Microtunnelling

When precision is required – our unique technology delivers results.

Bothar provides superior microtunnelling solutions using Bothar Built Fully Steerable Device (FSD) Microtunnelling machines as well as equipment manufactured by world-leader Herrenknecht to complete trenchless installation of pipelines. Our solution uses a remotely-controlled, guided operation that provides continuous support to the excavation face by applying mechanical or fluid pressure to balance groundwater and earth pressures. This slurry-supported excavation process and comprehensive range of AVN systems with specialized cutting heads make it possible to tunnel in all types of ground conditions ranging from slit to clay to incohesive soils, and further to gravel and hard rock.

Microtunnelling advantages

  • Cost effective drilling method

  • Slurry-supported and adaptive process

  • Significantly reduced environmental impact compared to traditional methods
