CRAWLSHIELD Crawl Space Encapsulation
Because the distance between a crawl space floor, dirt or concrete, and the ceiling (the flooring and joists of the first floor above) is much less than that of a full size basement, there is not as much cubic footage to allow evaporation. The best way to eliminate moisture problems and basement mold is to separate the crawl space from the flooring above by encapsulating the walls and floors of the crawl space with CrawlShield. CrawlShield is thick, tough liner (think of a swimming pool liner in white), that completely covers the crawl space walls and floors. Moisture is unable to penetrate the barrier, and therefore unable to reach the areas that can create problems. Vents in the crawl space are also covered and sealed to keep unwanted humid or cold air out of the crawl space.
Now that the moisture from the ground below and the vents above are cut off, the relative humidity in the crawl space is maintained at a level below that at which basement mold can grow below 50% with the CrawlShield SaniDe Air System. This system will dry and clean up to 2200 square feet of crawl space, it is fully automatic no buckets to empty, contains a two stage air purification system, and in energy star rated!
Crawl Spaces with Water Seepage
If actual water seepage is present in the crawl space, additional measures need to be taken before the CrawlShield system is installed. A WaterVac water evacuation basement drainage system would be installed first. This system is new wet basement technology specifically designed to drain water from crawl spaces in one of 3 ways—either a perimeter system (in the case where there is a concrete floor), a drainage matt (where there is a level dirt floor), or “finger” drains (in cases where there is an uneven dirt floor). The idea is to drain the water to an UltraVac water evacuation unit, where it is pumped out away from the crawl foundation automatically.
