Overview

GPR surveys are conducted using specialized equipment that emits electromagnetic waves into the ground and records the signals that bounce back from subsurface objects. The data collected is then processed and analysed to create a detailed image of the subsurface structure.

GPR surveys provide a cost-effective and efficient method for investigating subsurface features without the need for invasive techniques such as drilling or excavation.

The vehicle towed system is ideal for carriageways and reduces or eliminates entirely the need (and costs) of traffic management. Post processing data allows us to provide 2D and /or 3D digital format deliverables with reports if required. We will always be available to help clarify or explain survey findings post survey delivery.

Frequently Asked Questions

What is a PAS128 Survey?

kk

A document that standardises the equipment, techniques and deliverables of a utility survey. This increases the clients’ confidence in the quality and accuracy when supplied drawings and reports.

Can you find everything underground?

kk

Not always. Although the equipment we use is the latest technology and we have years of experience using these systems - both GPR and EML still have their limitations. We can usually locate services, voids and other anomalies up to 2 metres deep. However, reductive conditions for GPR, such as saturated ground, heavy clay and street cobbles can affect or even negate results. For EML (electromagnetic locators), cut cables, abandoned metallic pipe work, ‘balanced’ or oil filled HV cables and fibre optics can all be difficult to locate and position.
