Total sounding

Total sounding (TS) is a sounding method performed as part of geotechnical investigation. The sounding combines conventional rotary-pressure sounding with bedrock drilling, including rotation, ramming and flushing modes. The result indicates sediment stratification, occasionally soil type and may verify depth to bedrock.[1]

History

The rotary-pressure sounding method was developed by the Norwegian Geotechnical Institute (NGI) and the Norwegian Public Roads Administration (NPRA) in 1967.[2]
