What we doReliable, consistent and thorough surveys on a large scale

Ground Penetrating Radar (GPR) in many cases is the only practical non-destructive method available to locate non-metallic or non-conductive utilities such as cast iron, PVC or other plastic pipes, concrete, and various composite pipelines.

The successful detection and mapping of underground utilities involves the combination of several techniques with the results synthesised to a single interpreted plot. GPR is rarely the only survey solution to a need but is much more likely to be used as part of a combination approach to deliver the required outcomes.

Applications

  • Utility mapping
  • Void location
  • Sub-structure location
  • Geophysical surveys
  • Concrete inspections

How we do it40SEVEN use the latest technology and ensure the best results

At 40SEVEN we utilise the revolutionary MIRA (Malå Imaging Radar Array) Ground Penetrating Radar (GPR) system for surveying large open areas and roads. The main advantages of the MIRA system are:

  1. Upto 50 times faster than any normal GPR site methods;
  2. No requirement for traffic management;
  3. True 3D data capture, providing increased accuracy and reliability.

The MIRA system was the first commercially available, true 3D, multi channel GPR system in operation in the UK.

The system 40SEVEN use has 16 antennas (400 Mhz) configured in an array that are used simultaneously to gather data in real time at a spatial resolution of 8 x 8 cm.

Unlike other commonly marketed multi-channel systems which could be regarded as parallel, single channel systems, the MIRA system enables fast and true 3D data acquisition.

This means that large areas can be mapped without loss of information. This method is suitable for almost any kind of shallow, subsurface investigation.

With the MIRA system 40SEVEN can map up to 3 ha of open ground or 500m of single carriageway road in a day without the need for costly traffic management.

As you would expect from a market leader at 40SEVEN we are able to advise on the effectiveness of GPR for your site as well as the appropriate methodology and type of system.
