Waterproofing, Drainage, Sound Insulation, Uncoupling & Tanking Membranes
Schlüter-Systems' range of mattings and membranes are designed to waterproof and protect tiled installations from lateral movement, cracked substrates and water penetration.

Schlüter-DITRA has been a proven solution for uncoupling and bonded waterproofing for almost 20 years. As the first passive capillary bonded drainage product, Schlüter-DITRA-DRAIN uncouples and ventilates the coverings of balconies, terraces, and wetrooms. Additionally, the sound insulation mat Schlüter-DITRA-SOUND significantly reduces the sound transmission to adjoining rooms.

Wetroom drainage, waterproofing (also known as tanking), uncoupling products
  Schlüter®-SHOWERPROFILE-S / -R

Schlüter®-SHOWERPROFILE-S is a two part profile with a tapered edge, designed to cover adjoining tile edges that become exposed as the shower floor slopes to accommodate drainage to the Schluter®- KERDI-LINE.


Schlüter-KERDI-SHOWER is a modular system for the construction of floor level showers with ceramic or natural stone tiles. The sloped boards are available in four different dimensions and can be combined with sets for waterproofing the walls and floor drains, with optional use of levelling panels.


Schlüter-KERDI-DRAIN is a floor drain system for the easy and reliable connection of drainage systems to bonded waterproofing assemblies.


Schlüter-KERDI-SHOWER-L is a sloped tray of pressure resistant polystyrene with a matching optional levelling board of rigid XPS foam.

  Schlüter-KERDI-LINE-H /-V

Schlüter-KERDI-LINE is a component linear drainage system for the construction of floor level showers with ceramic tiles, natural stone, or other coatings.

  Schlüter®-DITRA 25

Schlüter-DITRA 25 is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration and an anchoring fleece laminated to its underside. Designed for tile and natural stone installations, Schlüter-DITRA 25 serves as a waterproofing membrane, a vapour pressure equalisation layer to accommodate moisture occurring at the underside of the substrate and an uncoupling layer for problematic substrates.


Schlüter-DITRA-HEAT is a polypropylene membrane with a cut-back stud structure and an anchoring fleece laminated on the underside. It is a universal substrate for tile coverings, which serves as an uncoupling layer and vapour pressure equalisation layer and is designed for the attachment of heating cables.


Schlüter-DITRA-DRAIN 4 is an impact resistant polyethylene mat with a special stud structure on one side and a polypropylene filter webbing laminated on the upper side. It is a universal substrate for tile coverings, which serves as an uncoupling layer and a permanently effective passive capillary drainage mat.
Schlüter-DITRA-DRAIN 8 is an impact resistant polyethylene mat with a special stud structure. It features a fl eece fabric on the underside for bonding with the tile adhesive and a special fi lter fl eece on the top. Schlüter-DITRADRAIN 8 is a universal substrate for tile coverings, which serves as an uncoupling layer and a permanently effective passive capillary bonded drainage mat.


Schlüter-DITRA-SOUND is a bonded impact acoustic matting sound insulation for tile coverings, made of a heavy polyethylene mat, which has an anchoring fleece laminated on both sides to bond with the tile adhesive. Schlüter-DITRA-SOUND reduces the impact sound of floor constructions by 13 dB (test values according to DIN EN ISO 140-8).


Schlüter-KERDI is a polyethylene, waterproofing mat with an anchoring fleece on both sides. It is suitable for waterproofing in conjunction with tiled surfaces on walls and floors. The high water vapour diffusion resistance of Schlüter-KERDI-DS makes it suitable as a vapour barrier in bonded floor assemblies with tile coverings.


Schlüter-KERDI-FIX is a MS polymer based elastic adhesive. It is suited for adjoining and sealing the abutments and joint areas of Schlüter-KERDI waterproofing membrane sections.


Schlüter-KERDI-COLL is a two component sealant adhesive based on a solvent free acrylate dispersion and a reactive cementitious powder.

Drainage systems

Schlüter-KERDI-DRAIN-SP-E is a stainless steel spout for draining balconies and terraces that are enclosed by a parapet. Schlüter-KERDI collar is attached to the large adhesive flange as a waterproofing connection. This allows for the simple and safe connection to waterproofing assemblies.


Schlüter-TROBA is a separation and drainage layer for use above a horizontal waterproofing layer and below a screed or gravel layer. It consists of a pressure stable polyethylene sheet with perforated studs for reliable drainage. Tile applications above screeds require the installation of Schlüter-DITRA as an uncoupling and waterproofing membrane.


Schlüter®-TROBA-PLUS is a durable and reliable sub surface drainage system that prevents the possibility of capillary action. The closely positioned cone shaped studs can withstand heavy loads and are covered by a water permeable fleece webbing. The studded mat raises the entire surface assembly, creating a continuous drainage area.


Schlüter®-TROBA-STELZ-MR are plastic rings that provide assistance in laying large format pavers on balconies and terraces. The 25 mm high plastic rings are positioned at the cross joints where the pavers meet and filled with mortar.


Schlüter-TROBA-LINE-TL is a stainless steel drainage channel that can be placed at low levels to doorsills or wall connections on balconies and terraces to prevent water accumulation. This can also be used as an area drainage channel.


Schlüter-TROBA-STELZ-DR are plastic casting mould rings of non-rotting polyethylene that are used as installation aids for large format pavers on balconies and terraces.
