What is the primary purpose of a geotechnical boring?

The primary purpose of a geotechnical boring is to create a hole for sampling, measuring, or testing the various strata of soil and rock beneath the surface. This process is essential in geotechnical engineering, as it provides vital information about the subsurface conditions, such as soil type, composition, density, and moisture content. Engineers use this data to evaluate the site's suitability for construction projects, including the design of foundations and other structures.

Sampling and testing the strata help in understanding the behavior of soil under different conditions, which is crucial for ensuring stability and safety in construction. This approach allows engineers to make informed decisions based on empirical data rather than assumptions, ultimately leading to better engineering practices and safer construction outcomes.
