Anwendung und Funktion
SchlupfltersupregsupDITRADRAIN is a safe and permanently effective capillary passive composite drainage system. The installation in exterior areas is carried out in a duumlnnbettmoumlrtel over a composite waterproofing layer applied in the frame, such as SchlupfltersupregsupKERDIppbr.
SchlupfltersupregsupDITRADRAIN 4 consists of a closed polyethylene film with approximately 4 mm high conical stub-shaped protrusions on one side, on which a filter fleece is laminated. Some of the protrusions are formed from inverted pyramidal stumps approximately 2 mm high, creating quadratically undercut chambers on the underside. These chambers serve to anchor the duumlnnbettmoumlrtel, which is applied with a 6 x 6 mm serration onto the composite waterproofing and is fully embedded in the SchlupfltersupregsupDITRADRAIN. The closely spaced conical stub-shaped protrusions can withstand very high pressure loads up to 50 t/m². The undercut pyramidal stub-shaped protrusions ensure good adhesion to the substrate.
SchlupfltersupregsupDITRADRAIN 4 is particularly suitable for interior areas and small areas in exterior applications.
Summary of functions and applications
The composite construction consists of a base layer of a composite waterproofing as a laying substrate, onto which the SchlupfltersupregsupDITRADRAIN is glued, and the directly installed surface layer in the duumlnnbettmoumlrtel. This results in a construction with high load-bearing capacity that meets the requirements for waterproofing as well as passive drainage, ventilation, and decoupling.
Drainage and Ventilation
The ventilation allows for rapid drying of the duumlnnbettmoumlrtel. The capillary passive drainage effect ensures pressureless removal of water accumulating in the drainage space and prevents backflow into the surface layer.
Decoupling
SchlupfltersupregsupDITRADRAIN decouples the surface from the substrate, thereby neutralizing tensions between the substrate and the tile covering, which result from different deformation behaviors. It also bridges tension cracks from the substrate and prevents them from transferring into the tile covering.
If the installation substrate does not require waterproofing, e.g., on drained screed or earth-contact construction, SchlupfltersupregsupDITRADRAIN with functions of drainage, ventilation, and decoupling can also be directly glued onto the substrate with duumlnnbettmoumlrtel.
Substrates on which SchlupfltersupregsupDITRADRAIN is to be installed must generally be checked for flatness, load-bearing capacity, adhesion, and material compatibility. Surface contaminants that impair adhesion must be removed. If leveling of unevenness or a height or frame adjustment is necessary, this must be done before applying the waterproofing and laying SchlupfltersupregsupDITRADRAIN.
For use of DitraDrain 4, a norm-compliant hydraulically setting duumlnnbettmoumlrtel with a 6 x 6 mm serration is applied. For DitraDrain 8, 3 x 3 mm or 4 x 4 mm is recommended. The choice of duumlnnbettmoumlrtel to be glued with SchlupfltersupregsupDITRADRAIN must be compatible with the substrate.
When using tile materials with a side length of ? 30 cm, a crystalline water-binding tile adhesive is recommended for rapid strength development and drying of the mortar.
The pre-cut SchlupfltersupregsupDITRADRAIN rolls are embedded in the applied adhesive and immediately pressed fully into the duumlnnbettmoumlrtel with a notched trowel or a pressing roller. For SchlupfltersupregsupDITRADRAIN 4, ensure that the inverted pyramidal chambers are filled with mortar after installation. The open time of the adhesive must be observed.
It is advisable to tension the SchlupfltersupregsupDITRADRAIN rolls slightly when laying, to ensure straight alignment under light tension. The individual rolls are laid end-to-end with overlaps, and the fleece edges are overlapped.
Cut edges where the fleece edge is missing are sealed with the self-adhesive SchlupfltersupregsupDITRADRAINSTU. To prevent damage to the installed SchlupfltersupregsupDITRADRAIN or detachment from the substrate during work, it is recommended to protect it, e.g., by laying planks, especially in the traffic zone for material transport. Protective measures, e.g., against direct sunlight or precipitation in exterior areas, may also be necessary.
Immediately after gluing the SchlupfltersupregsupDITRADRAIN, tiles or natural stone coverings can be properly installed in the duumlnnbettmoumlrtel method. The surface material must be embedded as fully as possible. The notch depth of the trowel must be matched to the tile format. The open time of the duumlnnbettmoumlrtel must be observed. In exterior areas, the hydraulic duumlnnbettmoumlrtel and the surface material must be waterproof and weather-resistant.
After walkability, the surface can be grouted with an appropriate joint mortar. The drainage space at the edge must be covered with a profile, e.g., SchlupfltersupregsupBARART, or a side plate, without sealing the drainage joint.
For movement joints as field boundaries, edge and connection joints, the relevant instructions in this data sheet and the applicable professional rules must be observed.
Note: For edge terminations, movement joints, and wall connections, we refer to our profile types SchlupfltersupregsupBARA and SchlupfltersupregsupDILEX.
