One-Step Trowel-On Membrane is a self-gauging trowel-on membrane that acts as both moisture/air barrier and adhesive. One-Step Trowel-On Membrane produces a level surface of approximately 1.5 mm thickness of membrane and adhesive and allows simultaneous installation of drainage insulation. This feature makes waterproofing applications fast and easy, saving labor costs of 25% or more in efficient application of drainage insulation over vapor/air barrier membrane.
