Description
The introduction of gas control barriers in cavities dictates one installs means by which all arrested gas and water can be routed out of the structure.

Cavibricks may be installed in the external skin under barriers to discharge gas in the cavity trapped below barrier level.
Caviweeps may be installed within perp joints to discharge penetrating water arrested on the upper surface of the barrier. (drawing)
