Geotechnical Drilling

Geotechnical Drilling

Geotechnical drilling is a critical part of investigating a site before construction begins.  South Western Drilling’s qualified driller’s undertake the task using specialised drilling equipment.

We work with you to establish the specific requirements of the project to determine the type of equipment to be used.  Drilling rigs of different sizes and capabilities are used depending on the project;  small – moved manually by one person, large mounted on a trailer or track, or an off-shore semi-permanent structure.

Before building permits are granted, the law requires safety investigations of the site. Continuous safety monitoring is also required to detect changes or developing problems that could pose a risk.  South Western Drilling works with a team of highly experienced professionals that undergo continuous training to meet and exceed customer expectations.

Geotechnical drilling is normally done to analyse whether the site is appropriate for upcoming construction. The soil’s stability and other matters of interest can be analysed during the drilling process. Soil and rock samples are also taken for testing, to determine the possibility of hazardous scenarios during floods or earthquakes or structural collapse.
