Geotech

Geotechnics is one of ARQ’s key areas of specialisation. ARQ Geotech is active in a wide range of geotechnical fields both within the borders of South Africa and internationally, providing professional engineering services to a wide range of clients in the private and public sector.

We undertake and oversee geotechnical investigations which range from basic to highly advanced – each, tailor made for site conditions, proposed land use and our clients need. We specialise in various forms of analyses and designs including Slope Stability & Seepage, Lateral Support, Piled and Shallow Foundation Design, Ground Improvement, and more. both within South Africa and internationally.

While hand-calculations and simple spreadsheet models are used to develop judgment in respect of geotechnical problems, our sophisticated analytical methods and software allow us to design ambitious and innovative geotechnical systems ensuring that our client receives the optimization allowed by the latest technological developments. Design-compliance field measurement is regularly applied to complete the investigation-analysis-design loop, or simply for the purpose of quality assurance, while the requirements of OHS and environmental legislation are rigorously observed to ensure safety and minimum disturbance to the environment.

Innovative and cost-saving solutions, coupled with detailed attention to each client’s specific needs, have established us as one of the preferred Geotechnical firms in the industry.

Dorstfontein Coal Mine East- Blasting and excavation of a new high-wall

Exxaro Resources is developing a new bord and pillar underground mine at its Dorstfontein Coal Mine East (DCME), 10 km north-east of the town of Kriel in Mpumalanga. The new underground mine will be accessed via seven portals driven from the base of the existing Pit 2 open cast operation. In order to ensure the safe operation of the new underground mine, the existing Pit 2 highwall was redesigned to a slope geometry appropriate to the projected 20-year life of the new underground mine. The collaborative services of Rockland Geoscience and ARQ Geotech were retained to design the highwall and monitor blasting and excavation works. An in-depth geotechnical investigation was undertaken …
