Mark the area with the rough shape of the preformed pool with string and wooden pegs or garden hose.
TIP
Do not turn the pool over and mark the cutout area. If this is done, a mirror image is made. The pool will not fit if it is not a symetrical geometrical shape.
2
Dig the hole to roughly follow the contour of the pre-formed pool. The hole should be slightly larger than the pool itself. When the hole is dug, ensure that the pool rests level in the hole. If it is uneven the surface will appear lopsided and the effect will not be as beautiful as it could.
Next spread a layer of damp sand in the hole, 1 inch (2.54 cm) deep. Lay the pool into the hole and ensure that it fits properly. Backfill the hole with sand to ensure the pool is stable and doesn't move.
TIP
Use sand or excavated earth without rocks or roots to backfill the pool so it will be stable in the hole. Use a blunt stick or other implement to tamp the sand/soil into the hole enough to ensure there will be little, if any, settling. Work around the pool as you fill the hole to ensure the lip stays level. The sand cushions the pool from any rocks and roots left in the surrounding area.
3
Slowly fill the pool with water. Again ensure the pool settles into the sand/soil foundation levelly and without movement.
TIP
Why not use the excavated soil from the pond hole, mixed with top soil, to create a rockery or the rise for a waterfall feature.
4
When the pond is full, use rocks, paving stones or turf to hide the pool edge from sight.
TIP
If laying slabs or stones around the edge of the pool, they should protrude slightly to hide the pool edge from view.
