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.

Directional core drilling has found its specific niche, not by no reason. The method can provide certain information that may not be easily available through other methods of geotechnical investigation. For one, directional core drilling can provide continuous core sample and geological information from the planned tunnel trajectory.

The two most common methods of drilling for soil samples are the wet rotary method and the hollow stem auger. The objective in sampling a soil or rock deposit is to obtain samples that have the least amount of disturbance. The level of the groundwater at a site is a very important piece of information for any geotechnical investigation.
