M&W Drilling operates a fleet of 18 track-mounted rigs with hollow stem auger capability, giving us the capacity and flexibility to mobilize quickly. Our drillers are cross-trained on hollow stem auger equipment, allowing us to shift crews as needed and respond to urgent requests.
Hollow stem auger drilling is a soil drilling method that uses continuous flight augers with a hollow center. As the augers advance into the ground, they create a stable borehole. Sampling tools, SPT equipment, or well materials are lowered through the hollow center without removing the augers, helping maintain borehole integrity in loose or unconsolidated soils.
Hollow stem auger drilling is best used for shallow environmental and geotechnical investigations, including soil borings, groundwater monitoring well installation, and Standard Penetration Testing (SPT).
Hollow stem auger drilling is fast, efficient, and cost-effective for shallow soil investigations. It requires no drilling fluids, reduces site disturbance, and allows for continuous sampling and well installation. It is particularly effective in soft, unconsolidated formations where borehole stability is critical.
Yes. M&W Drilling operates 18 rigs with auger capabilities, of which many are designed for tight-access, urban, and sensitive job sites. Our equipment performs well near structures, within confined spaces, and on soft ground where larger truck-mounted rigs cannot operate safely or efficiently.
Yes. M&W Drilling can perform indoor hollow stem auger drilling and control equipment exhaust using catalytic converters or exhaust extension tubing. This allows drilling operations inside buildings, warehouses, and industrial facilities while maintaining a controlled and compliant work environment.
