Schluter KERDI LINE H Linear Drain

£221.64£456.62 (inc VAT)



The Schluter KERDI LINE H Linear Drain is a component linear drainage system for the construction of floor level showers with ceramic tiles, natural stone, or other coatings. It consists of a deep-drawn stainless steel channel body as well as a grate and frame top section that can be seamlessly adjusted to the thickness of the covering with the help of the installation aid included in the set.

The Schluter KERDI LINE H Linear Drain features a horizontal drain with an integrated odour trap, that can be positioned at intermediate or perimeter locations in the floor. Available with a DN40 (40mm) or DN50 (50mm) diameter outlet pipe. The DN40 Version has an installation height of 78mm, and the DN50 Version has an installation height of 97mm.

The Schluter KERDI LINE H Linear Drain is available in lengths from 500mm to 1800mm, in 100mm increments. This length value refers to the internal size of the channel trap – the external length of the body is 50mm more for each size, due to the 25mm flange that runs round the entire top edge of the channel body. This flange comes pre-adhered with a sealing collar made of Schluter KERDI 200 Membrane. It ensures the reliable connection of the channel body to the bonded waterproofing assembly, both in the floor area and on upright walls. It can be universally used for intermediate installation in floor or at wall areas.

The Schluter KERDI LINE H Linear Drain is designed to be combined with the KERDI LINE Standard, KERDI LINE STYLE Contour Grate/Frame Sets and the KERDI LINE D frameless tile cover support, which are purchased separately.

When the Schluter KERDI LINE H Linear Drain is used in conjunction with the waterproofing systems Schluter KERDI 200 Membrane, Schluter DITRA 25 Matting, Schluter DITRA HEAT Matting or Schluter KERDI BOARD and the associated system sealing adhesives Schluter KERDI COLL L or Schluter KERDI FIX, this results in certified bonded waterproofing assemblies with a connected linear drainage.

The Schluter KERDI LINE H Linear Drain can also be used with the Schluter pre-formed sloped linear shower trays – Schluter KERDI SHOWER LT/LTS Shower Trays.

The Schluter KERDI LINE H Linear Drain channel bodies with lengths up to 1200 mm are made of formed stainless steel V4A (material no. 1.44404 = AISI 316L). For lengths of 1300 mm to 1800mm, they are made of angled and welded stainless steel V4A (material no. 1.44404 = AISI 316L). The channel bodies feature an adhesive flange with a factory-attached Schluter KERDI collar on the surface. This is a soft polyethylene waterproofing membrane with fleece fabric laminated on both sides. Depending on the type, drain bodies are made of high-impact polypropylene (PP) or acrylonitrile butadiene styrene (ABS). The odour trap is made of fibre-reinforced polypropylene (PP).

Schluter KERDI LINE H Linear Drain Installation:

  1. The channel support is installed on a level substrate with the appropriate height. To offset uneven sections or for height adjustment, the channel support may also be installed and aligned over several, sufficiently spaced spots of mortar or on a full layer of levelling screed. For wall installation, the channel body must be aligned in accordance with the thickness of the wall covering. For intermediate installation, use the supplied filling strip to create symmetrical dimension for the channel support.
    Note: To improve sound insulation in shower areas, install the insulating membrane Schluter KERDI LINE SR and place a perimeter insulation strip along the edge area. Install the sound insulation membranes loosely on the level, solid ceiling with abutting seams. The printed side must be facing up. To avoid sound bridges, the seams can be covered with the seaming tape Schluter DITRA SOUND KB. See the planning basis for further installation details of certified system assemblies – in accordance with noise insulation requirements of the corresponding standards and regulations.
  2. Fit the channel body into the channel support together with a custom cut drain pipe for connecting to the drainage system of the building. Perform a leak test.
  3. Next abut the sloped tray Schluter KERDI SHOWER L, together with the levelling board if necessary , to the precisely installed Schluter KERDI LINE H drainage channel at the correct height, flush with the upper edge of the channel support (see Product Data Sheet 8.8). As an alternative, you can also install a sloped screed at the correct height that is flush with the upper edge of the channel support. Schluter BEKOTEC DPS Dry Pack screed can be used for creating the sloped screed requirements.
  4. To integrate the Schluter KERDI collar, apply the sealing adhesive Schluter KERDI COLL L to the adjoining waterproofing assembly with a 3 x 3 mm or 4 x 4 mm notched trowel and completely embed the Schluter KERDI collar in this assembly. Observe the curing times of all materials. Use Schluter KERDI COLL L to tightly seal the wall connections with Schluter KERDI KEBA.
    Installation with low construction height: Schluter KERDI LINE H is designed for horizontal drainage on the floor level. If drainage is to go through at floor level, an installation height of ≥ 22 mm can be achieved with the Schluter KERDI LINE V Linear Drain.
