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.

Just what you need for a floating deck project.
Much better for building a floating deck than the concrete counterpart. Easy to install and the low profile means less digging than the heavier concrete blocks

Lighter than using pavers
What I like about the Tuff bBock product it is light weight. The label was big to read and understand. It was easy for a one person job to move around. Anyone over age of 60 can manage the product.
