Steel pipe jacking
Load-bearing casing, no settlement.
From the launch pit a hydraulic machine jacks the steel pipe section by section under the road or track. An auger inside the pipe removes the soil and carries it back to the pit.
How we work
Section by section, under live traffic.

The right choice for straight, large-diameter, load-bearing crossings.
At road and rail crossings traffic keeps moving, and there is no later settlement under the pavement or track.
