Ground Penetrating Radar
Protecting underground utilities from damage during groundworks
Ground Penetrating Radar (GPR) allows information about the subsurface to be gained including accurately locating services that are not contained on council plans. It gives the ability to identify buried assets more accurately and non-invasively, providing an accurate understanding of utilities and more. GPR provides a cost-effective and time-efficient solution.
Ground-penetrating radar is commonly used for:
- Infrastructure maintenance
- As-built verification
- Concrete scanning
- Post-tension cable locating
- Locating utilities
- Detecting reinforcing
- Locating sinkholes and voids
- Locating underground storage tanks
- Road and pavement evaluations
Protecting underground utilities from damage during groundworks
KB Contractors mostly use GPR to find pipes and other underground utilities before groundwork takes place. It minimises the likelihood of a water, stormwater or gas pipe being hit during groundworks and therefore limits the impact and disruption to the community and other users.
For this reason, GPR is commonly used for detecting underground utilities. It minimises the likelihood of a water, stormwater or gas pipe being hit during ground works and therefore limits the impact and disruption to the community and other users.
What information can we provide on underground utilities?
GPR can provide high-resolution data for both shallow and deep targets. Metallic and non-metallic utilities can be located. It’s very useful for locating things like pipes and cables along with water leak detection. Air pockets or voids can be identified, along with the water table and bedrock or rock obstructions. With GPR you get a better picture of the following:
- Metallic and non-metallic materials underground
- Stormwater drainage
- Sewers
- Water
- Fibre cabling
- Soak holes
- Fuel and septic tanks
- Concrete scanning
- 2D and 3D site surveys
We recommend using GPR before starting any groundwork. It’s a smart, cost-effective time-saver that allows for a better understanding onsite when working on any underground utilities.
