Pool Installation

We do not install pools. We sell swimming pool kits. The below guide provides a level of
understanding of the key steps to install a pool. This guide is not detailed enough to
allow you to install a pool directly.

A guide for the installation of a
fibreglass pool shell


Select the position for the pool installation. Select a fixed datum point like a concrete patio or a ‘mark on the fence. This datum point will then become the reference point for all measurements. Mark out the shape of the pool and dig the hole 80mm wider than the shape of the pool shell.

The depth of the excavation should be the same as the depth of the pool shell plus an extra 150mm to allow for the sand bed for the base of the pool shell.

A water level can be used for the excavation and levelling the pool shell.
If the depths of the pool shell is l800mm to 1000mm then the depths of the excavation should be 1950mm at the deep end and 1150mm at the shallow end, all measurements are in relation to the datum point.


When the excavation has been completed, the sand can be placed and screeded to exact depths of the pool shell (1800mm to l000mm). Course river sand or crusher dust can be used for the bed of the pool. Fit the skimmer box to the pool shell and the pool return fittings, and the hydrostatic relief valve. The shell is then placed into the excavation with a crane using a spreader bar.

Check the top of the pool for correct levels before the crane is dismissed, in case the pool has to be removed. After the pool shell has been placed and the levels are correct, place a 90mm plastic pipe at the deep end of the pool next to the skimmer box. This pipe must end up below the base of the floor of the shell, this pipe is so access will be available to pump out any excess water that may be around the excavation.


The pool is now ready to start filling with water. When you are filling the pool with water you must do a dry 8 x 1 sand and cement mix around the outside of the pool. Do not wet or pack the backfill except for packing under the step area.

Bring the water level and the backfill up at the same level together to avoid external & internal pressure on the pool shell – in other words always keep the levels the same as you are filling the pool.

You can do about 200 mm high of backfill around the base before you start to fill the pool with water just to hold the shell in position while you fill & backfill.


The plumbing can now be connected. The pipe to use is class 9 pressure pipe, the pipe from the skimmer box to the pump is 50mm and the pool returns can be 50mm or 40mm pipe. Continue filling the pool with water until the water level is approx 40mm below the top of the skimmer box opening.

The backfilling can now be completed. The sand and cement backfill can be tampered if necessary to obtain the natural shape of the shell. The concrete bondbeam can now be constructed after 2 days from the completion of the backfilling.

The concrete bondbeam is a structual part of the pool construction, details as per specifications on plans.
