Damage occurs when the environment is moist, exposing joists, sill plate, support beams, subfloor, piers, block foundation walls, etcetera, to undesirable temperatures and water vapor levels.

 

However, crawl spaces can remain moist and damp without appearing muddy or wet due to a number of factors. The enclosed environment of the subsurface soil base, open-earth evaporation, elevation, topography, and exterior perimeter drainage, all contribute to the crawl space becoming very susceptible to mold, mildew, fungus, insect infestations, wildlife shelter, and other micro organisms.
 

Vapor barriers are useful at minimizing moisture and vapor that drifts up from the open-earth environment of a crawl space. Their purpose is to prevent the transfer and penetration of water vapor from one area to another. Vapor barriers excel at preventing mold, mildew, and other microorganisms from establishing a foothold.

They should not be used unless blatant indications of standing water and seepage from groundwater concerns have been ruled out or resolved. Vapor barriers usually serve best as an accompaniment to a drainage system.

 

Our systems do not allow any water getting past the dimpled membrane to fall freely to the drain tile through the air gap section, keeping water away from your foundation and preventing hydrostatic water pressure against your walls.

This same air gap allows the foundation to "breathe" and makes your whole home healthier.
