Geophysical Survey

We believe geophysical techniques to be the perfect complement to site investigation and geotechnical testing and we have extensive experience in applying state-of-the-art non-invasive ground characterization techniques to all areas of geotechnical, civil engineering, mineral and gem and ground water industries.

Our area of expertise includes:

Site Investigation

  • Assist in determining depth of bedrock and water table
  • Locating fault and fracture zones
  • Measuring thickness of Soil, Rock and Fill layering
  • Environmental Science

    • Locating buried tanks and waste drums
    • Identifying & mapping ancient landfill sites
    • Sourcing leachate and contaminant plumes

    Water Engineering

    • Lake bottom profiling
    • Assessing defects in barrages, locks, dams and weirs
    • Measuring thickness of underwater foundations

    Mineral And Gem Exploration

    • Profiling bedrock depth and topography
    • Defining Alluvial Channels and Palaeo Channels
    • Locating Veins and other mineralized structures

    Groundwater Exploration

    • Detection of aquifer

    Ground Penetration Radar

    Ground Penetration Radar (GPR) utilizes pulsed high frequency radio waves to probe the subsurface without disturbing the ground. The GPR data are collected continuously as the instrument is towed over the ground surface and provides a real-time graphic image of the subsurface.

    Seismic & Resistivity Survey

    Seismic and Resistivity surveys are useful non-invasive, non-destructive tools that can investigate geological structure and rock properties. Seismic methods can rapidly characterize a site and determine elastic properties of soil and rock for geotechnical purposes, or estimate material density of the soil layers.

    Electrical properties are among the most useful geophysical parameters in characterizing Earth materials. Variations in electrical resistivity typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability.

    We also offer the following related services:

    • Seismic Reflection
    • Seismic Refraction
    • Seismic Surface Wave Measurement
    • Electrical Resistivity Imaging
