Our services
Locating underground services with radar and mapping them to the drawing you need, plus 3D scanning of large structures.
GPR surveys and mapping
We locate underground services using ground penetrating radar (GPR) and map them with high-accuracy, sub-centimetre GPS. Positions and depths are marked on the ground and presented as a simple PDF record or a detailed DWG drawing.

3D LiDAR scanning
Using LiDAR scanning equipment, HD GPR creates highly accurate maps of large objects. The maps are delivered as BIM files, a format that engineers and architects commonly use.

Common questions
What is ground penetrating radar?
GPR is a geophysical method that uses radar pulses to image the subsurface. It sends electromagnetic pulses in the microwave band of the radio spectrum into the ground and detects the signals reflected from the surfaces below. It is non-destructive.
Can GPR tell me what an underground service is?
No. GPR detects a difference in density in the soil, not what the service is. That is why we scan with equipment that combines GPR and the electromagnetic principle, which helps with thin live electrical cables.
Do LiDAR scans look like the real thing?
No. A LiDAR scan is a point cloud made from millions of reflected beams of light. The points can be coloured to make viewing easier, but the result will not look like a photo. Professionals use it to measure large objects accurately.
