Watec®Drain KP+

The unique, passive capillary thin-layer drainage

Watec®Drain KP+

Unique, capillary passive thin-layer drainage
for thin layer, floating laid ceramic tiles and natural stone. 

Watec®Drain KP+ is the only capillary passive thin-layer drainage system that can be laid loose, that is to say without bonding to the substrate. The 100% uncoupling and drainage ensures the prevention of frost damage and efflorescence caused by accumulated water and considerably speeds up the drying of the structure. The Watec®Drain RD drainage gutter allows for standard-compliant door threshold connections even at low connection heights.
