Our service is carried out directly from the manufacturer or by qualified and authorized dealers. You have direct access to the service hotline in the R & D department - the fastest way for service questions.

A good documentation, even with machines that have been in use for a very long time, ensures that we can continue to help you even years later.

For each machine we offer a service package that ensures a long lifetime of your machine.

You have effectively very low follow-up and repair costs per machine. High quality standards instead of expensive repair costs - that is our claim to trenchless technology.

Spareparts long-term service - high investment protection

We have a huge spare parts warehouse. Thanks to intelligent computer-aided control, essential spare parts are available immediately.

In many cases, we can still offer you service and spare parts for 20 years after delivery of your machine.

Within Europe, we usually deliver replacement parts on weekdays within 24 hours. A lean logistics and a fast process organization make this possible.

With each delivered machine you receive three complete spare parts catalogs (in print form and digital). In case of service, our team of experts can help you quickly and competently.
