In the drainage areas to be applied around the foundation, the membrane is effective only in reducing the pressure of the groundwater. Due to this feature, the most used area of the product is the building foundations. Again, concrete material does not have a full insulation feature regarding water. The membrane ensures that the concrete is fully insulated against water. This insulation carries vital function. Because, water leaking into concrete structures damages iron or steel hardware over time. As a result of the corrosion of the steel, the building weakens and a big risk problem arises. At this point, the membrane grows to rescue. It ensures the long life of the building.
