Geophysical Studies

Simply put, many times there are better ways to look 鈥渦nderground” than traditional drilling and sampling methods. Hitting 鈥渟urprises” during construction often stops projects and costs money. Therefore, minimizing the risk of encountering unforeseen conditions is a great benefit on any project. 港澳台图库 has the internal capability to do so utilizing geophysical testing techniques. This methodology allows for a more contiguous look at subsurface conditions than utilizing widely spaced borings, which is critical for identifying subsurface anomalies, including but not limited to solution cavities, voids, highly variable subsurface conditions, groundwater, underground seepage paths, geologic contacts and/or faults.

Geophysical evaluations rely upon the application of physical principles to study the Earth鈥檚 interior.聽Geophysical technologies are utilized to solve a wide range of geologic or geotechnical problems that come up with regard to environmental site assessment (ESA) or site development projects.

Some examples of geophysical project work conducted by 港澳台图库 include:

  • Subsurface detection of geologic strata (e.g., detection and delineation of changing soil or rock conditions, delineation of potentially expansive clay soils)
  • “Leaking Dam” investigations
  • Aquifer characterization (e.g., well siting studies, depth to groundwater determinations)
  • Fault/fracture delineation studies
  • Karst feature identification/delineation and mapping studies
  • Identification/delineation of subsurface manmade features (pipelines, buried cables, mining tunnels, etc.)
  • Resource assessment for aggregate quarry sites (e.g., rock and unconsolidated sediments)
  • Identification of preferential pathways for contaminant migration in the subsurface (e.g., buried gravel channels, fault zones, fill placement zones, etc.)
  • Identification and delineation of buried wastes (e.g., closed municipal solid waste landfills, dump sites, etc.)
