Features of the CrawlSeal™ Liner:

  • Heavy 20-mil-thick liner – Similar to a swimming pool liner
  • Manufactured in 7 layers – Combination of high-density polyethylene for puncture resistance, low-density polyethylene for flexibility, and polyester cord for reinforcement for brute tear resistance
  • White finish brightens the crawl space and makes it easy to see that the crawl space is free of mold, insects, and dirt
  • Antimicrobial additive prevents mold from growing on the liner

How a Crawl Space Moisture Barrier Works

A vapor barrier does exactly what its name says: it provides a barrier against water vapor. When warm air comes in contact with a cool surface, condensation forms. When this happens inside the crawl space, the moisture can lead to mold growth, cause wood beams to rot, and attract pests.

A vapor barrier slows or prevents ground water seepage from evaporating into the crawl space air. For a crawl space to stay dry, it’s also important to make sure there’s proper drainage and keep gutters and downspouts clear of debris.

Our Crawl Space Vapor Barrier Installation Process

  • Wood and organic materials are removed.
  • Rocks are removed and uneven surfaces are leveled (depending on condition).
  • The CrawlSeal® liner is carefully fitted and installed on the crawl space floor and walls.
  • Drilled-in fasteners and spikes are installed to permanently hold the liner in place.
  • Edges, seams, and pipe penetrations are sealed.
