  • Geotextile/polyurethane/composite liners based on one-component heterogeneous liquid polyurethane compositions
    Publication number: 20050058838
    Abstract: The present invention relates to geotextile/polyurethane/polyurea and/or geotextile/polyurea composites prepared by soaking geotextiles with one-component heterogeneous liquid polyurethane compositions and subsequently curing by heat or solvent addition to form a geotextile/polyurethane composite. The inventive composites may find use as liners for canals and ditches for irrigation and wastewater, roof membranes, secondary containment, etc.
