Waterproofing Membrane

         Polyglass® U.S.A., Inc., a manufacturer of roofing and below-grade waterproofing systems, has announced the release of a new structural waterproofing membrane product for the building envelope, Mapeseal™ GC.

         Mapeseal GC is a single-component, fast-curing, cold-fluid-applied, monolithic waterproofing membrane ideal for vertical and horizontal surfaces and damp and green concrete applications.  A seamless, 100%-solids, moisture-curing waterproofing membrane, Mapeseal GC is compatible with common construction materials such as concrete, concrete masonry units, stone, metal, plastic, pressure-treated and fire-treated wood, rigid insulation, and insulating concrete forms.

         Mapeseal GC will not shrink and is VOC-compliant in virtually all municipalities.  Its low odor makes it well-suited for use in and around occupied spaces.  For critical applications, the system can be reinforced with Mapeseal Fabric. 

         Features and benefits include: single-grade membrane for vertical and horizontal applications; can be applied in a variety of thicknesses or with reinforcement, making it customizable to any job; does not require a primer; applies easily with no mixing or special equipment required, and it can be applied by roller, brush, trowel, or squeegee; and is free of solvents, tar, and asphalt.
