Introducing CAV-AIR-ATOR™, the Lightweight, Full-Wall Drainage Mat for Brick
and Stone Masonry WallsMayfield Heights, Ohio—March 1, 2011 – 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. The CAV-AIR-ATOR™ protects against moisture
issues in masonry applications by providing an unobstructed air space for drainage and
ventilation.
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 that the wall ties that it rests on top of easily support it.
The CAV-AIR-ATOR™ is made up of an extruded polymer matrix of entangled monofilaments
that form block-shaped channels. In masonry walls, it leaves 96.5% of the cavity
unobstructed and free to breathe. A lightweight filtered fabric is laminated on one side of the
product to prevent mortar from entering the cavity while still allowing for enough finger room to
lay the brick. The extremely high airflow and lack of mortar intrusion allows for efficient liquid
moisture drainage and uniform airflow in all directions.
