GFG20X 31 mil (16 mil HDPE + 15 mil geotextile-backed) protection sheet is constructed to restrict chemical and moisture migration through HydroGel and Turbo-Seal polymer rubber gel (PRG) waterproofing systems, primarily for horizontal deck applications.
This sheet is made from proprietary polyolefin resins that have been independently tested against ASTM E 1745 requirements (Standard Test Methods for Water Vapor Barriers used in contact with earth under concrete slabs) showing superior permeance and superior physical properties.
