AquaDrain® T+ provides quick and permanent drainage of the covering structure. It prevents fouling and silt formation, which often occur with loosely laid coverings.


  • Special fleece with low through-flow resistance.
    Ensures quick drainage of seepage water and avoids fouling on the waterproofing.
  • The best drainage results.
    In comparison to other standard drainage mats (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).
  • Damage-free since its introduction in 1987.
    At up to 25 mm, AquaDrain® T+ raises the surface higher than any other drainage mat and keeps its anti-capillary function, even if there are puddles of water on the waterproofing.
  • Up to +33 dB footfall noise improvement.
    (Research by Construction Acoustics Laboratory, University of Rhine-Main).
  • The contact area of 66 % provides favourable load distribution with no high point loads.
  • 6 year warranty for specialist companies.
