Area limiting excavation control system for construction

About Pipe Jacking

A range of mechanical and remote control excavation systems are available. Pipes in the range 150mm to 3000mm, can be installed by employing the appropriate system. Construction tolerances are comparable with other tunnelling methods, and the pipe jacking method generally requires less overbreak than alternative systems.
