Land Science®, a division of REGENESIS®, was recently awarded a U.S. patent for the use of a reinforced geomembrane composed of an encapsulated, metalized layer and installed with Nitra-Core™, a spray-applied nitrile-modified asphalt. This innovation provides 100 times more chemical resistance than other solutions and is integral to the enhanced protection built into Land Science’s MonoShield® and TerraShield® contaminant vapor barrier systems.
As part of the U.S. patent process, Land Science scientists presented lab testing data that compared the design of the new vapor intrusion (VI) barrier technology to commonly used high-density polyethylene (HDPE) systems.
Land Science’s design offers superior protection because it incorporates metalized film, a material proven to be highly effective at preventing the diffusion of contaminant gases. The advanced composite membrane prevents corrosion of the encapsulated metalized film and provides multiple layers of protection—including a reinforced grid geomembrane and geotextile. This reinforcement ensures greater tensile strength and enhances durability.
