Horizontal auger boring

Horizontal auger boring – Ideal installation method especially in soft soil types

Horizontal auger boring (HAB) is at its best when you want to drill under roads or railways big steel-, concrete-, plastic composite pipes or other applicable pipe materials. The method is widely used internationally. This method is best applicable with pipe diameters over 1000mm and drilling distances 30-120 meters.

Good planning leeds to best results

When planning infrastructures, it is very important to start cooperation at the earliest possible stage. Then we can efficiently plan and decide what is the best and most cost-effective solution to meet customer’s needs. Especially if the soil is sand or clay and large penetrations are required, horizontal auger boring is one of the best methods. Infra designers and engineers should be contacted already at the planning stage in order to find the best solution for the project.

Best application and selection criteria

uger boring it is possible to solve situations where big pipes need to be penetrated to sand-, silt- or clay soil. The method is most useful in sewage and rainwater drains, pressure drains, drums, water pipes and gas pipes. The material used in those pipes is protective steel casing pipe. Problematic materials for horizontal auger boring are moraine, rock and blast stones.

  • Installation of steel casing pipes
    – sewage and rainwater drains
    – pressure drains
    – drums
    – water pipes
    – gas pipes
  • A very cost effective and quickly installable method in large pipes with over 1000mm in diameter.
  • Can be used in many different soil types, ideal in solid sand- and clay.
  • The installation conditions of the target (soil) must be carefully investigated before deciding to use horizontal auger boring
  • Diameters from 800mm up to 2500mm
  • Most typical boring lengths vary between 30-120 meters
  • Suitable soil: clay, silt and sand
  • Problematic soil: blast stones, moraine and rock
