Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.
This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.
A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.
This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
