Contaminated sites and landfills pose special challenges for drilling. This applies regardless of whether a remediation has already been mandated by authorities or whether the extent of contamination only becomes apparent during the investigation. It is precisely during this phase that the quality of the sampling determines what will later be legally and technically usable.

STUBORE® operates without flushing fluids and with continuous casing. This prevents material fallout, displacement, and carryover by design—not through post-correction, but through the process itself. Targeted air cooling keeps the temperature low during the drilling process, which is particularly crucial for volatile contaminants such as CHCs and mobilizable trace substances like PFAS.

Each layer is extracted separately and can be analyzed separately. This is done with precise depth control, without loss of material and without cross-contamination. This creates documentation that authorities, experts, and property owners alike can use as a basis: for assessing the need for remediation, for liability issues, and for planning further measures.

Advantage of STUBORE®: Layer-specific sampling with minimal material displacement—reliable as a basis for decision-making in contaminated site and landfill investigations.
