The purpose of the insulation of the pool is to prevent corrosion of the walls surrounding the pool and the iron reinforcement in the walls, to prevent the water that will leak from the capillary cracks that may be formed by the chemicals used in the pool water, and also to prevent the water that may come from the external walls of the pool in contact with the soil from polluting the water in the pool. applications are called pool isolation.
In pools, waterproofing is generally done with elastic, cement-free waterproofing materials.
