Mining and extraction specialists


Maiden Geotechnics is one of the oldest geotechnical engineering firms in South East Queensland, Australia. The company has grown from the provision of basic soil testing services for residential houses to a major geotechnical and environmental engineering consultants and ground water technologists. Our services include but not limited to the following:

  • Site Investigations for major and minor projects
  • Contamination site assessments
  • Testing and preparation of management plan for acid sulphate soils.
  • Bulk earthworks testing, coordination and management.
  • Pavement analysis and design
  • Laboratory testing services, and Contract drilling services

Up to now, our operations had extended throughout Queensland, NSW and the Northern territory of Australia. As from next year, we hope to be fully established in Ghana, providing services in geotechnical engineering, environmental services, water-quality testing and groundwater explorations. Our previous projects have included geotechnical

investigations for:

  • Residential, Industrial and Commercial Buildings.
  • Bridges and Car Parks
  • Multi-storey constructions
  • Slope stability investigations
  • Investigations into distressed properties
  • Old and New Roads Pavement investigations
  • Supervision of piles and bored pier foundations
  • Investigation for and Design of retaining structures
  • Contaminated site assessments


Drilling Crew The company currently operates three drilling rigs. We also stocks simply testing equipments, such as hand augers and dynamic cone penetrometer tests equipments for investigations at areas with difficult access conditions.
