TuffBlock is designed to replace heavy concrete blocks used in the floating foundation deck block system trusted for over 35 years!
An individual TuffBlock has been designed to support over 1,700 lbs and has been successfully tested to support over
11,000 lbs, yet 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 polyolefine 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 product 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 existing landscape .
