GROUND PENETRATING RADAR
GPR is a high resolution electromagnetic survey technique designed to investigate anomalies in the subsurface of the earth and surrounding infrastructure.
Applications of GPR
How to apply the best GPR requires extensive competency. SSI Test, Inspect and Consult can specify different GPR units with variable frequencies to solutions that are most suitable.
The versatility of GPR is diverse but there is no one universal GPR unit that can fit all requirements.
Our GPR surveys can provide accurate depth estimates, identify sub surface anomalies and provide 2D and 3D imagery.
Road, Rail, Tunnel and Infrastructure
Asphalt layer surveys
Identification of sinkholes
Deterioration of base road and rail ballast
Sub surface structures beneath manmade objects
Bridge foundation / footing surveys
Wall anomalies and thickness
Subsurface tunnel anomalies
The quality control of repairs – real time monitoring of the injection of specialist grouts and the latest polymer resins
Utility Location and Mapping
GPR should be considered as a complementary survey tool for utility locating and mapping:
To confirm the location of a radio detection anomaly
Improve depth estimates
Detects additional features
Location of plastic and non ferrous pipes
Locating large volume and long running water leaks
Rapid reconnaissance surveys – due to fast data collection
Internal sewer inspections and surrounding soils
Comparable to some other methods, like seismic and electrical resistivity, GPR is used to map the layering of materials, water table levels, cavities and other geological phenomenon.
GPR technology has become a valuable tool for archaeological studies and surveys. It allows for a potential site to be mapped and evaluated before the actual digging – focusing the efforts and preserving underground artefacts.
