Selecting the Right Crawl Space Moisture Control System for Your Wet Crawl Space
Here are the primary three solutions for moisture control in a wet crawl space:
- 6-mil Poly Plastic Liner
- “Crete” Spray Concrete and Vermiculite
- AquaStop Crawl Space Encapsulation System
Not all vapor barriers are created equal. A 6-mil poly solution is the cheapest way to go, performs the worst and is prone to tears, punctures, begins to disintegrate from UV radiation in a short period of time, and easily pulls from the walls when even installed on them.
The “Cretes” are a light concrete that is sprayed into a crawl space that has some insulating qualities depending on thickness, but does not address moisture as this fluffy cement and vermiculite concrete is even more porous than typical concrete and water vapor readily passes through. Cretes typically come with a 5-year warranty as they don’t stay on the walls well and crunch and crack when crawled on due to their softness. Crete costs about twice as much as a liner system.
The Crawl Space Solution…
The AquaStop crawl space encapsulation system is a heavy 20-mil-thick material, similar to a pool liner, but highly impervious to rips or tears. It is bright white on top and really brightens a crawl space, allowing you to see just how free of mold, insects, and dirt your crawl space now is. The vapor barrier has the Ultra-Fresh anti-microbial agent built in to help kill bacteria when it comes in contact with it. The AquaStop liner is tough enough to crawl on and enables you to use your crawl space for storage. Service people can crawl on it without the worry of puncturing or tearing the liner.
The AquaStop vapor barrier, part of the AquaStop crawl space encapsulation system, is the best solution as it addresses the moisture issue and is very tough and durable. AquaStop vapor barrier isolates a home from the earth, reducing the relative humidity level in the air. The liner completely stops moisture penetration, lowering relative humidity levels and reducing or even eliminating mold growth, rot, and critters from a crawl space, making the entire house healthier.
Other products that make up the AquaStop system include the WallCap concrete block caps that prevent damp air from rising into a crawl space through hollow concrete blocks, the AquaStop crawl space sump pump system, foam sealant to stop air penetration, Vent Covers to seal out unconditioned outside air, tight-sealing crawl space doors, the crawl space conditioning fan, and the AquaStop crawl space dehumidifier – all parts of the total solution.
