AquaDrain® SD
Unique passive capillary steps drainage

Unique capillary passive steps drainage system
for outdoor steps with ceramic or natural stone/concrete paving.
AquaDrain® SD steps drainage systems reliably protect outdoor steps with ceramic and natural stone/concrete paving from efflorescence and frost damage caused by accumulated water. This can be used for drainage in the middle bed, on (drain) mortar or on strips of mortar for block steps, or on drain mortar in a bond.
