Exterior Waterproofing Membranes

Sometimes it is impractical or undesirable to waterproof a basement from the interior. Common examples include seepage over the top of the foundation, porous concrete walls or instances where the basement is highly finished. Exterior waterproofing membranes address the problem from the “positive side” by excavating and applying a coating to the foundation wall. Depending on the situation, it also may involve adding a perforated drain pipe surrounded with washed stone at the base of the trench to get rid of the excess water.

Potential obstructions such as additions, garages and decks need to be taken into consideration. We can remove items such as concrete, asphalt and pavers. In most instances, digging is done by hand to minimize disruption to landscape.
