What we do
Reduce the risk of striking what you can't see.
Underground Service Locating
Trace and mark detectable utilities before you dig.
Ground Penetrating Radar
Investigate metallic and non-metallic targets without digging.
Concrete Scanning
Check slabs and walls before coring, drilling or cutting.
Electrical Cable Locating
Find detectable cables and conduit runs before trenching.
Water, Sewer & Drainage
Locate detectable pipes and drainage routes.
Pre-Excavation Investigations
Combine locating and GPR before major works.

Photos and a clear summary, including limitations.
Who we help
Built for the trades that dig, drill and cut.
Example scenarios
Common jobs, clearer decisions.
Illustrative scenarios based on common site work. They are examples, not completed ASGPR projects.
10 m sub-main from switchboard to shed
The risk
A new conduit trench crosses a yard where the water service, NBN lead-in and sewer branch are not shown on any plan.
What ASGPR does
Trace live and passive services along the 10 m route, then scan with GPR to check for non-metallic pipes crossing the trench line.
What you get
Paint and flag mark-outs on the ground, approximate depths where they can be estimated, and a short summary with photos.
Ground penetrating radar
How GPR reveals what's underground.

Plans vs scanning
Plans tell you what's recorded. Scanning checks the site.
e.g. Dial Before You Dig
Plans from asset owners
- Show registered assets only
- May be approximate or out of date
- May not show private services
Use both
On-site scanning
- Checks what is detectable on your actual site
- Validates and supplements plans
- Marks findings on the ground for your crew
- Has limits, and we'll tell you what they are
