Foundation Waterproofing

All masonry foundations--whether they're block, brick or stone--are typically constructed using mortar to hold the individual masonry units in place. Over time, mortar can deteriorate, allowing water to seep through the open joints and into your building. We provide foundation waterproofing solutions to help with seepage control for your basement.

We offer both exterior and interior methods of repair. The exterior foundation waterproofing method involves excavating the foundation wall(s) to expose the leaking areas. Depending on the condition of the wall, some minor surface restoration may be required. A waterproof membrane is applied to the foundation wall(s). Once the membrane cures, the trench is backfilled with the excavated material. If the wall(s) is excavated to its base, a drain tile can also be added to collect the water and direct it to an appropriate drainage location.

The interior seepage control method, commonly referred to as an Interior Drain Tile System, can also be used to address the problem. As a part of the foundation waterproofing system, our exclusive Hollow Cove Molding is installed at the base of the wall(s). Any water penetrating the wall will continuously drain into the molding and then into the system. U.S. Waterproofing provides foundation waterproofing and seepage control in the Chicago area.
