What is Geotechnical Drilling?

Geotechnical drilling is a specialised site investigation technique designed to collect soil, rock and groundwater samples for the purpose of assessing their physical properties. 

This information is then used to evaluate the suitability of a site for mining and construction. It can also help to determine the constitution of geological structures and climate history for scientific purposes, as well as mitigating potential geotechnical hazards. 

Geotechnical drilling – also known as ‘geotechnical boring ‘ – is usually undertaken by specialist drilling contractors, who operate under the supervision of a geotechnical engineer. 

What Equipment is Used in Geotechnical Drilling?

This form of drilling involves the use of specialist geotechnical drilling equipment that can vary in size and capabilities and will depend upon the specific requirements of the project. 

Geotechnical drill rigs are innovative mechanical and hydraulic systems that are used to create holes in the ground. They range from enormous structures that house equipment used to drill oil wells, to small rigs (called ‘augers’) that can be moved manually by one person.

Small drill rigs are often mobile and can be mounted on a truck, track, or trailer, while the larger drill rigs – such as those used in offshore oil rigs – are more permanent structures.

Why Use Geotechnical Drilling?

Geotechnical borehole drilling is generally carried out as part of the site analysis process prior to mining or construction. 

It forms a crucial component of civil engineering, mining, construction, and environmental projects, as it provides valuable information about the subsurface conditions that cannot be obtained through surface observations alone. 

This information is critical in ensuring the safety and longevity of structures built on a specific site. Unsafe rock or soil conditions can pose an enormous safety risk and, in extreme cases, could even trigger a structural collapse.

By law, a site analysis is required before a building permit can be granted, to identify any issues that could pose a risk to the development. 

In the mining industry, geotechnical drilling not only plays a critical role in enabling mining companies to make informed decisions regarding the design, construction, and operation of mining infrastructure, but also provides vital information in the search for deposits of minerals, oil, gas, and other valuable resources. 

Furthermore, geotechnical core drilling may also be used by scientific researchers who wish to acquire samples, such as ice cores, to provide an insight into the earth’s physical make-up – including the constitution of ice sheets or geological structures – and climate history. 

What is Involved in Geotechnical Drilling?

Geotechnical core drilling forms a key component of the preparation for foundations, caissons, and various supports for mining, construction, and environmental projects.

It also plays a fundamental role in identifying oil, gas, and mineral deposits – thereby determining the feasibility of a site for mining purposes, and/or providing useful data for scientific research.

Professional geotechnical drilling contractors will use specialist geotechnical drilling equipment (such as drill rigs) to drill boreholes into the ground, to collect rock, soil and groundwater samples from various depths and angles.

The samples are collected using hollow drill bits that extract the samples and then bring them back up to the surface. 

The advanced technology utilised by these innovative geotechnical drilling machines allows for exceptional levels of accuracy in terms of sampling – along with minimal impact on the surrounding environment. 

Sampling methods include standard and cone penetration testing, shear vane testing, trial pits and more.

These samples are then carefully analysed in a laboratory to establish their physical properties, such as density, shear strength, and permeability – and, in turn, determine the integrity of the site.
