GeoFlex

Product Description
GeoFlex geomebranes are your new solution for highly flexible lining materials. The unsupported styles of GeoFlex are some of the most flexible materials available for use as a geomembrane, making detail work such as attaching to structures, building tanks, or creating corners an easy task. In addition to flexibility GeoFlex has outstanding resistance to low temperatures and is highly UV resistant. GeoFlex geomembranes are your clear choice for water and water based effluent storage when the liner will be left exposed.  Layfield's GeoFlex is manufactured at our facility in Vancouver BC. Layfield's GeoFlex is a unique blend of virgin polymers and additives that have been optimized to deliver flexibility with UV and chlorine resistance. Layfield's registered quality management system ensures that your GeoFlex geomembrane will consistently meet our specified properties, and perform to the highest industry standards.
