Specialist expertise

in the infrastructure sector

Our range of services in trenchless pipe installation includes the following:

• Displacement
  tunnelling Displacement tunnelling is most commonly used in pipeline construction in combination with open-cut methods for the installation of service connections. This method is particularly suitable for cohesive soils in the diameter range from DN 80 mm to DN 150 mm.
   
• Partial-cut
  tunnelling Partial-cut tunnelling is used in pipeline construction for the installation of road, rail and waterway crossings. Depending on the length and diameter of the application, we use different drilling rigs. These vary in size, weight and power. The smaller drilling rigs can be operated manually – thus allowing tunnelling from basements or shafts.
   
• Partial-cut tunnelling with pilot boring
  Partial-cut tunnelling with pilot boring is used in pipeline construction for the construction of road, rail and waterway crossings when greater accuracy is required. This method is only possible in soils that can be displaced. The system axis (pilot rod) is surveyed either using a theodolite, a laser or transmitter-receiver technology. Depending on the length and diameter of the application, we use different drilling rigs, which vary in size, weight and power. Smaller rigs can be operated manually and also allow for drilling from basements or shafts.
   
• Pipe bursting
  The pipe bursting method is a cost-effective, modern construction technique for the vibration-free, trenchless replacement or renewal of pipes made of metallic or brittle-breaking materials such as steel, grey cast iron, PVC or fibre cement. This method also offers the possibility of increasing the pipe diameter compared to the existing pipeline.

As a long-standing member as well as board member of the Austrian Association for Trenchless Pipeline Construction (ÖGL), WIBEBA is also committed to adhering to the ÖGL Code of Conduct and maintaining high-quality service standards.
