Advantages of AquaDrain® TM

  • Reliable drainage of outdoor surfaces and thresholds at construction heights of only 30 mm.
    AquaDrain® TM in a system with the TerraMaxx® laying process allows for total heights from 30 mm including covering, e.g. for renovation projects.
  • Integral dirt trap protects against fouling.
    The dirt trap prevents dirt falling into the drain gutter, guaranteeing the permanent performance of gutter and surface drainage.
  • Easy height adjustment thanks to 6 continuously adjustable screw feet.
    Precise, easy and time-saving adjustment to the level of the covering.
  • Maximum drainage performance thanks to drain grate open below.
    In combination with the TerraMaxx® laying process or Watec® thin-layer drainage in front of parapets, the system guarantees maximum drainage without water accumulation. Façade and surface water is shed without impediment and safely into the surface drainage under the covering.
