Schluter DITRA DRAIN 4 Drainage and Uncoupling Membrane (Select Size)

Schlüter®-DITRA-DRAIN is a safe and permanently effective passive capillary drainage system for Floor assemblies. The material is installed in exterior areas into thin bed Adhesive over a sloped waterproofing assembly, such as Schlüter®-KERDI or other suitable proprietary waterproofing systems. Schlüter®-DITRA-DRAIN 4 consists of a closed polyethylene foil that on one side features approx. 4 mm high, truncated conical studs with a laminated filter webbing. Some of these studs are shaped as approximately 2 mm high inverted truncated pyramids, which form square undercut chambers on the underside. These facilitate the bonding of the thin bed mortar, which is applied with a notched 6 mm x 6 mm trowel on the bonded waterproofing assembly for fully embedding Schlüter®-DITRA-DRAIN. The closely adjoining studs in the form of truncated cones are able to absorb high compressive forces (up to approx. 50 t/m2). The undercut design of the truncated pyramid studs allows for excellent bonding with the substrate. Schlüter®-DITRA-DRAIN 4 is Particularly suited for interior areas and small exterior areas. Schlüter®-DITRA-DRAIN 8 consists of an impact resistant polyethylene foil with a special truncated stud structure on one side and polypropylene filter webbing laminated on both sides. The laminated filter webbing on the underside facilitates the bonding of the thin bed mortar, which is applied with a notched trowel (recommended: 3 x 3 mm or 4 x 4 mm) on the bonded waterproofing assembly for fully embedding Schlüter®-DITRA-DRAIN 8. The compressive yield strength is up to 15 t/ m². Schlüter®-DITRA-DRAIN 8 is suited for exterior areas and Particularly for stairs and Larger balcony and terrace areas with longer drainage paths. It is especially important to keep this drainage separate and to not run it along the stairs. Stair assemblies are subject to special requirements. Please contact us for further inFormation if you are planning this type of project. The closed polyethylene membranes Schlüter®-DITRA-DRAIN 4 and 8 form an additional protective layer for the waterproofing assembly.
