Who We Are

  • Engineering & Infrastructure – site classification, soil profiling, Vs30 studies and foundation analysis
  • Environmental & Groundwater – subsurface mapping, contamination assessment, aquifer studies
  • Exploration & Mining – Electrical resistivity imaging, fault mapping, and mineral exploration
  • Geohazards & Seismic Risk – Seismic hazard assessments, site response analysis, earthquake zonation
  • Saltworks & Coastal Projects – Subsurface salinity profiling and shallow marine geophysics for solar salt pans

GGC combines advanced field technologies with expert interpretation to ensure every project yields reliable, actionable subsurface insights. We use:

  • MASW (Multichannel Analysis of Surface Waves)
  • Seismic Refraction & Downhole/Crosshole Testing
  • Ground Penetrating Radar (GPR)
  • Electrical Resistivity Tomography (ERT)
  • Potential Field Methods (Gravity & Magnetics))
  • Integrated Geotechnical & Geological Correlation

We work closely with engineers, planners, and developers to meet both technical and regulatory requirements, always prioritizing safety, sustainability, and cost-efficiency.
