Geotechnical drilling is a type of drilling that is performed as part of the construction process. This is primarily for structures such as buildings and oil rigs, or as part of the investigation procedure carried out on site prior to construction.
Usually geotechnical drilling is used for site assessment. Site assessment is performed to determine if a site is going to be suitable for construction. This involves drilling to collect rock and soil samples, as well as drilling to establish soil stability and other matters of interest.
Unsafe rock or soil conditions could prompt a structural collapse, or cause a hazardous situation during an earthquake or flood
As part of the construction procedure, geotechnical drilling involves preparation for foundations, caissons, and various supports.
Geotechnical exploration is also performed in the search for banks of minerals, oil, gas, and other invaluable resources in the Earth. Drilling contractors would be required to take core samples and obtain information about the site. In this situation, geotechnical drilling might be completed by drilling contractors who specialise in scientific drilling applications, as opposed to drilling for construction.
