Carlisle Coatings & Waterproofing Inc. (Wylie, Texas) introduced CCW-500, a hot-applied waterproofing membrane, a formulation that employs a post-industrial renewable resource. The membrane offers superior flexibility and crack-bridging ability, the company says.

The company also introduced MiraSEAL, a 100%-solids, cold fluid-applied, modified polymer that is reported to cure to form a flexible, monolithic waterproofing membrane suitable for vertical and horizontal concrete substrates. The single-component, moisture-reacted product contains no solvent or coal tar, and provides a high degree of adhesion to above- and below-grade concrete surfaces, even when moisture is present in the concrete, the company says.

The CCW-500 membrane is a single-component, 100% solids, rubberized asphalt compound that, when set after application, is reported to form a durable but flexible monolithic waterproofing membrane.

“Our goal was to improve performance and try to reduce our dependency on petroleum-based materials,” said Jason Covington, general manager of Carlisle Coatings & Waterproofing. “This was achieved by reducing the amount of asphalt used in the manufacturing process and incorporating the unique characteristics of a post-industrial, renewable resource.” The product is reported to contain 30% recycled content, classified as “pre-consumer.”

The material produces a rubber-like sheet upon curing, resulting in improved flexibility and performance, the company says. The product can be adhered to various vertical or horizontal surfaces, providing a high degree of waterproofing protection, the company says. It is reported to require less heat for application, stay workable for an extended period to allow for a wider installation time frame, and resist flow once the material has set.

The MiraSEAL waterproofing product is reported to provide complete waterproofing coverage without losing thickness during the curing process. With a water-vapor transmission rate of .06 perms and an elongation of 350%, the product offers strong waterproofing performance and flexibility, the company says. Recommended applications include structural slab and wearing courses on parking garages, plaza decks, balconies, roof decks, terraces, mechanical equipment rooms, wet rooms, malls, kitchens, and shower stalls. The company says the product is well suited for for waterproofing of foundation walls, tunnels, planters, and other areas where tough, seamless, elastomeric waterproofing is required.
