Sustainable rehabilitation of sewer shafts.

Sewer shafts are exposed to permanent and recurring loads for many years. A defective shaft may be of concern for the environment and surroundings for several reasons at once. Dirty water escaping from the sewer can contaminate the groundwater. Water entering the system can pollute sewage treatment plants. There is also a risk that shaft covers will sink below the level of the surrounding area (e.g. a roadway).

THORN Abwassertechnik specialises in the rehabilitation of shafts and provides you with quick, durable, and reliable solutions.
