    This basement was used to store important items to a business. They didn’t know that it would all be destroyed by a water leak costing them tons of money. We came in and installed drain matting to channel the water, SilverGlo wall which acts as a vapor barrier and insulator, a perimeter drains to collect the water and a sump pump to collect the water and discharge it out of the basement and a usable storage space.

Exterior Excavation

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.

Interior Subfloor Drain

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.

Interior Baseboard System

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.

Negative-side Sealant

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.
