RFISS-182 Distro A - Geomembrane Covers.pdf

This document is a technical installation drawing for a geotextile and high-density polyethylene (HDPE) liner system. The sheet provides detailed cross-sectional and sectional views of a containment or barrier installation featuring a 60-mil HDPE liner with non-woven geotextile backing, designed to be anchored into an existing concrete structure. Key installation components include an anchor trench system with welded liner seams, 1-foot cover soil layer, 2-foot typical spacing intervals, loader wheel-compacted backfill, neoprene gaskets, caulking, flat bars, and wedge-type bolts with nuts and washers for securing the system to existing concrete.

The drawing references GEOCOMPOSITE 200-2-6 manufacturer's requirements and is marked "Approved for Public Release" for distribution. The technical specifications indicate this is a reference document requiring adherence to the manufacturer's installation guidelines. The drawing was last saved by Joshua Combel on August 27, 2026, and is formatted on an 11" x 17" sheet with no specific scale indicated. This type of technical drawing would typically be included as a specification or design attachment within a federal contract solicitation for environmental remediation, wastewater containment, or similar infrastructure projects requiring liner installation.
