For reliable waterproofing at challenging corners in wet rooms, we recommend KERDI-KERECK. The precut sections are made of the same polyethylene as the proven KERDI membranes and have a fleece laminated on both sides for optimal anchoring in the tile adhesive. KERDI-KERECK can be shaped as necessary to create internal or external corners and comes in sets of five. It is even suitable for waterproofing corners that are not completely square.
