STEP 5
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 4
POSITION AND LEVEL REMAINING CORNER TUFFBLOCK PIERS.
Next, remove the rst oor joist closest to the structure.
Temporarily position a trim board on top of the rst 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.
