Negative Waterproofing – New Construction : This method of waterproofing could be used for some flat areas inside the building, e.g. parking lots, corridors or tunnels when the high level of water cause a damp and wet surface. This method is used only after the concrete is completely dried and cured and before going through the finishing phase of flooring.
In this method, the cementitious capillary crystalline waterproofing materials is applied to the surface in a thin layer in order to prevent the water penetration to the internal area and make the wet or damp surfaces, completely dry!
