Window sampling is carried out by either trailer mounted percussive samplers or hand held pneumatic samplers. Samples are recovered in seamless plastic tubes, for logging by a suitably qualified engineer.

Window sampling is suited to:-

  • Restricted access sites,
  • Contamination investigations,
  • Where disturbance must be kept to a minimum.

This method is used in geotechnical and environmental investigations and allows rapid recovery of a suitable volume of disturbed sample for chemical analysis for a range of common contaminants and for classification tests such as

  • Moisture content,
  • Plasticity indices
  • Grading in fine-grained soils.
