CPT Advantages

Detailed hydrogeologic profiling at an average rate of 400 to 500 feet per day
Provides a near continuous log of the site lithology
Real-time data enabling an accurate, on-site, lithologic subsurface representation
Ideal for sands, silts, clays, soft soils and mine tailings
Provides piezometric data in addition to geotechnical design parameters
Add-ons such as seismic, resistivity, UVIF and gamma modules provide additional data
