When it comes to foundation wall seepage and water leaks, the most effective solution is an exterior waterproofing membrane application. This solution is especially effective with old porous concrete walls, old brick foundations, concrete blocks, and stone foundations. Many of the older homes in the Chicago area were built using these methods.
There are several types of waterproofing membrane systems. The best one for a home depends on the type and condition of the foundation wall, which will guarantee maximum efficiency and protection.
Once the membrane has been applied, it is covered with a heavy-duty drainage board. The board protects the membrane from damage and channels the water to an exterior drainage system that lies next to the footing of the building.
