Drainage Channel HYDROblock®

made of cast iron for heavy duty

Load class F 900
Nominal width (mm) 100 | 150 | 200 | 300

The main causes for damage on a drainage channel are – especially in the heavy duty field, horizontal and thrust forces, that depending on the load can cause material fatigue of the channel body, the edge rail an the grates. The drainage channel HYDROblock is made from rugged, ductile cast iron and can be used up to load class F900. The monolithic design with integrated socket seal reduces noise emissions and simplifies a liquid-tight installation.
