Physical Soil and Rock Properties

Seismic methods are ideal for obtaining continuous Shear-wave (Vs) and Compressional-wave (Vp)

Data collected from Surface


Data collected in a Borehole

Downhole Testing and Results as per ASTM D

Crosshole Testing and Results

Downhole Testing

Geophysical Surveys obtain the Shear-wave velocity (Vs) and the compressional wave velocity (Vp). With these two values all moduli can be calculated easily.
