The company WOMBAT, s.r.o. has several modern no-dig technologies at its disposal. It is possible to rehabilitate damaged sewer pipes without a need of a linear excavation. Building site is situated only around the start and finish manhole, which ensure required access to the pipe. Thanks to this fact, the surface activities are disturbed minimally, compared to classical renewal methods. The swiftness of the renewal is also a big benefit. Particular sections can be finished in the interval of one or two weeks. Thanks to.

For access into the existing pipeline, a starting pit with a loading section is necessary. The piping is fitted in via pulling using a special winch (e.g. BAGELA) with an adjustable tractive force.

After monitoring with a camera, an assessment of technical state of the pipeline is performed. In cases where access to the pipeline is problematic, it is possible to demarcate a route of the pipeline including localization of the inaccessible or lost manholes and shafts using the RIDGID device and NaviTRACK Scout locator up to depths of 3.5 meters. Once access to the pipeline is secured, complete diagnostics can be performed. The results of the inspection are then included in a report with detailed topography of.
