ESP’s geophysical services are proven to help solve problems and add value to environmental and engineering projects. The goals of our geophysical studies are to reduce risk and lower design and construction costs.
Example Geophysical Services:
- Locating underground storage tanks (USTs)
- Collecting surface wave seismic data for IBC site class
- Delineating buried waste such as municipal landfills
- Exploring the extent of sinkholes and karst features
- Mapping dam seepage paths
- Locating voids
- Mapping lake sediment thickness
- Locating steel reinforcement and PT cables
- Evaluating groundwater-bearing fractures and aquifers
- Mapping depth to bedrock
Typical Geophysical Methods:
- Ground-Penetrating Radar (GPR)
- Electromagnetic induction (EM)
- Seismic refraction
- Surface wave seismic (MASW)
- Seismic reflection
- Electrical Resistivity Imaging (ERI)
- Induced Potential (IP)
- Self-Potential (SP)
- Micro-gravity
- Magnetometer and gradiometer
- Borehole geophysics
- Overwater/underwater geophysics
