TrueDamp™ Dampproofing Membrane and Cavity Wall Vapor
Barrier is a carefully formulated, polymer-modified, waterborne,
asphaltic emulsion designed to provide resistance to moisture
infiltration when used for below-grade masonry surfaces and
as a vapor barrier membrane in cavity walls over concrete and
masonry surfaces. Its elastomeric and flexible film imparts a
tough, monolithic dampproofing membrane that, unlike most
other dampproofing, helps bridge nonstructural cracks and resists
moisture infiltration. It’s thixatropic consistency allows for easier
spray application to achieve film build without running and sagging
common to most dampproofing membranes.
By its ability to be spray applied, it eliminates the applicator’s
concern for seams, wrinkles, or voids in the applied membrane.
TrueDamp™ may also be used with insulation or drainage board
products to add additional protection and resistance to moisture.
TrueDamp™ meets or exceeds all requirements when tested for
ASTM D-1227-5 Type III, Class I Dampproofing material (Report
DX07FA June 2004).
Product advantages:
• Meets/exceeds ASTM D-1227-95
• Water-based
• Environmentally friendly
• Easy-to-apply
• Can be applied to damp surfaces and in cold climates
• Residential and Commercial applications below grade and in cavity walls
