ABOUT TUFFBLOCK 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 polyolefin material with an ultra high UV rating.

ULTRA-LOW PROFILE DECKS Floating foundation systems have always been flawed when it comes to low profile decking. Due to TuffBlock’s extremely low design, decks as low as 165mm (6½ inches) are now a possibility. RAISED DECKS Tuffblock’s allow for use with 90 x 90mm - 100 x 100mm (4” x 4”) Posts, allowing your deck to be elevated to any height desired.* VARIABLE HEIGHT DECKS Got a sloping or uneven surface? Due to TuffBlock’s incredible adaptability variable height decks are a breeze to install.
PRECAUTIONS HOW TO POSITION TUFFBLOCKS ON AN UNEVEN SURFACE In the event of placing a TuffBlock on uneven surface, please note that in no circumstances are you to ‘build up’ the footing beneath the TuffBlock. In every instance the underneath footing must be dug out in order for the TuffBlock to be level ground prior to commencing your project.
I N S TA N T F O U N D AT I O N S Y S T E M STEP BY STEP INSTALLATION GUIDE The following illustrations are of an example deck build approximately 3 x 3 metres on a sloping surface using the following materials: TuffBlocks 90 x 90mm Posts 45 x 90mm Joists 90 x 18mm Decking boards Hardware (Nails, screws, brackets etc.
STEP 1 PLACE THE TWO CORNER TUFFBLOCK PIERS CLOSEST TO AN EXISTING STRUCTURE. Place the TuffBlocks directly on the ground. If the ground is sloped, remove top soil from directly underneath the block until the block sits level. If the deck is going to be an extension of an existing structure, then the blocks should be as close to the structure as possible. Using the plan on the previous page, ensure the blocks are correctly spaced.
STEP 4 POSITION AND LEVEL REMAINING CORNER TUFFBLOCK PIERS. Next, remove the first floor joist closest to the structure. Temporarily position a trim board on top of the first row’s post or block, and extend it to the outside corner block. Using a level on top of the trim board, measure the distance from the top of the trim board to the bottom of the pocket on the TuffBlock pier. Cut a post to length. Verify the trim board is level. When level, remove the trim board and repeat for opposite the side.
STEP 6 ATTACH REMAINING FLOOR JOISTS. Position and attach the remaining floor joists to the trim boards using two 75mm (3 inches) counter sunk batten screws to attach the floor joist to the trim board. STEP 7 POSITION REMAINING TUFFBLOCK PIERS. Using the frame as a guide, position the remaining TuffBlock piers directly beneath the frame. The blocks on the perimeter of the deck should be 300mm (12 inches) in from each end.
STEP 8 FILL THE REMAINING POSTS. Cut posts to length and position them between the floor joist and the TuffBlock pier. Repeat this step until all posts are cut and positioned. Next, secure all floor joists and posts using two 75mm (3 inches) counter sunk batten screws. STEP 9 ATTACH THE DECKING. Starting from one side of the deck, attach the first decking board so it’s flush to the edge of the deck. The decking board will overhang the first floor joist closest to the existing structure.
