Gel-Flex GFG20X HDPE per Roll

Gel-Flex GFG20X HDPE

Class A Vapor Retarder Membrane Radon, Methane, Sulfate, and Soil Contaminant Barrier.

GFG Series protection sheets are membranes constructed to restrict chemical and moisture migration through Kingfield's Gel-Flex polymer rubber gel waterproofing systems. These materials are made from proprietary polyolefin resins and 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 physical properties. GFG membranes are available in several thicknesses: 11, 16, 21, 26, and 31 mil thickness in corresponding GFG designations: GFG11, GFG16, GFG21, GFG26, and GFG31.

Applications

• Protection of Gel-Flex Systems
• Groundsheet Protection for Novatak Systems
• Vapor Barrier Geomembrane

Key Features

• Exceeds ASTM E 1745 class A, B, & C standards
• Mitigate transmission of radon, methane, sulfates, and many other soil contaminants
• Ribbed texture reduces sheet & lap seam slippage

Kingfield͛s GFG Series are also offered as a composite membrane: GFG20X. For added strength, 16 mil GFG HDPE membrane is laminated to 15 mil polypropylene nonwoven geo-textiles to meet the toughest performance specifications. The geotextile provides cushion, increases grip, and ensures positive contact with the Kingfield Gel-Flex systems.

GFG Series protection sheets restricts the transmission of chemical laden ground water and water vapor from passing through Gel-Flex membranes and concrete slabs. Properly installed GFG Series protection sheets will protect floors and walls susceptible to moisture damage from vapor migration through the concrete slab and horizontal vapor transmission. Also, GFG Series vapor barriers significantly decrease interior moisture condensation, mold͕ and help provide a dryer, healthier environment to your building.
