Elevation® DM1 Drainage Mat

Elevation® DM1 drainage mat is a low profile drainage matting designed to create a sub-concrete drainage plane for quick and efficient removal of water from the balcony. At just 1/8” (3.5mm) total thickness, DM1 does not require modifications to the framing or T-bar dimension.


Elevation® DM1 drainage mat is a cylindrical studded membrane made with UV Stabilized polyolefin bonded to a polypropylene filter fabric. Once installed, DM1 drainage mat creates a continuous sheet of polyolefin plastic covering the entire surface of the balcony, providing an additional layer of water protection and a physical protective barrier to help protect/prevent damage to the waterproofing membrane beneath.
