Background

The number of manhole and sewer structures in need of repair is steadily increasing. Leaks in the wastewater system cause infiltration which puts excessive strain on our wastewater treatment plants, reducing their treatment performance significantly. Due to exfiltration toxic substances permeate into the surrounding soil, which frequently causes heavy contamination and the groundwater which in itself may also not be safe.

Ombran System Solution

Attacks from biogenic sulphuric acid corrosion (BSAC) and dynamic stress are responsible for heavy damages to manhole and sewer structures in addition to the aggressive wastewater itself. The reliable repair of such defects pose high demands on engineers, applicators and the product systems used. Only a specifically tailored repair system will ensure the success of the repair and guarantee a lasting protection of the structures.
