We cover all tunnel diameters with our extensive fleet of tunnel machines.
With 20 years of trenchless construction experience since 1999, we have used microtunnelling techniques to succesfully construct tunnels for pipeline infrastructure beneath major roads, railways, waterways and environmentally sensitive areas.
We typically use two specific techniques to undertake trenchless construction—slurry pressure balanced micro-tunnelling and pilot auger soil displacement. Either is used to address access challenges, site footprints, ground conditions, minimise urban disruption, or to efficiently cover large distances. Both techniques are used to construct
critical drainage, water or energy utilities infrastucture.
Rob Carr owns a fleet of 34 micro-tunnelling machines up to diameters of 2200mm OD covering all ground conditions. The machines are supported with wide ranging ancillary items in the form of control cabins, jacking frames, slurry separation, gantries, power generation and guidance equipment. We typically use Iseki Unclemole and Unclemole Super machines, which have a reputation for versatility, efficiency and environmental sustainability.
