For bonded waterproofing system you can choose a polymer-mortar sealing film or the epoxy sealing. Both can be used with the sealing tapes and collars. Liquid-applied products for waterproofing purposes and tested in compliance with EN 14891 feature a crack-bridging ability. They produce a stress-compensating bond between screed and tile adhesive.
SEALING TAPES FOR JOINTS, CORNERS, PIPE INLETS AND DRAIN OPENINGS
It is recommended to embed waterproofing tapes and collars in all corners, around joints and openings (shower and bathtub drains). For this purpose use Ceresit CL 82 Ultratape, Ceresit CL 152 Sealing Tape and Ceresit CL 83 Sealing Collar.
The sealing tapes and collars should be embedded in the first layer of liquid waterproofing and covered with the second one.
