  • Archaeological Services

    Archaeological Services

    The use of geophysics has become increasingly beneficial to archaeological surveys. A geophysical survey should not be used to replace an in-depth archeological survey conducted by a qualified professional archaeologist. Instead, it should be used as one of many tools that can be applied to the investigation. Geophysics can be used to provide either a general site overview or a higher resolution image of a particular area of interest. This data helps...

  • Infrastructure Studies Services

    Infrastructure Studies Services

    Geophysics is an important forensic tool in a wide range of infrastructure related studies. The non-destructive tests (NDT) enable the engineer or geophysicist to inspect the interior of a structure without the need to physically dig, drill or otherwise destroy part of the structure. GeoView has performed thousands of infrastructure related studies for both governmental agencies and private contractors throughout the United States and the Caribbean.

  • Residential/Commercial Sinkhole Studies Services

    Residential/Commercial Sinkhole Studies Services

    The investigation of potential karst (sinkhole) activity at residential or commercial properties or undeveloped land is a multi-disciplinary process in which geophysics plays a critical role. Subsurface geology in karst environments is very complex and is often masked at the surface. Properly selected and applied geophysical tools will provide a 2 or 3 dimensional perspective of subsurface geological conditions in these settings.

  • Utility Designation Services

    Utility Designation Services

    The American Society of Civil Engineers (ASCE) has developed a standard of care guideline, which describes four quality levels of utility depiction.

  • Marine Based Services

  • Scanning Beneath the Seafloor Services

    Scanning Beneath the Seafloor Services

    GeoView employs three methods for studying the geologic strata and objects buried beneath the seafloor. These include Sub-bottom profiling, Marine Seismic Refraction and Marine Seismic Reflection. GeoView owns and operates an Edgetech sub-bottom profiler. It generates a swept frequency source to produce a high resolution image of the sub-bottom at penetration depths up to 50 meters. It is useful for mapping sediment thickness, karst surveys,...

  • Sediment Thickness Studies Services

    Sediment thickness studies are typically performed to: Identify and quantify offshore borrow pits, Survey sediment with channels, Pre/Post dredging surveys, Port expansions, Pipeline studies, Sand wave and Scour/Erosion Surveys.

  • Land Based Methods

  • Electrical Resistivity Measurements

    Electrical Resistivity Measurements

    Electrical Resistivity measurements are performed by placing multiple electrodes in contact with the soil or rock. Current is transmitted and received between pars of the electrodes. The surveys can be performed as traditional, single Vertical Electrical Soundings or with multi-channel systems to produce continuous resistivity cross-sections of the subsurface. The depth of investigation and survey resolution is dependent upon the spacing between...

  • Electromagnetic Methods

    Electromagnetic Methods

    Electromagnetics uses inductive techniques to measure conductivity of the subsurface without the need of electrodes or ground contact. The methods include frequency domain electromagnetics (Geonics EM-31, EM-34, EM-38 and GSSI Profiler), time domain electromagnetics (Geonics EM-61, Geonics PROTEM systems and White handheld systems), and VLF systems. Depending on the target, the depth of investigation can range from a few meters to several hundred...

  • Electronic Utility Locating Services

    Electronic Utility Locating Services

    Conventional Pipe and Cable locators are an important tool used in most utility designation studies. The locators can be used in either a passive or active mode. The most common use for the passive mode is to find cables and conduits carrying live power (50-60 Hz) and communication cables (29-33Hz) signals. In the active mode, a current is transmitted or broadcast into a metal pipe or conduit and the path of the pipe/conduit is identified by following...

  • Impact Echo Method

    Impact Echo Method

    The Impact Echo Method is used to determine the thickness of concrete, wood, stone, and masonry structural members. It can also be used to determine the condition when voids, honeycombing and/or cracks are suspected. A solenoid is used to create a high frequency compressional wave that reflects off the bottom of the structure or from a flaw in the structure. The reflected wave is then recorded, processed and displayed. GeoView's Impact Echo Testing...

  • Pile Integrity Testing Services

    Pile Integrity Testing Services

    Pile Integrity Testing, also known as Sonic Echo Testing and low strain dynamic testing is used to determine the length and integrity of deep foundations and driven piles. The method works well in concrete or timber foundations that are not excessively slender. In order to perform the test, the top (preferably) or side of the foundation must be accessible. An accelerometer is placed on the top of the foundation and a lightweight hammer is used to...

  • Seismic Methods

    Seismic Methods

    All seismic methods measure the travel-time and frequency of elastic waves as they propagate through the subsurface. The methods commonly used in shallow geophysics involve using an impact source (hammer, weight drop, explosive source) to generate the seismic wave and recording the arrival of the waves with a seismograph and a series of geophones. The types of seismic methods are divided into broad categories on the basis of the geometry of the ray...

  • Thermal Imaging Services

    Thermal Imaging Services

    Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers) and produce images of that radiation which are called thermograms. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature to a range of 0.1o C. A thermal imaging camera is able to view and record these variations in temperature....

  • Vacuum Excavation Services

    Vacuum Excavation Services

    Vacuum excavation is a tool that is used to confirm, safely expose and examine underground utilities that have been identified using geophysical methods. An air “knife” is used to loosen the soil and a powerful suction hose is used to remove the soils overlying the utility. Once the target utility has been exposed, measurements can be made regarding the composition, diameter, depth and centerline of the utility. This information is often...

  • Bathymetric Profiling Services

    Bathymetric Profiling Services

    The basic principle behind bathymetry is the use of acoustic waves (in the range 30 to 250kHz) to measure the water depth. A complete bathymetry system includes a vessel, an echo-sounder (analogue or digital) and a positioning system (DGPS or RTK). The depth information is geo-referenced in real time and recorded on a portable computer on-board the boat.
