Description

The TuffBlock Instant Foundation System is a lightweight deck foundation alternative to concrete. It consists of multiple floating deck blocks that sit on top of the ground and accept pieces of wood to construct decks, garden sheds, landings, pathways, raised walkways, cubby houses, dog shelters and more. The TuffBlock’s are made from recycled polyolefin material with an ultra high UV rating. They are designed with a ventilated underside to prevent moisture buildup and termites. The TuffBlock system is the only block product that can be secured to the post or bearer to provide extra stability. Each TuffBlock can support up to 1,700 pounds and weighs only 1.5 pounds. They are designed to accept 2” x 4”, 2” x 6”, 2” x 8” Joists and 4” x 4” Posts. The TuffBlock system is unique because it allows you to build a deck that is 5.5 inches low without the need for digging.

  • Great easy product
Worked great for a seasonal campsite that we built a deck for!

  • Lowes sells for $8.99. Great product!
Great product. Easy to use. $8.99 at Lowes

  • Seem to work well
The openings are different sizes, none of which are ideal for the actual measurements of a 2x4. For this I take off one star. For the 7'x7' shed platform I built, these seem to work great. They're also much easier to work with than the concrete version of the same thing.
