Schlüter®-DITRA-DRAIN | Material | Schlüter-Systems



Schlüter-DITRA-DRAIN 4 consists of an impact resistant polyethylene foil with a special stud structure on one side and polypropylene filter webbing laminated on the upper side. The compressive yield strength of Schlüter-DITRA-DRAIN 4 is up to 50 t/m2. 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 compressive yield strength of Schlüter-DITRA-DRAIN 8 is up to 15 t/ m2. The material of Schlüter-DITRA-DRAIN is dimensionally stable up to a temperature range of + 80° C.

The functionality and material properties are guaranteed to last. The material is nonageing and rot-proof. Cutting waste is not classified as hazardous waste. Polyethylene is not UV stable in the long term; the product should not be stored in places with prolonged exposure to direct sunlight.

The thin bed adhesive and the covering materials used in conjunction with Schlüter-DITRA-DRAIN must be suitable for the corresponding application and meet the applicable requirements. In outdoor areas, such materials must be waterproof, frostproof and weather resistant.

The ZDB information sheet “Tiled assemblies in outside areas” states: “Natural stone and concrete pavers may vary in colour due to differences in the drying process.” This covering specific occurrence cannot be completely ruled out for the covering assembly described in this product data sheet. We recommend pointing this out to the homeowner or developer when selecting the covering materials. The product creates a layer of air between the covering and the substrate, which separates the layers. The covering material must be selected in the appropriate thickness to withstand the expected compressive forces. As a rule, the impact of hard objects must be avoided on tile and stone coverings. For residential areas and moderate commercial use, the minimum tile size for use with Schlüter-DITRA-DRAIN 4 is 5 x 5 cm, with a minimum thickness of 5 mm. Schlüter-DITRA-DRAIN 8 supports a minimum size of 10 x 10 cm with a minimum thickness of 8 mm. For application areas in private homes or with moderate commercial use, the selected tiles should be at least 5 x 5 cm in size and 8 mm thick.

Due to the special characteristics of the system, coverings installed over Schlüter- DITRA-DRAIN may have a hollow sound when they are walked upon with hard shoes or tapped with a hard object. Due to the differing expansion coefficients of the covering and the grout material, microfine cracks in the joints cannot be completely ruled out.
