Step 4: Level the opposite side.

Place the two remaining corner Dek-Block® piers. Using the same width between Deck-Block® piers as the first row, measure using the dimensions on the plan.

Remove the first support board. Temporarily position a 2"x6" end board on top of the first row's 4"x4" post or block, and extend to the opposite corner block. Then, using a level on top of the 2"x6" end board, measure the distance from the bottom of the 2"x6" end board to the bottom of the pocket of the Dek-Block® pier. Cut a 4"x4" post to length and position the 2"x6" end board on top. Verify that the 2"x6" end board is level. When level, remove the end board and repeat for the opposite side.
