Sonic Drilling – Sonic drilling is a safe, clean and low-impact drilling technique. Boreholes are drilled, cored and cased by rotating and vibrating the rod, core barrel and casing at resonant sonic frequencies. Sonic drilling generates considerably less drill spoils than auger, mud or air rotary methods, saving additional project resources.

When drilling with augers, you usually do not need a lot of water. As a result, and to reduce costs, the types of pumps used in geotechnical drilling are sometimes not as high performance. When geotechnical drillers need to do core sampling, the water pump must have a high enough pressure to flush out cuttings and cool the bit.
