GROUND COVER FOR CONTAINMENT BARRIERS

摘要

A ground cover for use as a containment barrier including a geomembrane sheet and a geotextile sheet bonded together by an adhesive layer positioned therebetween. The adhesive layer does not fully cure, remains tacky and has an adhesive strength sufficient to maintain a bond between the geomembrane sheet and the geotextile sheet under normal foot traffic and a release point allowing separation of the geomembrane sheet and the geotextile sheet under shear forces generated by heavier traffic.

1. A ground cover for use as a containment barrier comprising:
a geomembrane sheet having a first surface and a second surface; a geotextile sheet having a surface overlying the first surface of the geomembrane sheet; and an adhesive layer positioned between the first surface of the geomembrane sheet and the surface of the geotextile sheet, wherein the adhesive layer does not fully cure and remains tacky, the adhesive layer having an adhesive strength sufficient to maintain a bond between the geomembrane sheet and the geotextile sheet under foot traffic and having a release point allowing separation of the geomembrane sheet and the geotextile sheet under shear forces generated by vehicular traffic.
