<p>A procedure for making swimming pools and artificial lakes in general includes the following steps: excavation of a tank; preparation of a subgrade by spreading the bottom of the excavation with a layer of sand; then spreading one or more sheets of nonwoven fabric on the inside surface of the excavation, over the layer of the subgrade; placement of a waterproofing layer over the sheet(s) of nonwoven fabric; installation of the equipment needed for proper functioning of the tank, swimming pool, etc; and application of a coating on the inside walls and/or on the bottom and/or around the edge of the tank, with holes or interstitial spaces such to enable water contained inside the tank to come into contact with the sheets, wherein the thrust of the water contained in the tank thus comes to bear on the sheets.</p> |
