Section 2
Step 16 - Backfill
16.1
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.
