Continuously cased boreholes, for layer-specific samples without material loss or cross-contamination.

Stable borehole conditions, for precise groundwater measurements and reproducible measurement results.

Complete stratigraphic sequence, sampled at the correct depth, as a solid basis for every geotechnical assessment.

Material carryover and cross-contamination are prevented by design, not corrected afterward.

Slopes, narrow inner courtyards, active railway lines, STUBORE® drills where other methods have to give up.

Stable, documented borehole conditions, for measurement results that stand up in planning and expert reports.

Piezometers, inclinometers, gas wells, precisely installed under the protection of continuous casing.
