Drainage Mat for Brick and Natural Stone Walls - Cav-Air-Ator®

The Cav-Air-Ator® is a full wall drainage and ventilation mat for full brick or stone masonry walls. It prevents mortar from entering the cavity, clinging to wall ties, or blocking weep holes. The innovative design of the Cav-Air-Ator allows it to be extremely light and flexible so it can easily rest on top of the brick ties.
