The various exterior waterproofing(impermeabilizacion) barriers have varying levels of effectiveness in protecting the outside wall areas. But wall anti-leaking barriers do not affect water penetration due to water accumulation at the footer or floor level. The ideal solution to this problem lies in directing the accumulation of water away from the foundation or into drainage or pumping systems.

To control leakage in the basement, you may install a drainage system on the inner side of the foundation. The floor is broken up along the perimeter of the basement wall and drain tile is placed in a trench that carries the water to a discharge point impermeabilizacion , or sump pump, which takes the water away from the house.

With hollow block walls, holes may be drilled at the bottom to allow the water to pass into the drain pipe and relieve the water pressure. The trench may then be filled with gravel and the floor replaced or recemented.
If installed correctly this system will remove basement leakage water. Channels may also be installed on the basement floor to take the water away through a sump pump.

Apply Waterproofing(impermeabilizacion) Compounds To Interior Walls. Only in cases where mild and occasional capillary seepage occurs are applications of waterproofing(impermeabilizacion) paint or other interior compounds likely to provide any lasting degree of improvement in achieving a dry basement.

Capillary waterproofing(impermeabilizacion) materials can be applied to either exterior or interior wall and floor surfaces. If properly applied, they will penetrate several inches into concrete and close off capillaries or minor cracks by forming crystals in the presence of water. Do-it-yourselfers should carefully read the label to determine the waterproofing product’s limitations and terms of any guarantee promised. Waterproofing(impermeabilizacion) paint is most effective if applied directly over cement; not existing painted walls.
