The causes of a wet basement

Did you know you can have water issues in your basement without heavy rains or obvious standing water? It's easy enough to see water coming through a crack in your floor or basement wall, but what's the real cause of your basement water problem?

The Clay Bowl Effect

Excavated soil that's replaced around a completed foundation isn't as dense and tightly packed as undisturbed soil farther away. As a result, water collects in the soil immediately surrounding the house, putting pressure on foundation walls and causing cracks.

Hydrostatic Pressure

As soil around your foundation becomes soaked with moisture, it expands and puts pressure on your foundation. The water will then work its way through any opening available, including cracks and openings around pipes or windows.

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.
