The AquaDrain® DR-HB has been specially developed for drained structures with the drive-on AquaDrain® HB AquaDrain® HU-EK surface drainage mats in order to now also provide line drainage which takes in and systematically drains the surface water and also the seepage water which penetrates via the joints in the covering.


  • Perfect in the system with AquaDrain® HB and AquaDrain® HU-EK
    Prevents dirt from blocking the floor gully, therefore guaranteeing the permanent drainage performance.
  • The integral dirt trap protects against fouling.
  • Simple, precise alignment at covering level using continuously adjustable screw feet.
    Guarantees unimpeded drainage of surface water in floor gullies.
  • Maximum drainage performance thanks to drain grate which is open at the bottom.
  • Grate locking
  • Easy inspection thanks to removable grate cover.
