French Drain

A French Drain, also know as an Interior PRS (Pressure Relief System) is an important waterproofing solution which involves installing a perimeter drain on the interior of the basement. This consists of an underground piping system surrounded by crushed stone, which is then concreted over. All the underground piping is then commuted into an interior sump basin where the water is then pumped into a sewer line or to the exterior of the building. These systems can be either full perimeter or partial depending on your needs.
