Polyglass U.S.A. Announces New Waterproofing Membrane for the Building Envelope

Polyglass U.S.A., Inc., a leading manufacturer of roofing and below-grade waterproofing systems, is proud to announce 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 (CMUs), stone, metal, plastic (PVC and ABS), wood (pressure-treated and fire-treated), rigid insulation, and insulating concrete forms (ICF).

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:

  • 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 (can be applied by roller, brush, trowel, or squeegee)
  • Free of solvents, tar, and asphalt

Polyglass is available to answer any questions about our new line of below-grade waterproofing solutions, including our adhesive primers, drainage mats, and post- and pre-applied waterproofing membranes.
