So let’s start. Firstly, the plot for the construction of pools must be carefully studied, analyzed. If the soil turned out to be clay, then the pit for the bowl will have to be made deeper. The resulting space (about 1 meter deep into) must be covered with sand and gravel, properly tamped. Thanks to this, the negative properties of clay soil will be eliminated, and in the appendage we get a good drainage system for our pool.
