- About MTI
Gravity CavityTM rainscreen drainage plane (drainage mat) is the economy alternative to our Sure CavityTM drainage plane (drainage mat) product. It works because it maintains a separation between the materials used for the veneer and the structural back-up wall to drain incidental moisture and dry out the building enclosure. Gravity Cavity drains and dries better than mesh-based drainage matrix products because its 1/8” deep channels enable moisture that enters the building envelope to travel quickly straight down and out the bottom of the wall, and it won’t compress behind siding.
