Instant Foundation System by TuffBlock
Highly-engineered concrete block replacement
The average deck is 12' x 16' (20 TuffBlocks are needed for a deck this size)
Using America’s most trusted floating foundation system for over 35 years
An individual TuffBlock can support over 1,700 lbs. and weighs only 1½ lbs. Designed to accept 2” x 4”, 2” x 6”, 2” x 8” Joists and 4” x 4” Posts, TuffBlocks truly are the lightest, most versatile and easy to use deck foundation system on the market.
TuffBlock’s are made of high-strength, closed-loop recycled polyolefin material with an ultra-high UV rating. Designed with a ventilated underside to prevent moisture buildup and deter termites. TuffBlock’s are the only block products that are able to be secured to the post/bearer for extra stability.
Unique to the TuffBlock is the ability for low-level decking, it is now possible to build a deck as low as 6½” without the need for digging.
No more ugly concrete blocks in your yard. The slimline profile and satin black finish means a TuffBlock easily blends into the landscape and surrounds.

TuffBlocks have been engineered for structures up to 36" above ground. Having said this, many people have built structures higher than this using the composite foundation method (TuffBlocks in combination with concrete-in-ground footings). We recommend that you consult with a qualified builder or engineer regarding your project.
