Lock Moisture Out for Good with Reinforced Vapor Barriers
ECP’s new professional-grade 12 mil and 20 mil reinforced vapor barriers are engineered for long-term crawlspace encapsulation and moisture protection.

ECP’s Reinforced Vapor Barriers are designed to provide exceptional durability, puncture resistance, and moisture protection for crawlspaces and basements. Manufactured from 100% virgin polyethylene with high-density woven reinforcement, these vapor barriers help defend against ground moisture, soil gases, and mold while creating a cleaner, healthier crawlspace environment.
Get Reinforced Protection Against Ground Moisture
Ground moisture, humidity, and soil gases can create unhealthy conditions inside crawlspaces and basements. Left untreated, these conditions contribute to mold growth, wood deterioration, unpleasant odors, and reduced indoor air quality. Many vapor barriers tear during installation or fail to provide the long-term durability contractors need in demanding crawlspace environments.
ECP Reinforced Vapor Barriers combine multiple layers of virgin polyethylene with high-strength woven reinforcement to deliver exceptional puncture resistance, moisture protection, and long-term performance. Whether installing the versatile 12 mil barrier or the heavy-duty 20 mil version, contractors receive a durable encapsulation material engineered for professional crawlspace systems. The 20 mil vapor barrier also features an antimicrobial additive that helps resist mold growth while providing maximum tear and puncture resistance for the toughest crawlspace applications.
