AquaDrain® SR-U slit gutters can be unobtrusively integrated into the covering. Unlike conventional slit gutters, the gutter body is open on the underside and provides reliable, quick surface water removal directly into the drainage layer.


  • Uniquely slender.
    Made from powder-coated aluminium, only 15 mm wide on the visible side.
  • Continuous height adjustment from 65 mm to 110 mm thanks to provided universal foot set
  • Can be used in a flexible way.
    Installation in front of parapets/rising structures in the line or in combination with the TerraMaxx® RS frame system
  • Innovative reversible cover.
    The reversible stainless steel cover also acts as a dirt trap and prevents leaves or dirt from fouling the drainage layer and reducing drainage performance.
    Thanks to the possibility of reversing the cover, a subtle shadow gap appearance or visible flush line drainage can be realised.
  • Faster drainage that previous slit gutters.
    Drainage openings on the underside drain water quickly and reliably into the attached surface drainage.
  • Low installation height from 65 mm.
