AquaDrain® EK is an anti-capillary surface drainage mat which has been specially designed for laying outdoor coverings on drainage mortar. Thanks to the unique mesh, the raising of the entire surface and a high drainage volume, the system provides rapid and immediate drainage.


  • Laminated mesh raises the entire covering – for a long-term high-quality drainage function.
    The only mesh with tested long-term durability (research by German Materials Testing Institute (MPA), Darmstadt).
  • The quickest draining of seepage water on the waterproofing layer.
    More than 100 times faster than drainage/single grain mortar alone (kiwa German Institute for Textile Construction and Environmental Technology (tBU), Greven).
  • Anti-capillary function provides reliable protection.
    Proven to eliminate frost damage, efflorescence and moisture stains caused by accumulated water (Research by German Materials Testing Institute (MPA), Darmstadt).
  • Up to + 30 dB footfall noise improvement.
    (Research by Construction Acoustics Laboratory, University of Rhine-Main).
  • Can also be used for large-size formats outdoors.
  • 6 year warranty for specialist companies.
