2. THE FOUNDATION
(continued)
2.11 Measure the diameter from the center of the pool to
the interior of the grooves on the rail on each side of the
bottom plates. The distance should equal the radius of
your pool. When the measurement is good, plant a nail or
8” rod on the exterior center of each bottom plate so that
they can stay in place.

2.12 Measure between each opposite bottom plate to
make sure your pool is a perfect circle. You must not miss
or skip this step under any circumstances because an oval
pool could cause future problems, and pool can even
burst in time.
Measure between each opposite bottom
plate to ensure a perfect circle.
2.10 Spread the rock dust in center of the pool foundation
so that level is maintained with the exterior compacted
rock dust. Compacting this part will be done in a subse-
quent step just prior to installing the liner.
