Geotechnical investigations or ground testing is carried out to determine the characteristics of the site. These investigations provide valuable data that are used to evaluate and interpret the ground conditions and ultimately inform structural design, manage risk, and provide recommendations on appropriate excavation and construction methodology.
Ground testing can also be valuable where existing construction is damaged due to ground related issues such as settlement or subsidence, ground water etc. In these cases, an accurate determination of existing conditions, such as compaction of soils/clays, presence of water, or depth to bedrock can be crucial to design of appropriate remedial works.
As it is impossible to see below the surface, it is necessary to use equipment that can help us interpret the subterranean conditions of your site. In most cases, testing is comprised of bore holes, utilising hand operated augers or mechanical core drilling, where coring through rock is required, and penetrometer testing. The combination of these test methods allows an inferred geotechnical model to be developed for your site.
