Drilling Services: Auger Drilling

Auger drilling or boring is a conventional drilling system where holes are created by a rotating chiselled drill bit. Auger drilling rigs are very effective for overburden soil above rock formations and mineral deposits. This technique is commonly used for environmental and geotechnical sampling, as well as for construction and mining applications. Aardvark uses both types of auger drilling rigs:

Solid Stem Augers are used primarily for geotechnical drilling in consolidated soils. They are effective in soft to medium formations and are a great tool for creating small diameter boreholes without introducing any fluids. Solid augering is not effective in formations prone to collapse.

Hollow Stem Augers (2 3/4”, 4 1/4”, 6 1/4”, 10 1/4”) are used for unconsolidated soils, wet conditions and monitoring well installations. These are used when formations are prone to collapse. Hollow stem augers tend to be of a larger diameter, making for a slower process and greater amount of spoiler.
