Karl Weiss Technologies GmbH products

hydros BOY: replacement and new installation of connection pipelines. This technology is used for the trenchless, same-channel replacement and new installation of steel, grey cast iron or ductile cast iron gas and water connection pipelines. All available diameters can be replaced using grab jaws. The maximum exterior diameter should be 110 mm, and as a rule the maximum length of one section should be no longer than 25 m.

hydros LEAD: replacement of lead connection pipes. HydrosLEAD technology, also described as a wind-up process supported by internal pressure, is used for the trenchless replacement of lead or or flexible plastics mains connections, preferably by PE pipelines. As a rule, a pit is only required at the point where the house connection meets the mains, and if necessary a further pit in front of the basement wall.
