Information

AquaDrain® SD step drainage systems reliably protect outdoor steps made from ceramic and natural stone/concrete from efflorescence and frost damage caused by accumulated water. They can be used as drainage in a medium bed, on (drainage) mortar or on mortar strips for block steps or drainage mortar in a bond.

Advantages

  • The only single-component drainage system using factory pre-shaped angled elements.
  • Unique intelligent special fleece.
    Will slowly disintegrate after hardening of the laying mortar, preventing the fleece pores becoming blocked by limescale.
  • Drainage provides reliable protection.
    From frost damage and efflorescence caused by accumulated water. Speeds up drying of natural stone
  • Versatile to use.
    Can also be combined with AquaDrain® and Watec® surface drainage mats for terraces with steps leading down.
  • 6 year warranty for specialist companies.
