BOTTOM PREPARATION
RESETTING POOL FORM DIMENSIONS
Once the footing has been poured, check the depth in various sections of the pool bottom
(including the hopper/deep end) in relation to the top of the wall. If the excavator has worked
carefully, the pool floor should be close to the exact depth of excavation; leaving only a small
amount of hand trimming to be necessary. Remember, the depths may be up to 2" deeper than
the dig measurements on the dig spec but may not be less than the dimensions shown on the
dig spec o
r over the 2” deeper mark. Extra depth will end up helping with the liner fit, especially
when installing the liner in temperatures above 85°F. The final sizing of the pool bottom
determines the smooth future appearance of the liner in the finished pool.
Moving forward, disregard the “excavation dimensions” of the hopper as you will need to
reference the “finished dimensions” on your dig spec from h
ere on in. The finished dimensions
allow for 1 to 2" of sand mix or vermiculite pool base and provide an accurate guide for your
troweller when finishing the pool bottom.
The hopper dimensions are intentionally 2" less than the excavation dimensions. This is to allow
for 2" of pool floor material (sand or vermiculite mix). Remember that the finished depth
shown on the dig spec is from the liner track (top of the wall panel) to the top of where the
sand/vermiculite bottom will be.
IMPORTANT! If you are installing a cantilever deck using foam forms you must
skip to step “
Backfilling the Pool
” on
page 50. Only
return to “
Bottom
Preparation
” (below) after completing the deck. (Your cantilever de
ck using
foam forms must be complete before installing your pool
’s
liner so refer to page
30 if needed)
Optional: If you are using bullnose coping or flat track cantilever coping with
bricks or stones you may also skip to step
“Backfilling the Pool” on pa
ge 50.
