Exterior waterproofing is the best application of waterproofing for foundations, but also the most expensive. Exterior and foundation waterproofing is most ideal during renovation, repair or construction of a home or commercial building. Water is prevented from entering the building through membranes, drain pipes, grading, and redirecting of other water lines (such as roof leaders). When doing excavation work on your building, we handle permits, call for mark-outs, and cautiously monitor all areas we dig. As an added benefit, we also repair damaged sprinkler lines if not marked out.
Interior drain tile systems are used as a complete solution to control and prevent just about any type of seepage. They are designed to keep the water table far below the bottom of the basement floor, this controls the capillary action or wicking of water or water vapor on to the basement floor. The procedure involves opening the floor along the perimeter foundation wall(s) and installing a perforated drain pipe surrounded with washed gravel at the base of the wall, then cover the gravel with a filter paper and drain track as seen in the picture below, after we re-pour concrete floor and clean basement. The system then collects water from multiple sources and empties it into a sump pit.
