10 Mil Durability

Commercial-grade 10 mil thickness resists tears and punctures during installation and stands up to crawl space traffic—thicker than standard 6 mil poly.

Prevents Mold & Damage

Stops moisture from reaching floor joists, insulation, and HVAC systems—preventing mold growth, wood rot, and structural damage.

Encapsulation Essential

Foundation of proper crawl space encapsulation—works with sealed vents and dehumidification to create a controlled, dry environment.

Crawl Space Vapor Barrier - 10 Mil Polyethylene Moisture Barrier

Ground Moisture Protection

This heavy-duty 10 mil polyethylene vapor barrier is the foundation of effective crawl space encapsulation, creating a moisture-resistant seal between the ground and your home. Installing a quality vapor barrier prevents ground moisture from evaporating into your crawl space, protecting structural wood, eliminating musty odors, and stopping mold and mildew growth that threatens your home's air quality and integrity.

Professional Installation Tips

For best results: remove debris and level soil before installation, overlap seams by 6-12 inches and seal with vapor barrier tape, extend barrier up foundation walls 6-12 inches and secure with termination bar or adhesive, seal around piers and obstacles, and consider adding drainage matting underneath for enhanced moisture management.
