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.

Game Changer!!

Would Recommend

I cannot believe how easy these were to use and how strong they are once my deck was completed.

Great foundation base

Would Recommend

Installed on 4 inches of gravel, used a spirit level to ensure they were flat before installing hardware. Worked great. The sloped sides allow water to run off without pooling, ensuring longevity.

Works great for decks

Would Recommend

I used Tuffblocks for a ground level deck and found them to be really great to work with. I am a homeowner and was able to adjust the height for level on the fly with Tuffblocks, something I could not do if I had to set concrete or pier blocks. Saved me time and effort so worth the cost. Very happy with this product.

Foot Post

Easy to use, and easily fit the post. No need to chisel away any out of place cement. Plus, a whole lot lighter…
