Wet-room waterproofing under tiles
Waterproofing membrane under ceramic tiles or natural stone in bathrooms, showers and other wet areas. The catalogue requires tile adhesives classified C2TES1 or higher on top of HYDROCEM and MARMOCEM LAST; the adhesive layer lists the MARMODOM cementitious adhesives classified C2TES1 or C2TES2.
Bathrooms & wet rooms

Notes on this system
- HYDROCEM page lists terraces, balconies, pools and floors, not bathrooms explicitly; included per the C2TES1 under-tile statement
- MARMOCEM LAST is also stated usable 'before laying tiles or natural stones' but is not included here
- HYLASTIC EPU (R2T reaction resin) is listed over these membranes in the pool diagram (p27) but is not a C2TES1+ cementitious class, so it is left out
