Drainage Mat for Brick, Stone Masonry Walls
Keene Building Products
A masonry wall needs an air space free of mortar and other debris to properly drain and ventilate. If moisture builds up and the wall is unable to dry, problems such as cracking, deterioration and efflorescence may occur. The CAV-AIR-ATOR protects against moisture issues in masonry applications by providing an unobstructed air space for drainage and ventilation. The full wall drainage and ventilation mat for full brick or stone masonry walls prevents mortar from entering the cavity, clinging to wall ties or blocking weep holes.
