Often, crawl spaces also need to be waterproofed to ensure that they stay in good repair.

The purpose of a vapor barrier is to slow or prevent the evaporation of ground moisture into the crawlspace air. When coupled with a crawlspace waterproofing system, unwanted moisture and water can be removed from the crawlspace before it can cause problems.

The purpose of a vapour barrier is to restrict the passage of moisture-bearing air. By preventing air movement from the ground, it can also make your crawlspace into a semi-conditioned space, meaning that it is close to the temperature of the living spaces above. When this happens, the floors feel warmer in the winter and your energy bills shrink.
