SLURRY MICROTUNNELLING

Slurry microtunnelling is classed as “non man entry” boring using laser guidance for accuracy and steering. Tunnelcorps machines can drill in varying ground conditions from very soft formations to hard rock and is used for high accuracy, fine grade gravity sewers, stormwater systems, and water, oil and gas pipelines. Tunnelcorp also installs steel casing pipe allowing the installation of HDPE, PVC and other non-jacking carrier pipes. Tunnelcorp operates four laser guided microtunnelling machines utilising various forms of spoil extraction and face control. Tunnelcorp uses both slurry extraction and vacuum extraction microtunnellers providing us with the capability to operate in most types of ground conditions and below the water table.
