Application and function

Schlüter-DITRA, in combination with a ceramic or natural stone covering laid in adhesion, constitutes a steam pressure compensation and separation system.

It also allows you to create a waterproofing system for the substrate. The polypropylene sheath has a dovetail-shaped hollow square structure with the innovative “Easyfill” geometry and features an “Easycut” pre-incision grid on the surface.

On the back it is covered with a non-woven fabric.

The support for laying the membrane must be clean, flat and load-bearing. For the application of DITRA, spread a layer of compatible adhesive on the support with a suitable spatula (a notch of 3 x 3 mm or 4 x 4 mm is recommended). The fiber fabric guarantees the mechanical anchoring of the sheath to the underlying adhesive, allowing for good adherence to the substrate. Pay attention to the open time of the adhesive.

The sheath must not remain visible but must be covered with bonded coatings. The anchoring of the adhesive on the upper part of the sheath occurs through the undercut structure of the squares of the sheath. The gluing of the ceramic covering directly on the DITRA must be carried out following the rules of good practice in force.

Features summary:

a) Desolidarisation:
Schlüter-DITRA separates the glue-laid flooring from the substrate, neutralizing the transmission of tension resulting from the different expansions between the substrate and the covering, which are therefore not transmitted to the flooring. On critical substrates it also acts as a bridge over the cracks, thus preventing them from reaching the surface layer.

b) Waterproofing:
Schlüter-DITRA is a waterproof polypropylene sleeve with high vapor barrier capacity. In combination with a ceramic or natural stone glued covering, it is possible to create a waterproofing system that protects the substrate from damage caused by the penetration of humidity. In this case the joints, the connections with walls and fixed elements and the closure of the open sides of the sheath must be made following the instructions in this technical data sheet. Classes of exposure to water: W0-I to W3-I according to DIN 18531-5 E 18534. The system is also supplied with abP certification*.

c) Steam pressure vent:
The intercommunicating channels on the back of Schlüter-DITRA allow the compensation of the vapor pressure deriving from damp substrates.

d) Load distribution:
On the floor, the DITRA sheath must be covered with ceramic tiles of a size, thickness and compressive strength suitable for the intended use and in any case with a size of no less than 5 x 5 cm and a thickness of no less than 5.5 mm. The sheath homogeneously distributes the loads present on the floor through the square cavities filled with glue and separated from each other by hollow ribs, transferring them directly to the support. For this reason, floors laid on DITRA are so resistant. When choosing the format, thickness and compressive strength of the ceramic, to ensure adequate resistance, account must be taken of the stresses to be expected, for example the possible presence of high static and/or dynamic loads (e.g. in commercial or public) and/or important point loads (e.g. grand pianos, shelving, pallet trucks). In this regard, we note the provisions of the ZDB in force in Germany regarding the laying of “Ceramic floors with high mechanical resistance”. In areas subject to high loads, pay particular attention to completely fill the cavities between the sheath and the tile and ensure full bed laying of the ceramic over the sheath. It is good practice to protect ceramic flooring from knocks with hard objects.

e) Tear resistance:
Through the mechanical anchoring that is created under the sheath between adhesive, non-woven fabric and support and, above the sheath, between adhesive and square cavities, Schlüter-DITRA establishes a good adhesion of the ceramic coating with the support. Schlüter-DITRA can be used for both walls and floors. For wall installation, the use of dowels for additional anchoring may be indicated.

Functions

Schlüter-KERDI-CID are waterproofing kits for capillary interruption in the floor in the door passage area according to DIN 18534. The kits differ according to the door opening direction, inwards or outwards . The kit components are a Schlüter-SCHIENE-E with KERDI-KEBA sealing strip and corresponding KERDI-KERECK preformed corners. The profile can be shortened to adapt it to different door dimensions. The components are glued using KERDI-COLL (not included in the scope of delivery).

The DIN regulations for waterproofing interior spaces require the protection of adjacent, non-waterproofed rooms from water produced in wet areas, even in door areas. The Schlüter-KERDI-CID kits enable capillary interruption for passage areas in different door opening directions.

