Watec technical data / installation guide (ARDEX)Watec product overview (ARDEX)ARDEX WatecDrain KP+ Drainage Mat 1 × 2 m
1 × 2 m sheet · Polypropylene · Underlayment
A low-profile polypropylene drainage mat for the ARDEX Watec exterior system, laid loose over the membrane with tile or stone set directly on top in a thin-bed mortar. Its channels and air layer let water escape and the bed dry out, which helps prevent efflorescence, staining and debonding where build-up height is limited.
What it’s used for
- Exterior tile and stone with limited construction height
- Balconies, patios and decks
- Over pre-sloped (1.5–2%) concrete or wood
- Thin-bed setting with ARDEX X 90 OUTDOOR or X 32
