Our extensive experience of jacked structures  includes more than thirty traffic underpass structures based on modular jacked abutments and foundations, twenty  based on jacked boxes  and some twenty pedestrian subways.  In addition our jacked projects have included a number of culverts and cable ducts as well as the installation of  sewers, water lines  and other utilities using jacking and micro-tunneling techniques .

The majority of the work has been under rail tracks and roads but also under buildings and environmentally sensitive areas where surface disruption has to be avoided.

Work has been undertaken in  a number of countries including UK, USA, Australia, Canada, South Africa, India, Indonesia, Malaysia and Singapore.
