A high-performance polymeric waterproofing membrane and vapour barrier for interior wet room applications, including steam showers and steam rooms.


Product Overview

HYDRO BAN SHEET MEMBRANE and the preformed corners and collars provide a high-performance, low-perm waterproof matting system for use in interior applications including wet rooms, steam showers and steam rooms. 

The system is typically installed using a substrate appropriate LATICRETE® thin-set. Due to the material's polymeric construction, these preformed sheet membrane components can also be used as a vapour barrier and waterproofing membrane for steam room and steam shower applications. 

Available in rolls, tapes, corners and collars, HYDRO BAN SHEET MEMBRANE allows for a quick, easy waterproofing installation and will retain its integrity for the life of the installation.
