Its borehole division provides water wells, water abstraction boreholes and larger open boreholes.

The company also offers borehole closure and decommissioning through pressure grouting or over-drilling and pressure grouting.

Ground investigation capabilities include dynamic sampling, conventional and wireline rotary coring, open-hole drilling, monitoring-well installation, geotechnical testing and work on potentially contaminated sites.
