Trusted Waterproof Rubber Coating


The asphalt-based features of Perlastic™ are perfect solution for above and below-grade waterproofing on concrete foundation walls, footings, and tunnels. Plus, it works great on new construction or renovation of concrete slab projects. Global Polymer Solutions provides the complete Perlastic™ waterproofing solution with the seamless Roller Grade (RG), Trowel Grade (TG) and Spray Grade (SG) versions. The high elongation will bridge static and dynamic cracks up to ¼” (2.5mm) in concrete and masonry surfaces. Perlastic™ serves as an ideal waterproofing solution.


GPS-6000 (SealCrete™) is a fluid applied, single component which forms a smooth, tough, rubber‐like membrane that will elongate over 1500% without elastic damage. It resists penetration of water and will not become brittle when exposed to low temperatures. The durable film bonds tightly to most clean and firm surfaces. GPS‐6000 SealCrete™ is ideal for basement walls, poured concrete foundations and parged masonry concrete block walls.

Both of these products are easy-to-install with basic equipment and they are environmentally-safe.

Reliable Coatings for You

Perlastic™ is an excellent liquid rubber waterproof sealant because it possesses 800% elongation capabilities and eliminates the risk of bridging cracks. The elongation also allows coating to bridge cracks in the substrate and allows for substrate movement without the coating membrane cracking. Perlastic™ products are UV stable and topcoats are available in multiple colors, making life easy when you use these products as waterproof rubber coating. Perlastic™ membranes can easily be repaired, too—no need to worry about a total sandblasting or a membrane replacement.
