Our experience


Posted on 14 March, 2019



Engineers have the last say on where geotechnical drilling is performed. Everything is monitored by a professional to confirm the placement of the drilling activities and ensure that everything is being carried out correctly. If something in the drilling process is not adequately performed, it can cause issues to arise in any planning and construction of projects and thus could cause delays or failures. That’s why it’s very important that all geotechnical drilling is undertaken by drilling contractors who are qualified to operate specialised drilling equipment and have a clear understanding of underground strata.

Drilling locations

Geotechnical drilling rigs are the machines that are used to create holes in the ground for facilitate soil sampling and soil testing. These holes can range from the surface to hundreds of metres deep depending on the engineer’s requirements. These extracted soil and rock core samples are then sent to laboratories to be analysed. Mobile geotechnical drilling rigs can be mounted on trucks, on steel or rubber tracks or even on trailers.

What is geotechnical drilling?

Soil conditions or unsafe rock can lead to structural collapse, or it could create a hazard when an earthquake or flood takes place. To retrieve this information involves drilling a hole to collect soil and rock samples, as well as drilling to determine soil stability and other matters of interest. This task is usually under the supervision of a geotechnical engineer who oversees the drilling process to ensure that it meets the requirements of the project. In Australia, regulations require a site to be investigated for safety before a building permit can be granted. The data collected is used to determine whether or not a site is appropriate for the planned construction.

Geotechnical drilling is a type of investigation drilling typically used for soil sampling and soil analysis. It is usually performed as part of the preplanning phase for a construction process.

The samples that are retrieved through this process are typically SPT hammer sampling and down hole Rock Core sampling, these samples assist engineers in establishing what will be required in the construction of structures such as Bridges, Highrise Buildings, Tunnels, Pipelines and Roads to name a few. Site analysis is performed to establish whether or not a site is going to be appropriate for construction proposed and what engineering will be required to make the structure safe.
