CAVCLEAR® MASONRY MAT
CavClear® Masonry Mat provides full-height drainage protection behind brick veneer, ensuring a continuous drainage plane throughout the entire cavity. By eliminating mortar bridges, droppings, and obstructions at any point in the wall, it keeps the air space open, protects the weeps, and allows the masonry system to perform as intended. This results in improved thermal efficiency, reduced callbacks, and longer-lasting wall systems with fewer moisture-related failures.
BENEFITS
-
Clear air space – prevents mortar bridges and droppings throughout the entire cavity.
-
Continuous drainage path – eliminates weep obstructions and ensures reliable, uninterrupted moisture drainage.
-
Prevents moisture failures – reduces the risk of mold, staining, and moisture intrusion by keeping the drainage plane functional.
-
Minimizes thermal transfer – avoids mortar contact between wythes, improving overall thermal performance.
-
Saves money – lowers long-term maintenance costs and supports high-performing, energy-efficient masonry walls.
-
Flexible use – effective even in projects requiring a reduced cavity width.
APPLICATION AND INSTALLATION
CavClear Masonry Mat is specified and installed full-height behind brick in masonry veneer and cavity wall systems, both insulated and non-insulated.
