MorTec® DRAIN-ZE drainage mortar is a cement-based drainage mortar for use on TerraMaxx® DS drain raised floor supports, AquaDrain® EK and HU-EK surface drainage systems and on AquaDrain® SD step drainage systems.


  • Dry mortar:
    Mixing ratio consistency is guaranteed by mixing in the factory. It can therefore be processed more reliably and quickly than on-site mixtures. Additives improve the processing and product characteristics.
  • Reliable:
    In combination with the drainage systems, MorTec® DRAIN-ZE 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.
