Different cutter head designs can be utilized based on geology. Soil samples are easily obtained by lowering and advancing a variety of different sized split spoon samplers through the hollow stem augers and out in front of the bit face.
This technology is ideal for drilling through unconsolidated alluvial deposits such as sands, silts and clays. The augers maintain bore hole integrity and facilitate soil sampling and well installation. It is the perfect application for environmental sampling because there are no additives, such as mud, used during the drilling process. Depth limitations will vary based on lithology. We have achieved depths to 450 feet using 3 ¼ inch ID augers.
