Ground Penetrating Radar Inspections

Ground Penetrating Radar

Ground penetrating radar (GPR – Structure Scan) can assist with the location of underground services in many instances where standard radio-detection methods cannot. GPR technology can assist in the location and depth of:

  • Water mains – all types, including asbestos, blue brut
  • Pipes – plastic, poly, pvc
  • Fire main valves
  • Fibre optic cables
  • Road crossings
  • Rising mains
  • Buried manhole covers
  • Underground
  • Underground tanks and pits

Ground penetrating radar is a non-destructive geo-physical method which uses radar pulses to ‘map’ an image of shallow subsurface features, down to approximately 6 metres. The data collected from the radar sweeping across the surface is collected to construct a view of the subsurface. Varying soil conditions can impact on the result.

Concrete Scanning

Our concrete scanning equipment can “see through” most concrete.

Before you drill or cut a core hole through concrete, we can show you where reinforcing, stress beams, cables and pipes are in most slabs, saving time and money.

Keep your team safe

The use of non-destructive high-resolution ground penetrating radar (GPR – Utility Scan) before you core, cut or drill concrete, can greatly reduce the risk to workers cutting through live cables or other hazards. Leaktech’s concrete scanning can accurately indicate the presence and depth of pipes, cables, steel reinforcing, post-tension ducts, any voids in concrete and suspended slabs. This technology greatly increases worker safety.

DBYD Certified Locator

Before You Dig

Don’t rely on the free plans available from Dial Before You Dig for accuracy, their plans are a guide only. Their ‘Duty of Care’  guidelines they recommend the use of Accredited Plant Locators (APLs) for all excavations. There have been numerous occasions where our Leaktech APL technicians have located underground cables when there has  been nothing indicated on the Dial Before You Dig plan for that location.

To be safe, before you dig, call Leaktech – we can safely locate all underground services.

Yes, it is highly recommended to locate and mark Critical Underground Services before commencing any construction or excavation work. This helps ensure the safety of your team and the project, prevents damage to utilities, and avoids costly delays.

At LeakTech we use a non-destructive high-resolution ground penetrating radar (GPR – Utility Scan) to accurately indicate the presence and depth of pipes, cables, steel reinforcing, post-tension ducts, any voids in concrete, and suspended slabs to increase worker safety.

How do you mark the located Critical Underground Services?

We use industry-standard colour codes and marking flags to indicate the type and location of each service. These markers are typically placed above the ground, outlining the path and depth of each service.
