Microtunneling is currently the most accurate pipeline installation method available to the civil construction industry. Line and grade tolerances of +/- 25mm are the microtunneling industry standard. UEA specialises in Pilot Tube Microtunneling using a Laser Guided Boring Machine (GBM).

Pilot Tube Microtunneling

UEA operates its pilot tube microtunneling system in conjunction with an auger boring system. Once the pilot bore has been completed a steel case is augered into place into which the carrier pipe can be intalled. The system is most suitable for installing casing pipes in soft displaceable ground conditions. Subject to ground conditions and bore lengths casing diameters of up to 1500mm can be installed.

Installation diameter and distances can vary based on ground conditions.
