GeoServ performs geotechnical drilling using an automatic drop hammer mounted on our 6620DT ATV track-mounted drill rig. We can collect Standard Penetration Test (SPT) blow counts in accordance with ASTM Standards D1586-99. This can be performed with augers or a zero-cutting method using soil-probing rods as the outer casing. This system offers consistent and accurate SPT results. This is an exceptionally clean and efficient method for completing geotechnical projects. In addition, with a small foot print and minimal overhead clearance, this rig is ideal for projects where access is limited.
