Watec®Drain KP+

Capillary passive thin-layer drainage system for thin-bed coverings

Information

Watec®Drain KP is the only capillary passive thin-layer drainage system that is laid loose, i.e. without bonding to the substrate. The 100% decoupling and drainage ensures that frost damage and efflorescence are prevented, and speeds up the drying of the structure considerably. The AquaDrain® VARIO box gutter makes it possible to have standard-compliant door thresholds, even with low connection heights.

Advantages

Unique, capillary passive thin-layer drainage mat, laid floating.
Speeds up the drying of the structure by means of a 6 mm layer of air. 100% decoupling protects against cracks in the covering and delamination caused by weather-related shear stresses.
Diffusion slits allow ventilation of residual moisture from cementitious substrates.
The only thin-layer drainage mat with a system drain grate.
Makes standard-compliant reduction of door threshold heights possible.
Unique combination of intelligent special fleece and additional mesh reinforcement.
Special fleece with low through-flow resistance for quick drainage The mesh provides optimum rigidity and adhesion.
Can be used for falls from as little as 1 %.
5 year system warranty.

Brief technical information

Area of application	Privately used walk-on outdoor surfaces such as balconies and terraces and walkways for residential access areas.
Types of covering	Frost-resistant and dimensionally stable coverings and moisture-insensitive coverings for outdoor areas, such as those recommended by the covering manufacturer for the respective usage area and the respective laying method.
Substrates	• Bonded substrates,screeds, concrete surfaces with or without waterproofing, not to be laid directly onto gravel • Old tiles, old coverings
Load-bearing capacity	Surface load capacity up to 3,000 kg/m²; cannot be driven on
Footfall noise improvement	Up to +17dB
Drainage performance	100 % Fall= 2.62 l/(ms) 10 % Fall= 0.78 l/(ms) 1.5 % Fall= 0.28 l/(m*s)
Insulation	Laying Watec® Drain KP+ directly onto thermal insulation is not permitted. Additional load-distributing layers (cement screeds) are required in this case.
