Ground Penetrating Radar Services
ARTEMIS TECHENG specializes in providing subsurface mapping and imaging services using the non-destructive method (NDT) of Ground Penetrating Radar (GPR).
- – GPR uses electromagnetic pulses to image the subsurface and everything in it at depths of up to and beyond 10 metres.
- – It is the safest non-destructive method and is ideal for use in public places for subsurface imaging and detection of metallic, non-metallic objects and underground utilities – networks.
- – Data acquisition with GPR is relatively quick and easy, making it suitable for mapping large areas.
- – The combination of high resolution and high speed of data collection make this method the most ideal for solving shallow geotechnical problems
Artemis TechEng is composed of an experienced team of geologists and engineers, combined with our advanced equipment and technology offerings, make us the first choice for clients who require accuracy, detail, technical and time consistency in our commitments and reliability in their subsurface mapping and imaging requirements.
APPLICATIONS OF GPR
- – Geological mapping and subsurface imaging,
- – Geotechnical and infrastructure works,
- – Foundation Quality Surveying
- – Detection and mapping of utility installations (sewerage networks, water supply, natural gas, pipes, cables)
- – Road pavement quality control,
- – Detection of Archaeological Finds (detection of tombs and structures)
- – Detection of buried unexploded ordnance (UXO).
The main purpose of our company is to provide solutions by accurately locating the depth and position of metallic or non-metallic objects in real time, using the GPR.
The information is displayed on a screen in the form of a graphic (radargrams) as shown in the image below.
Geophysical data from GPR after the processing procedure can also be displayed as depth-slices as shown below.
Specialised geophysical data processing software is used to process and interpret the geophysical data.
Illustration of the GPR track – lines (white lines) as shown in the editing software.
The results – deliverables of GPR are processed and interpreted giving the final recipient useful information about what objects exist in the subsurface while all findings are presented with geo-referenced topographic accuracy (R.T.K).These deliverables include the following:
- Technical Report (description of field work, theoretical background of GPR, results in appendixes in the form of tables and illustrations – screenshots.
- Display of results in kmz/ cad files.
- Snapshots of data from the processing software.
