Geo-Seal® 60 is designed to provide a cost-effective alternative for sites desiring a pre-emptive mitigation solution, but also wish to have a vapor intrusion barrier that is more robust and resistant to construction traffic than simple single sheet membranes. While simple single sheet membranes may provide robust chemical resistance, they often lack robust seals around penetrations and termination points. They are also more prone to punctures during the construction process. Geo-Seal® 60 makes the decision easy for those debating whether to employ a simple single sheet membrane or utilize a thicker, more robust barrier to protect human health at similar price points. The Geo-Seal® 60 system is comprised of three distinct layers: Geo-Seal® FILM 11, Geo-Seal® CORE and Geo-Seal® BOND.
Geo-Seal® FILM 11 is an HDPE Class A vapor barrier that alone will meet the basic water vapor barrier requirements for projects and the American Concrete Institute (ACI).
The Geo-Seal® CORE layer, applied at 30 mil to Geo-Seal® FILM 11, creates a seamless barrier that increases the overall composite system’s tensile and puncture strength.
The HDPE Geo-Seal® BOND protection layer ensures the previously applied layers will remain protected during concrete placement and mechanically bond the system to the foundation during the concrete curing process to maintain building protection in the event of soil settlement.
