GEOTECHNICAL INVESTIGATION

  1. Drilling for Geotechnical Subsurface Investigation
    GEOTECHNICAL SOILS INVESTIGATIONS
    Drilling for geotechnical subsurface investigations including this project to install an array of geothermal heat exchanger boreholes that store thermal energy collected in subsurface soils.
  2. Fault Study
    FAULT INVESTIGATION
    When a site is located within the City of San Diego's Special Studies Zone for potentially active faulting, a fault trench study is required. HGI has experience in providing fault trench logging and studies.
  3. Registered Geologist
    CERTIFIED ENGINEERING GEOLOGISTS
    Geologist characterizing and classifying on-site soils.
  4. Subsurface Investigation
    SOILS EVALUATION AND MITIGATION
    Subsurface investigation using test pits to characterize soils on-site.
  5. Geotechnical Investigation for Commercial Development
    INVESTIGATIONS FOR COMMERCIAL DEVELOPMENT
    Geotechnical investigation and construction observation for commercial development including warehouses, retail facilities and office buildings.
  6. Recommendations for Pavement Design
    RECOMMENDATIONS FOR PARKING LOTS AND PAVING
    Soil investigation, construction observation and testing of parking lots and associated paving.
