TuffBlock is a lightweight yet heavy-duty alternative to traditional, heavy concrete deck blocks. Stackable and easy to transport, one trip to the store and off you go carrying out the blocks you need for your free-standing deck project! TuffBlocks weigh only 1.5 lbs. each (26 times lighter than concrete blocks), but are load-tested to support over 1700 lbs. and have been break-tested to over 11,000 lbs! TuffBlock floating foundation system allows for easy transport as well as a simple installation process. Designed not just for freestanding decks, but sheds, walkways, dog houses and various other exterior applications, TuffBlock brings the versatility of traditional concrete blocks without the chipping, cracking and unnecessary weight and hassle. TuffBlock is designed to accept 2 In x 4 In, 2 In x 6 In and 2 In x 8 In joists and 4 In x 4 In posts, making it an ideal replacement for outdated heavy concrete blocks. Unlike most concrete blocks, there is no need to cut or chisel TuffBlocks in order to fit your post or joist—just lay your TuffBlocks, set your posts or joists and compete your project! TuffBlocks are UV-stabilized & climate-proof—they won’t crack, corrode, or absorb water in any environment. Made in the USA from recycled polyolefin material with an ultra-high UV rating, TuffBlocks are designed with a ventilated underside to prevent moisture buildup and termites. Additionally, the TuffBlock system allows for a deck that is 5.5 inches low without the need for digging, creating the lowest profile possible.
