MorTec® DRAIN is a thin-layer epoxy resin drainage mortar system for use in combination with AquaDrain® EK surface drainage and AquaDrain® SD steps drainage for solid laid natural stone and ceramic coverings on balconies and (roof) terraces.


  • Thin-layer:
    reduces the required construction height by at least 25 mm compared to mineral drainage mortar systems (approx. 50-70 mm construction height). This makes it ideal for renovation work or if there is a lack of construction height.
  • Reliable:
    In combination with the drainage systems, MorTec® DRAIN supports rapid drainage and speeds up the drying of natural stone coverings. The complete system including AquaDrain® drain grates also guarantees optimum drainage of the threshold area.
