Movement or expansion joints require special consideration, even when using KERDI waterproofing membranes or DITRA mats. KERDI-FLEX polyethylene band, which comes in two widths, and KERDI-COLL-L adhesive provides reliable waterproofing of these joints. The sealing band and KERDI-FIX adhesive also create a sealed connection to structural components, such as bathtubs or shower trays. The fleece surface of KERDI-FLEX ensures a reliable bond with whatever adhesive is used.
