In-Tunnel Drilling & Probing

In-Tunnel Drilling & Probing

WJ are the leading UK contractor for the installation of in-tunnel dewatering systems and investigative probing surveys.

Our fleet of articulated, restricted access rigs are capable of installing both in-tunnel wells and probe holes axially, radially and at a range of inclinations, ahead of tunnels, cross passages and shaft construction.

Dependent upon ground conditions and project requirements our rigs are capable of drilling distances of up to 20m, with a stuffing box or blow-out preventer used to reduce the risk of ground loss during the drilling process.

Where required it can be possible for probe bores to be constructed as either wellpoints or ejector wells to allow immediate pore pressure control and enable excavation to continue.
