Fluid Applied
RamProof GC (Green Concrete) is comprised of an industry changing asphaltic-rubber formulation that combines the elastic properties of modified rubber with the weatherproofing and waterproofing characteristics of emulsified asphalt. The resulting asphaltic-rubber membrane provides a complete, high-performance waterproofing membrane that is VOC-free, environmentally friendly, rapidly installed, and delivers a complete solution for the entire scope of waterproofing. RamProof GC forms to a single set, fully adhered, monolithic, and seamless membrane that results in a high-performance membrane that resists hydrostatic pressure, bridges cracks and will move with created expansion and contraction of surfaces.
HyppoCoat BC is a non-gassing, solvent-free, single component, liquid applied, water-catalyzed, polyurethane, elastomeric waterproofing basecoat. This unique product allows the base membrane to be applied in one application up to 3" (7.6 cm) deep down to a feather edge and cures simultaneously throughout the coating in approximately 4 hours at 75ºF (24ºC) and 50% relative humidity. The basecoat may be used for very rough or highly textured surfaces and where sloping or pond filling is desired. Please use the correct product grade that complies with VOC regulations as per federal, state, county, and city regulations/codes that adhere to the location of product installation.

Due to its fast gel time, HyppoCoat 100 is suitable for applications in temperatures as low as 20°F. HyppoCoat 100 is also relatively insensitive to moisture and temperature, allowing for applications in various temperatures and humidity. HyppoCoat 100 may be used as a stand-alone application for flooring, pedestrian and vehicular parking deck applications.
HyppoCoat GC (Green Concrete) is a user-friendly, high solids, single component, liquid applied membrane for cured or green concrete. The system uses two coats of a modified urethane coating and protection board to create an elastomeric system designed to expand and contract with normal structural movements. HyppoCoat GC is easy to use and can be applied immediately after green concrete forms have been removed, providing a quick return-to-service window during application. It also acts as an aggressive barrier against harsh chemicals, abrasive wear, and heavy impact.
