Geotechnical Engineering - Geotechnical Investigations
Jones & Wagener provides comprehensive site investigations for all types of developments in all key industries. These include large industrial, power generation and mining projects, commercial developments, and transportation routes. We also investigate greenfields and brownfields sites for the purposes of environmental impact assessment and rehabilitation design.
We are experienced in all the standard exploration and testing techniques such as rotary core and percussion drilling, penetrometer testing, plate load tests, pressuremeter and Goodman jack testing, pumping tests and geophysical surveying. We have also devised innovative testing procedures to suit particular requirements such as testing trial piles and full scale settlement and heave tests.
Site investigations are planned and designed according to the SAICE Code of Practice for Site Investigations and with consideration of the risk to humans, property and to the environment.
