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 Watec®Drain RD drain gully makes it possible to have standard-compliant door threshold connections, even with low connection heights.
Unique, capillary passive thin-layer drainage mat, laid floating.
A 6 mm layer of air speeds up the drying of the structure.
100% decoupling provides protection from cracks in the covering and delamination due to weather-related shear stress.
- 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.|
• Bonded substrates, 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|
|Fall-related drainage capacity||
100 % = 2.62 l/(m*s)
10 % = 0.78 l/(m*s)
1,5 % = 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 here.|
