Step 2: Level the support board.

Locate the highest corner Dek-Block® pier. Position a 2"x6" support board in or above this first block to your desired height. If the entire floor will be elevated, you will need to have a 4"x4" post in the first block.

If the entire floor is elevated, you will need to find the height of the first 4"x4" post to determine your starting point. Start by determining your reference point for the top of the floor surface, this may be a point on the siding of the house. From this mark, hold a level out over the block and measure from the bottom of the level to the pocket of the block. From this measurement, subtract the thickness of the surface planks and the thickness of the support board (3/4" + 5 1/2" = 6 1/4""). Cut the first 4"x4" post at this measurement and continue with the directions.

Place a 2"x6" support board in the slot of the Dek-Block® pier or on the 4"x4" post, and extend over the second corner Dek-Block® pier. Using a level on top of the 2"x6" support board, measure the distance from the bottom of the 2"x6" support board to the bottom of the pocket in the Dek-Block® pier. Cut a 4"x4" post to length and position the 2"x6" support board on top. Verify that the 2"x6" support board is level. But don't attach 2"x6" support board to the 4"x4" post yet.
