Stucco Drainage Systems

WaterWay Plus

A revolutionary Patent Pending Vertical Wall Rainscreen Drainage Mat consisting of a nominal 7/16 inch / 11mm thick extruded polymer matrix of tangled monofilaments. The monofilaments are heat laminated to an impenetrable, breathable, filter fabric on one side and a code compliant weather resistive barrier on the other side. This multiple layer product creates a one step weather resistive barrier and rainscreen drainage assembly in a single application. WaterWay Plus is designed for use with manufactured and natural stone, traditional and one coat stucco, EIFS, fiber-cement and wood based sidings, masonry, metal and other wall cladding materials. This rainscreen product provides an un-interrupted drainage path & ventilation for incidental moisture between exterior finish materials and wall sheathing.
