Land Science Technologies^™ a division of Regenesis, Inc., is proud to announce that the Geo-Seal^® Vapor Intrusion Barrier was recently granted a United States patent in July 2011. Geo-Seal is designed to prevent contaminant vapors such as VOCs and methane, which come from subsurface sources, from migrating into planned or existing buildings. More specifically, the technology is a composite vapor intrusion barrier comprised of a 60 mil spray-applied asphalt barrier encapsulated between two HDPE layers. This patented approach to vapor mitigation creates the ideal blend between chemical resistance and constructability to provide long-term protection against VOCs and methane gas.  Additionally, the Geo-Seal system can be customized to meet project specific needs such as:

1. Buildings constructed in below grade or in the water table
2. The retrofitting of existing structures
3. High-risk sites with extreme levels of contamination

Used on a wide variety of sites across the United States, Canada and Europe, Geo-Seal applications range from fast food restaurants built on former gas stations to residential developments built over legacy VOC plumes.  Geo-Seal is often combined with Vapor-Vent^™ for maximum, long-term vapor intrusion protection.  Vapor-Vent is a low-profile, trenchless venting technology that is installed in a permeable medium of either gravel or sand and can be designed to actively or passively alleviate the buildup of vapors beneath the structure.

Where warranted, Geo-Seal is an integral part of the site remediation process and can easily be installed in combination with any of the in situ remediation technologies offered by Regenesis.
