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 Cav-Air-Ator allows it to be extremely light and flexible so that it can easily rest on top of the brick ties.

Masonry structures are built to last for up to 100 years. However, excess moisture can affect the durability and longevity of the structure. 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. Cav-Air-Ator protects against moisture issues in masonry applications by providing an unobstructed air space for drainage and ventilation.
