Fiberglass Pool Installation
refers to the process of fiberglass composite pool
shell setting into the ground. The process of installation doesn't reffer to the actual pool construction since the pool shell comes in pre-fabricated and ready to install composite unit.
Digging the hole
By using dig diagram
provided by each pool manufacturer
the pool installation crew will establish the proper elevation of the surface for a future installed pool, mark the ground for a dig and will excavate a hole with 6 inch over-dig
on each side. The depth of the hole should be 4 inches deeper than the actual pool depth for a bottom pad.
Preparing the hole's bottom pad
The bottom of the hole must be prepared for a pool installation by using aggregates
suggested by each manufacturer
for their pool installations. Bottom pad
must be compacted and leveled for the pool. The process of leveling the bottom pad
can be tricky and might require several attempts of getting the pool shell
in the ground.
Sump system construction
Before pool is in the ground the pool installer
should build special sump system
for possible dewatering
from under the pool and for hydro pressure relief
purposes. This system will help to keep the fiberglass pool
from experiencing a stress from the possible water table
and from the ground waters
Under the ideal circumstances the pool shell
should be outfitted with lights
and plumbed while it's still sitting on the ground before installation.
Pool shell installationShell
should be lowered into the ground with crane, larger excavation machine or articulated forklift or material loader. Once the pool shell is sitting in the ground the level must be checked with the laser instruments to assure the proper installation. According to the industry standards the shell could be out of perfect level for not more than 1/2
of an inch. Depending on the pool shell
quality some perfect leveling might not be possible.
Once pool is in the hole and leveled it is ready for a plumbing connections to the pool filter
equipment. The usual size of the line pipes are 1.5 to 2 inches in diameter. Usual plumbing components
of the fiberglass pool
are the main drains
, return lines
, therapeutic jets
, deck jets
, wall jets
, and water bubblers
Simultaneously with plumbing the pool lines electrical wiring should be completed to the pool lights
. Proper conduits and line securities must provide. Some pool lights (low Voltage LED lights) don’t require electrical grounding, and some will. Proper electrical grounding must be installed according to the local codes.
The backfill process might be very trick as of each pool brand might have its own specifics that only come with the experience installing that particular brand. The backfill
is the gradual process of filling up the whole around the pool as the water progresses filling the pool. By early water fill extending the level of the backfill
outside of the pool the walls could bulge in, or the other way around, by to rapid backfill
without the internal pressure of the water, the walls could bulge out. The same is related to the top coping if the pool shell has been backfilled incorrectly. It is not only an esthetical issue, the improper result can create a tension in fiberglass and overtime the pool can endure a surface spider cracks
or even a structural crack
with leakage. In this situation the water will start leaking to under the pool creating a series danger of squashing the pool shell
from inside out.
Pool structure stabilization
has been complete the pool structure must be secured by the proper combination of the concrete and rebar. Each manufacturer suggest the proper bond beam
for their pools. Pool installer
must follow suggestions and install correct pool bond beam
to secure the pool in ground.
- Fiberglass pool installation endure the highest upfront expense due to the high cost of fiberglass shell
- Different manufacturers use different shell manufacturing ingredients to reinforce their pools
- All gel coats created differently. The gel coat application methods might very as well.
- The fiberglass installation process is the quickest among all pool types.
- Most manufacturers of fiberglass pools offer lifetime warranties for their product
