Section 1
Step 13 - Backfill
13.1
Ensure all electrical bonding required in your area is
completed before backfilling the pool. This is a good time
to add any concrete foundation forms or perforated drain
pipes, if they will be used.
IMPORTANT:
Before any backfilling is started, the pool
water level must exceed the height of the surrounding
backfill required, as in examples 13.1 and 13.2. Failure to
do so will put excessive inward pressure on the pool
panels which may cause irreversible damage, and may
void your warranty.
Crushed stone or gravel aggregate,
3/8”
to 3/4
”
in
diameter
is the recommended backfill material. Backfill may be
placed directly against the pool wall. Do not use expansive
soils such as clay since this type of soil will place additional
stress on the pool and not allow for proper drainage away
from the surrounding area.
Only compact the backfill material manually by hand. Do
not use heavy machinery, especially around the skimmer
and plumbing fittings.
