Crawl space is traditionally the most misunderstood part of your home. It encompasses many crucial building components of the foundation. A compromised crawl space endangers the structural integrity of the foundation system.

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.

 

Groundwater levels differ according to the amount of rain and snow received. These fluctuating levels are the
crux of crawl space moisture problems. If the groundwater level remains near the crawl space grade, water levels can range from complete flooding to smaller areas of standing water.

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:

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.


 


You can't go wrong with our services as long as rain continues to fall in the lower mainland!

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.

Quality builders and concerned home owners use - Drain Master Plumbers on all their projects to ensure their
home have dry basements and crawl spaces!
