Trenchless installation technology is increasingly in the spotlight. It often saves time and money compared with conventional open trench construction. Sometimes local conditions do not allow any other option.
Whatever the reason for your decision in favor of trenchless installation technology, Gerodur offers you suitable system components. Even far from the standard, we will work with you to develop modified and individual solutions.

Trenchless installation methods

Pipe bursting
Static pipe bursting is the renewal of the old pipeline along the same of the old pipe route, which is shattered by the bursting head and the remaining fragments are pressed into the surrounding soil.![Gerodur Horizontal Directional Drilling (HDD) computer graphics]()
Horizontal Directional Drilling (HDD)
The new installation by HDD is usually carried out in three successive work steps. With the continuous pilot borehole, which is controlled by positioning the route is determined. This is followed by the widening of the borehole and the pulling in of the pipe string.![Gerodur relining installation computer graphics]()
Relining
In the case of relining with annular space, the new pipe string with a smaller cross-section is pulled into the cleaned old pipeline using a pull-in device.![Gerodur soil displacement method computer graphics]()
Soil displacement method
In the soil displacement method, a pneumatically operated displacement hammer, a so-called "rocket", is used to excavate an underground cavity. The new pipeline is then pulled into it.
