Ground Penetrating Radar (GPR)
A new addition to our equipment and services list is Ground Penetrating Radar (GPR).
Ground-penetrating radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface. It is a powerful tool for geotechnical investigations, as it can provide high-resolution images of buried objects and structures.
How GPR works:
GPR works by transmitting radar pulses into the ground and then measuring the time it takes for the reflected pulses to return to the surface. The strength of the reflected pulses is also measured. This information is used to create a radargram, which is a cross-sectional image of the subsurface.
Applications of GPR for geotechnical investigations:

Applications of GPR for geotechnical investigations:
- Mapping buried utilities: GPR can be used to map the location and depth of buried utilities, such as pipes, cables, and sewer lines. This information is important for planning construction projects and for avoiding accidental damage to utilities.
- Locating underground storage tanks: GPR can be used to locate underground storage tanks (USTs), which are used to store hazardous materials. This information is important for environmental investigations and for planning the cleanup of contaminated sites.
- Investigating foundations and structures: GPR can be used to investigate the condition of foundations and structures, such as bridges and buildings. This information can be used to identify potential problems, such as cracks or voids, and to plan repairs.
Advantages of GPR:
- GPR is a non-destructive method, which means that it does not damage the ground surface.
- GPR is a relatively quick and easy method to use.
- GPR can provide high-resolution images of the subsurface.
