GEROfit® NEXUSPermanently locatable.
GEROfit® NEXUS can be permanently and actively located with commercially available locating devices. The protective jacket pipe can be used for all installation methods, avoids life-shortening damage to the core pipe and retains the full operational safety coefficient. See for yourself with our explanatory video!

Wire connectors in different lengths for connecting the integrated locating wire system in the welding area.
Highly tear-resistant GEROfit® sealing tape for a watertight reprotection of welded joints and exposed pipe surfaces.
Scratch-resistant fabric tape for reprotection of the welding area. Easy handling thanks to subsequent curing. High flexibility when the pipe is bent.
When laying in a sand bed, the excavated material must be replaced with a sand bedding in accordance with DIN EN 805. Restrictions on the grain sizes of the bedding material must be observed.
Without sand bedding
Due to the verification by an independent testing institute, the installation is possible without a sand bed. This eliminates the additional expense of replacing the excavation with a sand bedding in accordance with DIN EN 805 (transport, landfill).
In the ploughing method, the soil is displaced by a plough blade and the pipeline is placed on the bottom of the soil.
In the milling process, a pipe trench is cut into the subsoil by machine and the pipeline is laid on the bottom of the trench.
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.
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.
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.
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.
Pressure pipe with protective jacket for trenchless installation methods, additional protective functions such as notch/scratch and crack resistance, easy and time-saving processing.
