Disclaimers
This article is a summary of the process of installation of a pool in a conventional polyester shell. A polyester shell should always be filled with water (at ¾ of the skimmer). Consult your installer and apply the usual precautions for any discharge, may it be partial or full. It is imperative to check whether there is any water in the basin, especially in the winter, in heavy rain conditions or in the presence of a high water table in the basement.
No chemicals should be poured directly into the basin as skimmer baskets and disinfectants are provided for the same purpose. Do not use products that are not specifically recommended by your installer, including copper sulphate or other products loaded with metal ions. They may cause incompatibilities with the coating of the polyester shell. Use only plumbing supplies like Pex or Ferguson.
Never use a grinder or projection equipment for metal parts near the pool.

The installation of a pool
Even before the opening of the site, t is essential to define the boundaries of the site of and ensure that no underground water or electricity passes through that location.
Implantation in natural sloping terrain
A lot of conditions need to be taken into consideration when it comes to ensuring the stability of the pool when the ground surface is not horizontal.
There are two possibilities:
Case 1: Creating a platform for the disbursement of land
The upper slope stability must be such that the wall undergoes no thrust. The lower slope must be strong enough to ensure the stability of the hull.
Case 2: Creating a retaining wall
The characteristics of the wall are determined by the slope and the size of the pool. In any event, it is advisable to bring a skilled artisan to design this type of work and to manufacture it.
The quality of the soil
After determining the location of the pool, you have to learn about the soil and its stability. The polyester shell must be installed on stable, coherent, homogeneous and water-free ground. It is strongly advised to conduct a survey (trench, auger, drill...) at the site in case of uncertainty regarding the nature or the homogeneity of the soil. The stability and consistency of the soil determine the filling. Particular attention should be paid to the quality of the subsoil and the water drainage on and around the pool, beaches and stairs.
The definition of the zero point
A tracking sheet facilitates the tracking down process significantly, but you have to draw the pool in the absence of a cover, making sure it is square to the ground.
Tools: stakes, cords, tracers and decameters
Measure four meters along the AD line starting from corner A. Point X is thus obtained. Take corner A and measure three meters in width. Point Y is thus obtained. The distance between points X and Y (hypotenuse of the triangle) must be equal to 5 meters and if there are more than 5 meters, the opposite angle is greater than 90 degrees (open), while if there are less than 5 meters, the opposite angle is below 90 degrees (close), so you must adjust the angle to get a perfect squaring.
Check the ratings for your pool excavation after getting the correct 90 angle. Measure the two diagonals AC and BD to check if the distance is correct. You must obtain the same length between AC and BD. Check your blind if you don’t. Make sure the path corresponds to the chosen location.
The zero point
The level point called 0 (zero) point serves as a reference point for the finished work. It defines the level of your pool in relation to the arrangements or the slope of your land. It can be determined using a telescopic surveyor or water level. The 0 point is referential throughout the site. Mark the 0 point out of the access and traffic areas.
Earthwork
The aim of earthwork is to achieve an excavation to receive the hull. Particular care must be taken in this operation. The search must be clean and purged of any element of resistance or sag. Observe the Coast moving data (between 20 cm and 30 cm from the inner side of the pool).
Do not compensate with loose soil if the excavation is oversized (too deep), but use reconstituted stabilized soil. Add a geotextile on the bottom. People usually resume the desired level with ballast (80 mm).
Major excavation is required to perform the work if the ground is not stable. Therefore, the implementation of the embankment becomes essential. Thus, it is necessary to create a reconstituted soil stabilized with riprap, which reduces the width of the excavation.
