Trenchless rehabilitation using a hat liner
We use hat liners to repair leaks at connection points between service pipes and the main pipe. This is suitable for addressing leaks caused by ill-fitting connecting pieces, as well as those resulting from an unprofessional connection of the cut-out. Long-term positive customer experience attests to service line restoration of the highest standard.
Hat liner packers can be used for service pipes of DN 100–200 mm fitted to the main pipeline at an angle ranging from 45° to 90° to its axis. The method accommodates main pipeline diameters of DN 250–600 mm.
We hold EN ISO 9001:2008 and EN ISO 14001:2004 quality certification.
