About this material

A bonded sheet membrane that becomes the waterproofing plane of the assembly. Tile is not waterproof and grout is not waterproof — this layer is.

The membrane is only as good as its corners and penetrations. Banding at every internal corner and a collar at every pipe is not optional.
