Heritage Site Investigations

Grave Sites / Cemeteries

The non-destructive nature of techniques such as Ground Penetrating Radar (GPR) and resistivity have proved very popular for the investigation of known and potential gravesites. To date, GBG Australia staff have located burials at Aboriginal, Historic and Contemporary sites. We are able to locate unmarked graves and determine the depth and orientation of these features. In some cases, metal detection is used to detect associated metal artefacts. To fully understand the stratigraphy of the site, we also plot utilities and natural geomorphologic features such as the water table. All reports are strictly confidential unless otherwise requested by the client.

Heritage Buildings

Individual building materials are homogenous to high frequency GPR, and in structured combination provide readily detectable electrical interfaces. Radar can be used as a non-destructive and non-invasive method of providing information about the internal construction and condition of buildings, walls and other structures.

• Construction information: wall, slab and soffit thickness, beam placement
• Location of internal metalwork and corrosion, eg ties and reinforcing rods
• Detection of voiding and invisible cracking
• Assessment of stone facades: delamination, areas of high moisture content

Status Monuments

Pieces of cultural importance may be effectively surveyed to determine the following:

• Identification of base/support construction
• Condition assessment
• Detection of structural weaknesses such as voiding and micro-cracking.

GBG Australia have undertaken investigations of:

• Archaeological Sites
• Concrete Structures
• Contaminated Sites
• Heritage Sites
• Pavements
• Railway Infrastructure Assets
• Utility / Service Location
