GPR Surveys & Post-Processing

Attention to Detail

When we undertake a GPR survey that requires post-processing, radar data is collected in a tightly spaced orthogonal grid, stored, and taken away for analysis away from site. Post processing is a desktop exercise by which an analysist can take considerably more time to analyse and assess the obtained data as well as building up a bigger picture of the area by making comparisons, and joining together the hyperbolas generated by the radar data to create strings in CAD that represent a likely utility service or underground feature. 

​

Features that can be found using GPR are

• Buried metallic and non-metallic utilities

• Underground voids or air pockets, including basements and culverts

• Buried objects, such as underground storage tanks or foundations

• Concrete reinforcement bars
