Project Status/Year Completed: 2016


Location: Vosloorus, Gauteng, South Africa


Project Area: 2.15ha


Project Type: Township Development on dolomite


Job Description/Scope of Work: To provide a footprint-level dolomite risk assessment and to determine the nature, distribution of the soil and rock profile underlying the proposed structures.


No. of Test Positions:

Phase 1:

  • Gravity survey of the entire area,
  • 4 rotary-percussion boreholes drilled 6m into the bedrock, and
  • 7 shallow test pits excavated by TLB.

Phase 2:

  • 7 additional rotary-percussion boreholes for a more detailed investigation for the Council for Geoscience.

Soil Tests Performed: Grading and Atterburg Limits, Natural Moisture Content, One-dimensional Consolidometer, CBR.


Goal of Investigation: To perform a dolomite risk assessment and near surface geotechnical investigation in a dolomite region that adheres to the standards of the Council for Geoscience in order for development to take place.
