Schluter®-DITRA-DRAIN/-STU

Schluter®-DITRA-DRAIN is a drainage membrane designed for use within thin-bed ceramic and stone tile assemblies in exterior applications. It consists of a studded polyethylene sheet with a laminated polypropylene filter fabric. DITRA-DRAIN provides uncoupling and drainage for use in a variety of exterior applications, including exterior floors, patios, walkways, and balconies.

DITRA-DRAIN-STU is a self-adhesive tape designed to seam the cut edges of the DITRA-DRAIN membrane. The seaming tape provides a way to continue the filter fabric at the top of the membrane and allow for ventilation and drainage.
