Detecting Unmarked Graves Using Ground Penetrating Radar

Detecting Unmarked Graves Using Ground Penetrating Radar

Over the last 100 plus years Australia has had a history with regards to its extreme weather cycle and uncontrolled crises including:

  • Bush Fires
  • Dust Storms
  • Flooding
  • Hail
  • Cyclones
  • Severe Thunderstorms

In some way or another, all of the above examples have had a catastrophic effect on society and each of our communities within any of the affected areas. After several case studies and various work fronts completed by 123 Locateit (part of the Leaktech group), our conclusion is that due to years of excessive and uncontrollable damage across the country there has been an increase in the demand for Ground Penetrating Radar (GPR) at cemeteries across the country. There are many reasons why there has been an increase in demand for this service, including the below:

  • Extreme Weather i.e. headstones damaged and washed away or moved by flood waters, excessive dust covering grave markers, making it difficult to relocate the graves;
  • Construction works completed previously and a lack of drawings or design to refer back on;
  • Investigations and mapping of various plots to determine current grave alignments, positions, depths etc; and
  • Investigations and mapping of cemeteries to determine areas for future plots.

123 Locateit’s trained and competent staff can assist with all of the above requirements and many more services that we offer.

Ground Penetrating Radar (GPR) is a non-destructive and non-invasive geophysical technique for rapidly imaging subsurface and producing high resolution sections to determine depths, locations and size of the area requiring mapping.

Our workforce is DYBD certified and we are proud members of NULCA. Recently 123 Locateit successfully completed an archaeological GPR survey of two separate cemeteries in south west Queensland, one which was a historical cemetery that dated back to when the town was initially populated.

Leaktech Mobilised to an External Leak Location in Maroochydore

Leaktech Mobilised to an External Leak Location in Maroochydore

There had been an ongoing issue with a large amount of water ponding around the property.

Our crews mobilised and monitored the domestic water meter including the piping (internal & external) and found no movement to suspect any leakage or any draw on the property’s water supply. The teams decided to perform acoustic leak detection around the property and noticed a potential leak, a fire line. After further investigation by step testing the system, we were able to pinpoint where the sound was at its loudest.

The client engaged a civil crew to complete various civil works within the area and to allow further investigation of the suspected leak. The area was excavated, and no leak was located on the fire line within the exclusion given to our client. Leaktech returned to site at no further charge to investigate the area and our crews found and located a separate non-metered fire line within 1 metre of the area being investigated.

Our trained technicians were able to pinpoint the leak which was a redundant but live unmetered fire line which was copper and sleeved with conduit.

In the event that this leak went unnoticed, it had the potential for severe water loss and damage to the property and neighbouring properties.

If you have a water leak, call in the team that has the technology and experience to identify it quickly and accurately.
