Since the inception of Deck Blocks in 1988 in the USA, instant foundation blocks have been the preferred method for creating
a strong and stable foundation for many professional & DIY projects worldwide. The concept has literally revolutionised the
way we look at deck & raised platform construction, with millions of projects completed each year using the system.
TuffBlock’s are made of high strength closed loop recycled polyolen 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.
An individual TuffBlock can support over 770 kgs (1,700 lbs) and weighs only 680 grams (1½ lbs). Designed to accept
35-47mm (2” x 4”, 2” x 6”, 2” x 8”) Joists and 90 x 90mm - 100 x 100mm (4” x 4”) Posts, TuffBlocks truely are the
lightest, most versatile and easy to use deck foundation system on the market.
Unique to the TuffBlock is the ability for low level decking, it is now possible to build a deck as low as 165mm (6½ inches)
without the need for digging. No more ugly concrete blocks in your yard. The slimline prole and satin black nish means
a TuffBlock easily blends into the landscape and surrounds.
TuffBlocks are more than just a deck foundation, they are a versatile utility block that can be used for an endless number
of applications.
TuffBlocks are not designed for use in structures elevated more than 1 metre (39 inches) from the ground and should be installed on stable ground (see www.buildtuff.com for more
details). As always, it is recommended to check your local building guidelines before starting any construction - we always suggest you get the thumbs up before starting your project.
The general rule of thumb is to space joists at 450mm (18 inches) centers
(maximum). This spacing depends on your decking or platform material so check
with your timber supplier for project specic recommendations. Joists can sit directly
on TuffBlocks (e.g. TuffBlock - joists - decking/platform) or on top of a substructure
(e.g. TuffBlock - bearers - joists - decking/platform).
