Geotechnical Drilling

Geotechnical Drilling — ABC Liovin Drilling

Geotechnical Drilling is used to investigate the stability, classification, and change of soil type as a function of depth and location. It can also be used to define groundwater depth, movement and location and its impact on the soil. Drilling, soil sampling, and in-situ instrumentation are all used to provide data for engineering and design prior to construction. This data is then used to

Core Sampling in Geotechnical Drilling Fordia

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
