Meet TuffBlock - The Revolutionary & Highly Engineered Polymer Alternative to Concrete Deck Blocks

Could a piece of plastic replace traditional concrete footings?

When building a deck, traditionally the builder will dig footings and pour concrete for the foundation. Another method for low profile decks is concrete blocks that can be placed directly on the ground. We have designed and developed a product that makes deck installs quick and easy.

It is called TuffBlock. An instant foundation system made from 100% recycled plastic right here in Australia.

TuffBlock's are more than just a deck foundation, they are a versatile utility block that can be used for an endless number of applications including low profile and raised decks, temporary structures, rooftop decks, sheds, dog kennels, walkways and more.

An individual TuffBlock can support up to 1,700 lbs and break-tested to over 11,000 lbs. TuffBlocks will accept 1.38-1.61 inch or 1.61-1.85 inch joists and bearers as well as 3.5x3.5 inch or 4x4 inch posts. TuffBlock's are the most versatile and easy to use deck foundation systems on the market.

Opinion on using giant screw piles then mounting the Tuff block on top of it? Can I screw through the bottom plastic flange?

These look awesome!! Gonna pick some up for an upcoming project.

[jcarchery]

look cool! do you not stake them in to the ground in anyway after they are leveled an placed? would be worried about them shifting, or is that not an issue after the load is on them?

[bradhenshaw]

Cool product! Great job too on using 100% recycled plastic.

So this thing allows water to escape then could you use standard lumber instead of pressure treated?

No wonder I was straining myself, 41 lbs! How long have these Tuffblocks been around! Got another shed to jack up-

I have only seen these used for low decks. Can these be used for decks for an above ground pool? Posts would be around 4’ high.

I am looking at building a 20'' x 20' deck for a customer and the only length of lumber I can get is 2x6 in 16' length so was looking for some guidance on whether or not I can place two boards end to end on a tuff block allowing me to reach the 20' length and using a Tie Plate to secure them together.

How does it prevent the movement of wood in summer

[Jackman]

What kind of ground prep do you need, you can't just throw on the grass?

[archieanderson]

Now I know what Im going to be using in a we area and that my friends is Tuff block.

[Daddyoftam]

What happens if you nest these to level your deck? Is the strength compromised?

[November_Charlie_Red]

Would these be good for the corner pieces for a dirt greenhouse?

[MariaLuna-jluu]

we need the weight too for many reasons!!!

[Bonkatronicks]

says height is 90mil is that with the wood inside or is that how big the thing is?

[jackgray]

Why can't I buy these in the UK ?

[moods]

Ok. I looked up the price. Concrete Deck Blocks = $9.68. Tuffblock = $8.95. This is at LOWES. And in Home Depot, Concrete Deck Blocks are one penny more than Lowes concrete deck blocks.
My only Question..mine are in Dirt...for a floating deck... are they going to slide around in the packed gravel I use to level everything? Is that why you recommend using heavy Concrete deck blocks at the ends ? I'm a Veteran.. have a bad back.. this will allow me to build the deck vs have to pay someone.. which I really cannot afford.

[waheedmalik]

You put them straight on grass???!!! And you're saying they won't sink once there is weight on top? Should there not be a solid base?

[timsmith]

So a concrete footing under my raise deck went sideways today after heavy rain… It was like 4 inches underground. Can I buy a new post and use one of these as a replacement to the concrete post? It was just the 4 x 4 sitting on top of the concrete… I know it’s not up to standard for today but the thing was built 30 years ago.
