Material

The levelling board and the sloped board consist of pressure resistant, expanded polystyrene foam (EPS). The drain body is made of high impact polypropylene (PP). The bonding flange consists of acryl-nitrile butadiene styrene (ABS) and features an attachment flange with a fleece coated surface. The Schlüter®-KERDI collar for bonded waterproofing of the sloped board is a polyethylene waterproofing membrane with fleece fabric laminated on both sides for anchoring in the tile adhesive.

The stainless steel grate included in the waterproofing set Schlüter®-KERDI-SHOWER-SKB is made of V2A (material no. 1.4301 = AISI 304).

Material properties and areas of application
The drain body, bonding flange and grates are categorised as load class K3 in accordance with DIN EN 1253 (BS EN 1253) Gullies for Buildings. This class refers to surfaces without traffic loads, e.g. wet rooms in apartments, nursing homes, hotels, schools, public bathroom and shower facilities. In certain cases, the suitability of the selected floor drainage system must be verified based on the anticipated chemical, mechanical and/or other stresses.
