GPR surveys in Central Scotland

Many of our clients call a utility survey a GPR survey, and for good reason: ground penetrating radar finds services that standard cable locators cannot. GPR sends radar pulses into the ground and records the reflections from pipes, ducts, chambers, voids and buried structures, whether they are metal, plastic, clay or concrete.

For buried services we use GPR together with electromagnetic location as part of a PAS128 utility survey. For structures, we scan concrete to locate reinforcement and embedded services before cutting, coring or drilling.

GPR for buried services and ground features

  • Plastic water and gas pipes and empty ducts
  • Clay and concrete drains and culverts
  • Chambers, tanks and buried structures
  • Voids and areas of disturbed ground
  • Old foundations and obstructions before piling
  • Detailed GPR grids for congested sites, processed and interpreted in the office

We use the Proceq GS8000 subsurface utility GPR alongside Radiodetection RD8200 and RD8100 locators, with results positioned on OS National Grid and drawn in CAD.

Concrete scanning (ferroscanning)

  • Rebar position, spacing and cover
  • Post-tension tendons in slabs and transfer structures
  • Embedded conduits and pipes
  • Slab thickness and voids
  • Safe zones marked out for coring, drilling, anchors and saw-cutting

We scan with the Proceq GP8000 concrete GPR, marking results directly on the surface and providing a short report with images where required.

GPR Surveys in Central Scotland | Frequently Asked Questions

Q1: What can GPR find that a cable locator cannot?

A: A cable locator (EML) only finds metallic services or those carrying a signal. GPR also picks up plastic water and gas pipes, empty ducts, clay and concrete drains, chambers, voids, old foundations and buried structures.

Q2: Is a GPR survey the same as a PAS128 survey?

A: GPR is one of the detection techniques used in a PAS128 survey. For buried services we use GPR together with EML, and report the results to PAS128 quality levels.

Q3: What is concrete scanning or ferroscanning?

A: Concrete scanning uses a high-frequency GPR to locate reinforcement, post-tension tendons, conduits and voids inside slabs, walls and columns, so cores, fixings and cuts can avoid them.

Q4: Does GPR work in all ground?

A: GPR performance depends on ground conditions: wet clays and saline or heavily made ground reduce depth penetration. That is why we use GPR with EML and explain any limitations in the survey report.

Q5: How much does a GPR survey cost?

A: GPR surveys are priced on the area, the grid density, access and the reporting needed. Send us a plan or photos of the area and we will come back with a fixed quote, usually the same or next working day.
