flooded crawlspace


Crawl space moisture problems have been a challenge for homeowners for nearly one hundred years. Waterproofing the basement and moisture proofing the crawl space utilize separate technologies to arrive at an acceptable problem resolution.

Moisture, mold, and fungus growth are issues that plague many homeowners in the Carolinas.  It’s very common for older homes to lack proper ventilation systems.  This poor air quality can lead to dangerous and costly damage to the structure of your building. In a quest for more energy efficient homes, builders are attempting to build homes tighter and because of that, crawl space ventilation issues become more challenging. Today’s state of art homes and HVAC systems require an engineered solution to fully control moisture in the crawl space without creating additional issues.

  Reduce water getting into the crawlspace


Water needs to be routed away from the foundation.
– gutters should be kept clean and in good working order

– downspouts need to drain away from the foundation.

– the ground should be pitched away from house as much as possible.

– there should not be any water standing in the crawlspace after a rainfall.

If there is, the crawlspace may need a sump pump or an interior drain system for waterproofing.

Often standing water inside the crawlspace can be solved by proper exterior maintenance and  planning outside of the home footprint to supplement waterproofing efforts.

 Cover the ground with a vapor barrier


Moisture in the crawl space must be contained.
– there are various opinions on how much coverage and what type of plastic should go into a  crawlspace to help waterproofing the crawl space.

– the vapor barrier plastic, usually 6-10 mil polyethylene, covers 100% of the crawlspace floor.

– the vapor barrier extends up the crawlspace walls, the height of which varies depending upon crawl space conditions. The vapor barrier may extend up to home’s sill plate but must be exposed at least 3″ for termite inspections.

– the vapor barrier must be sealed to the foundation to contain the moisture.
