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.

Great support for floating deck builds
Would RecommendThese deck support blocks worked really well for my floating deck project. Lightweight but sturdy, easy to position, and helped speed up the installation process. Worked great with 2x8 framing and provided a solid, level foundation. Definitely a good alternative to pouring concrete footers for smaller decks.

Faster and lighter than digging.
Would RecommendThis was my first time using a no-dig foundation for a free-standing deck. I've done many concrete foundations for decks, sheds, and small houses. This was easier on my long-retired, creaky bones and complaining muscles. The deck is strong and stable. I don't see any problems in the future. I strongly recommend these Tuff-blocks.

God but pricey
Would RecommendEasy install and high height capacity. Quite pricey for what it is. Concrete blocks are way cheaper but take more labor to move around and install.

Super easy quick deck or patio base
Would RecommendSuper easy to use they fit a treated 4x4 super snug love how you can use 4x4 on one end and be level on the the other end. Just remember when using gravel that 4x4 make them more inset than if the joist is directly in the groove. There is 2 labeled 1&2 different widths.
