Geo-Seal® EV40s

Geo-Seal® EV40s is a significant improvement over existing single sheet membranes. Geo-Seal® EV40s consists of an EVOH membrane combined with a robust geotextile layer to provide a single sheet vapor intrusion barrier that is chemically-resistant and easy to install, while also providing improved protection during the installation process.

Geo-Seal® EV40s is ideal for lower risk sites where site concentrations are at or below state-specific screening levels or large, wide-open, flat sites where speedy installation times are required. It’s also a perfect complement to projects that seek to implement active sub-slab ventilation systems.
