INSTALLATION GUIDE
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. The outside edge of the nished deck will
extend out past the center of the TuffBlock piers by 350mm (14 inches) on both sides.
Don’t spend an excessive amount of time leveling the TuffBlock piers. The block can be leveled
with only your eye. Any slight difference will be made up with the post. However, you want to make
sure the TuffBlock piers are sitting FLAT. You do not want any rocking of the piers on the ground.
STEP 2
LEVEL THE FLOOR JOIST.
Locate the highest TuffBlock pier. Position a oor joist in or above this rst block to your desired
height. If the entire deck will be elevated, you will need to have a post in the rst TuffBlock.
Place a oor joist in the slot of the TuffBlock pier or on the post and extend over the second corner
TuffBlock pier. Now, using a level on top of the oor joist, measure the distance from the top of the
oor joist to the bottom of the pocket in the TuffBlock pier. Next cut a post to length allowing for
B-B and position the oor joist on top. Make sure to verify that the oor joist is level. Do not attach
the oor joist to the post yet.
If the entire deck is to be elevated you will rst need to establish the height of the rst post, once
this is completed continue following the directions above.
STEP 3
POSITION AND LEVEL REMAINING CORNER TUFFBLOCK PIERS.
If building off an existing structure, measure from the
structure to the outside edge of the post. (For example: If
the deck will be 3 metres / 10 feet deep, position the block
so that the outside edge of the post is 3 metres / 10 feet
from the structure.) Do NOT use the the rst row of blocks
as a measuring reference. Use the same width between the
TuffBlock piers as the rst row.
