The new ray of hope for underground repairs

Obduramus Umwelttechnik GmbH is active in the field of environmental engineering and develops and produces solutions for sewer rehabiliation. Our products provide solutions for a very diverse range of damage types within pipes.

Conventional sewer rehabilitation methods (digging) can present significant challenges for local authorities, as well as their contracted consulting engineers and repair organizations. For example, if important transport infrastructures are impacted by construction, coordination costs can be considerable.

Obduramus has developed alternative trenchless repair solutions which reliably and permanently seal pipe damages internally. Our Circum technology consists of a stainless steel sleeve surrounded by an EPDM rubber seal, both to be pressed against the inner pipe wall via an inflatable packer until sealing occurs and then to remain permanently locked in place by a strong mechanical lock. Different sealing processes and diameters are available. With this trenchless system a damaged pipe can be repaired within minutes, instead of many hours or several days.

Their benefits:

Permanent sealing purely based on the principles of mechanics