The advantages:

• Safe system
• Proven stainless steel clasp
• Kit with preformed pieces included

Application and functions

Schlüter-KERDI-LINE-VARIO is a linear waste system that can be shortened to the desired length for creating floor-level showers with ceramic tiles, natural stone or other coverings.

The KERDI-LINE-VARIO horizontal drain consists of a drain body and an adapter. The waste body is characterized by an extremely flat sinusoidal outlet that can be swiveled through 360° with an integrated odor trap. Its sinusoidal shape favors a high flow rate of the water in the floor drain thus obtaining a self-cleaning effect.

The acoustic deadening element included in the kit prevents the noise from the drain body from being transmitted to the adjacent walls or floor. It also performs the function of positioning guide in case of installation directly against the wall. The adapter with integrated Schlüter-KERDIFLEX plug is supplied already inserted into the sinusoidal drain in such a way as to guarantee its tightness and is fixed to a circular clamp. By loosening the circular clamp it is possible to rotate the sinusoidal drain by 360° in order to be able to connect the drain to the building drain, whatever the situation that arises on site.

In the KERDI-LINE-H 50 the drain adapter can be adjusted in height according to the requirements of the building site.

The KERDI-LINE-VARIO outflow profiles are available in two different designs. They can be cut to the desired size up to a minimum length of 22 cm and adjusted in height. They are supplied with 2 special closing terminals.

Schlüter-KERDI-LINE-VARIO COVE is a drainage profile with a visible groove and can be cut to the desired length. It is equipped with a visible slot, only 8 mm wide and 140 mm long. It is optionally available in V4A stainless steel or powder-coated aluminum with a TRENDLINE finish and in lengths of 120 cm and 180 cm.

Schlüter-KERDI-LINE-VARIO WAVE is a flow profile with W-groove and can be cut to any desired length. This profile is also available optionally in V4A stainless steel or powder-coated aluminum with TRENDLINE finish and in the lengths 120 cm and 180 cm.

In the painted aluminum version the profiles are available in two widths: 34 mm and 42 mm. In the slimmest version, the central exhaust slot is just 14 mm wide and 140 mm long. In the 42 mm wide version, the discharge slot is 24 mm wide and 140 mm long and offers a suitable space for inserting an optional hair filter.

In the stainless steel version, the profile is 42 mm wide, the discharge slot is 25 mm wide and 140 mm long and also offers a space suitable for inserting an optional hair filter.

All KERDI-LINE-VARIO WAVE profile versions are equipped with a matching removable cover in the middle. Find the images on p. 7

The KERDI flexible plug, already integrated in the drain adapter, guarantees a perfect connection between the channel and the horizontal and vertical waterproofing system. The construction site protection in transparent plastic guarantees its integrity during the assembly phase.
Combined with the waterproofing systems Schlüter-KERDI, Schlüter-DITRA, Schlüter-DITRA-HEAT or Schlüter-KERDIBOARD with the relative adhesives Schlüter-KERDI-COLL or Schlüter-KERDI-FIX, the KERDI-LINE channels become part of a certified system with abP test (allgemeines bauaufsichtliches Prüfzeugnis), compliant with German standard DIN 18534. The moisture resistance classes according to abP can be found in the relevant data sheets. In accordance with ETAG 022 (sealing in combination with other materials), Schlüter-KERDI-LINE is a system component with European approval (ETA = European Technical Assessment). The aforementioned Schlüter products certified with KERDI-LINE carry the CE mark.

Note:
KERDI-LINE-VARIO requires the creation of a screed on site. The screed made on site is waterproofed on the surface, preferably with DITRA (technical data sheet 6.1) or with -DITRA-HEAT (technical data sheet 6.4). The Schlüter-SHOWERPROFILE-S and -R profiles allow the lateral closure of the sloping shower surface towards the non-inclined floor and/or the wall (data sheet 14.1). To allow adequate closure of the lateral differences in height, the SHOWERPROFILE-S profiles are wedge-shaped. The adjacent walls are waterproofed with KERDI (technical data sheet 8.1) or with KERDI-BOARD (technical data sheet 12.1).
