Step 2: Positioning Dek-Block® Piers and Leveling Posts

Since every pool is unique, the location of the first Dek-Block® pier will vary for your specific pool size and manufacturer. Determine where the first Support Frame will be located, then position the first four Dek-Block® piers for this Support Frame. The most convenient location to begin is a few feet to the left or right of the pool's filter or pump. The Support Frame should be positioned 1-2 inches back (out) from the pool's metal coping. (The Support Frame needs to be away (out) from the pool's coping in order to attach the decking later.) The Dek-Block® piers should be positioned in reference to its location along the Support Frame. Each Dek-Block® pier should be placed on level ground, six inches* in from the end of each Support Frame piece D and E, as shown in Diagram 7 (* verify this dimension on the plan – some plans may vary slightly). Once the first four Dek-Block® piers are positioned, place a 4"x4" post in the post pocket of one of the Dek-Block® piers and hold plumb (vertically level).

Using a level and the pool's metal coping as a guide, mark a line level with the top of the pool's coping, as shown in Diagram 8. From this line, subtract the following 4 items:

1. The thickness of the pool's coping.
2. 1/2" for water drainage and air flow between the decking and the pool's coping.
3. The thickness of the surface boards. 1 1/2" for 2"x6" decking and 1" for 5/4"x6" or composite decking.
4. 5 1/2" for the thickness of the 2"x6" support frame.

Cut the 4"x4" post to length and repeat this step for all four - 4"x4" posts of the first Support Frame.
