The Henry 789 Fibered Asphalt Emulsion Damp Proofing is designed for damp proofing the exterior side of below grade foundations and walls. Above grade, Henry 789 provides a moisture barrier used for damp proofing the exterior walls in cavity wall construction. Made from selected asphalt, emulsified with bentonite clay, non-asbestos fibers and water contains no solvents.

Features:

• It can be used above-grade to provide a "breathable" moisture barrier, used for damp proofing the exterior walls in cavity wall construction
• Fibers aid sag resistance in vertical applications
