Core Sampling in Geotechnical Drilling
In most geotechnical and environmental drilling, augers are used to drill in the majority of projects. However, the need still arises to perform core sampling for certain geotechnical projects, usually when the presence of bedrock needs to be confirmed. An auger or split spoon will not be able to enter the bedrock so drillers have to use core sampling methods to be able to penetrate and obtain a core sample.
