoor gazebo. I highly recommend I tried the Camo competitor version and I had to return bc of poor drainage. The Tuffblock worked out much better. Thank you!

I haven't installed these yet but after seeing the actual size of them I can't think that they will really support what they claim they can. I will have to have something with a bigger foot imprint for my needs.
