Landfill
(for fully or partially in-ground pools)
In fully or partially in-ground pools, a gravel landfill is necessary to favour perfect draining.
The landfill of a pool can seem a mere formality, because a first sight there are no special technical difficulties. Nevertheless, it is
a more delicate operation than what it seems, for which certain precautions are necessary.
An incorrect landfill can give way to later deterioration of the pool and its surroundings. It is necessary to consider the type of
material being used and to perform all the necessary verifications.
Before performing the landfill, you should:
• Check that all the hydraulic and electrical equipment is well connected.
• Check the water tightness of the connections of the channelling, especially regarding those sealed parts.
• Protect, if applicable, the peripheral draining tube covering it with geotextile. It is important to fill the pool in parallel to the landfill
in order to balance the pressures and that way avoid deformations of the structure during the operation. We recommend following
the landfill technique by thirds (1/3 of water and 1/3 of landfill)
During the landfill, we recommend processing by successive layers around the entire perimeter of the pool to not run the risk of
damaging the structure.

• Position the alveolar HDPE protection (not included) around the pool.. The alveolar protection, should, likewise continue over the slab
and all round the outside of the same.
• To avoid draining obstruction, you should place felt on the natural soil (not included) to retain the soil.
• Install the peripheral draining over the protection and connect it to the decompression well (if applicable). Otherwise, leave the draining
extended over the land.
• Now, make the landfill against the walls with compacted gravel (10/30 calibre) that will facilitate drainage.
This landfill should be done at the same time that you fill the pool.
Land-filling with vegetable soil is prohibited.
