SONNTAG operates a workshop specialized in pipe jacking at its headquarters in Dörth. Our qualified employees maintain all our equipment and further develop the machines.
SONNTAG's customers benefit from our exceptionally comprehensive technical service:
- The jacking machines are transported to our workshop in Dörth for inspection during each implementation between the target and starting excavation pits. This reduces the risk of machine-related construction delays.
- We can react without delay when changing geological conditions require a conversion of the excavation tools of the jacking machines. This saves valuable construction time.
- We can individually develop and build the necessary jacking machine for each application area from an economic perspective. This optimizes costs for the client.
Since 2007, our operational jacking systems have carried the CE mark. The machines thus meet all EU directives for minimum requirements for technical safety as well as for health, environmental, and consumer protection.
