Ground Penetrating Radar (GPR) offers a cost-effective non-destructive (ND) method of building inspection and investigation. Non-destructive techniques generally prove cost-effective because they are non-intrusive and do not require the repair of the building fabric and decorative finishes.
GPR can be used to determine construction detail when no as-built drawings are available (or to confirm that drawings that are available are correct) and assessing the feasibility of proposed building works. Ground Penetrating Radar is silent, does not emit any harmful radiation or fumes and causes minimum disruption in occupied buildings. This makes it particularly useful for use in historic/listed buildings or where fine decorative finishes are present, where the use of more conventional techniques would result in extensive and unnecessary damage.
In building investigation, GPR can be used for:
- Thickness measurement of members such as floor slabs and walls
- Basement and floor slab construction
- Size and orientation of structural members
- Location of metallic components such as fixings, clamps and dowels
- Rebar mapping of reinforced concrete
- Flue and conduit location
- Location and extent of voiding
- Foundation location
Abseil GPR survey of building to locate embedded metal. GPR is a non-destructive survey method, which makes it particularly suitable for historic and listed buildings.
