Step 3: Level the Furthest Point

Begin by positioning the two remaining corner Dek-Block® piers. Measure from the house out to the outside edge of the groove in the block. (For example: If the deck will be 10 feet deep, position the block so that the outside edge of the groove is 10 feet from the HOUSE. Do NOT use the the first row of blocks as a measuring reference.) Use the same width between the Dek-Block® piers as the first row.

Next, remove the first support board closest to the house. Temporarily position a 2"x6" end board on top of the first row's 4"x4" post or block, and extend it to the outside corner block. 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 on the Dek-Block® pier. Cut a 4"x4" post to length and position the 2"x6" end board on top. Verify the 2"x6" end board is level. When level, remove the end board and repeat for opposite side.
