The hydros®technology has been developed by Karl Weiss for trenchless replacement and new laying of both services and mains. In the hydros®technology, hydraulic pulling units remove the old cast iron pipes from the ground. The new pipe is then attached to the old pipe via a transitional adapter so that the new pipe is laid into the soil while the old pipe is being removed. The benefits of this extremely quiet (< 55 dB (A)) and vibration-free technology is fast, cost-effective, environmentally friendly and complete replacement of pipelines made of any material. The following techniques are available:
For services:
For mains:
hydros®PLUS: content
hydros®PLUS pulling rod
Connection between old pipe and new pipe via transitional adapter
Cracking open the old pipe via splitting cone
