The invention relates to a method for making cellars and basements located in moist ground perfectly waterproof. It consists of a waterproof PVC pocket 1 covering the existing walls and rafts 2 which are exposed to the water pressures 3 due to the high level of the ground water table or various infiltrations. This pocket 1 is held in place by a reinforced concrete box structure 4 intended to resist the pressures. <IMAGE>
