Ground Penetrating Radar Equipment For Sale
Ground Penetrating Radar (or GPR for short) is the general term applied to techniques which employ radio waves, typically in the 25 to 1000 MHz frequency range, to map structure and features buried in the ground (or indeed in man-made structures). More recently GPR has been used in non-destructive testing of non-metallic structures.
The applications of GPR are many and varied, they include:
- Fracture Mapping
- Voids Beneath Concrete
- Geological Stratigraphy
- Pipe and Barrel Location
- Utility Detection
- Water Table Mapping
- Road Bed Mapping
Geomatrix Earth Science is the UK/Eire sales agents for Mala Geoscience, and we hold their Ramac 100, 250, 500 and 1000 MHz shielded antenna systems for hire. For deep investigations the pulseEKKO 100 is applicable with antenna frequencies of 25, 50, 100 and 200 MHz. For geological investigations we supply the 50 MHz RTA system from Mala Geoscience.

Example Data Sets
NSGG Test Site UXO Master GPR Dataset
Displayed below is a C-scan (depth slice) taken from the master GPR dataset for Area 5 at the NSGG test site, Leicester. Data was collect using a Mala X3M with 500MHz antenna. A grid of traverses orientated NE-SW & SE-NW were acquired at a regular 1m interval. The data was processed, converted to depth and stacked to form a data cube. The depth slice illustrates all of the anomalies detected at 0.25m beneath the ground surface and shows many of the buried targets.
Metallic targets reflect all of the transmitted EM wave energy back to the ground surface and therefore the receiver. This makes GPR a good technique for UXO detection. However voids and structural material (masonry) can produce very similar targets depending on the site conditions and therefore it can be difficult to distinguish between cultural noise and UXO targets.
By integrating the results from the GPR data along with the EM61MK2 and Magnetic data it is possible to collate comprehensive information about the material properties of each anomaly and as a result distinguish between those which are likely to UXO and those which are not.
