PREPARING THE LAND
The recommendations about the construction for completely or partially in-ground pools are effective in the context of an installation in land which is not humid.
You should conveniently adapt the basic instructions to avoid the restrictions related to the type of land (clay for example) or to the excessive presence of water
in the ground, (sources, run-off rainwater...). In order to avoid any excess humidity in your land, you should install a draining system under the pool, and around
it by building a decompression well. In all cases, an adapted draining system is necessary to avoid water stagnation with the possible consequences of ground
contamination including the deterioration of the structure (rooting of the wood, deformation of the structure...) To guarantee quality planning, you can consider any
information from a specialist as very important.
UNACCEPTABLE LOCATION: Sloping, uneven ground. Sandy, rocky or soggy ground.
LEVELLING
When levelling the ground, always remove material from the top of the slope rather than filling in the bottom: this will ensure greater ground stability and firmness.
Always remove all grass, roots, stones, etc. Levelling is extremely important: devoting the necessary time and effort to ensuring that your pool sits properly on the
ground will avoid problems later.
How to level: thanks to a large mason rule (aluminium or wood) and a level, level out the ground forming rectangles (or squares), locating this rule in the selected
and cleaned area. When all the areas are on level and when the excess of ground is removed, you may fill in the small areas which are left to level out (with clean
ground or sand) but always compacting and levelling again afterwards. It is very important the installation area is well-compressed and firm in order the ground
do not subside when the pool will be full of water. Please ask a professional: builder, gardener...
Important: you should make a concrete slab.
The bag should be perfectly flat and smooth, to avoid any imperfection.
PARTIAL OR COMPLETELY IN-GROUND INSTALLATION
According to the nature of the land, you should install a peripheral drainage and connect it to a decompression well. The well will be excavated before the
construction of the pool to avoid that the excavations fill with water during the works. It should be near the pool, a few centimetres lower than the deepest point
of the same and reach up to the surface. The decompression well is located at the most humid point. It acts as an overflow in the case of water infiltrations or clay
soil, starting from the fact that water rises quicker through a tube than through the soil.
