Ground Penetrating Radar Surveys

Terrascan follow industry best practices and use a combination of well-established technologies available on the market to achieve the best possible utility location results. Ground Penetrating Radar (GPR) technology, especially dual-frequency radar, has fast become the most reliable means to detect non-conductive objects that cannot be detected by EM and RF technology.

Terrascan use GPR technology as well as eletromagnetic and radio frequency to locate and determine the depth and position of metallic and non-metallic utilities and services. The wide scope of radar means we can also locate underground storage tanks and any associated ducting, sub surface concrete structures, voids and any other ground variations that may exist at your site.

As part of our radar service we can record and analyse data by making use of our advanced GPR data processing software giving you greater certainty of located targets.

The recent introduction of BSI PAS128 specification has provided a long awaited standard to help understand how targets have been located which ensures you have all the information you need when assessing your survey results. We offer drawings to the PAS 128 standard and can provide drawings to this specification on request.

What is BSI PAS 128 Specification?

This new British Standard has been created by the industry to designate 4 levels of traceability to all marked utilities. This makes it clear how a utility is found so you can better prepare your site.
