Underground Utility Service Locating

Ground Penetration Radar (GPR)

A non-invasive geophysical method that uses radar waves to scan the subsurface and create detailed images of underground structures, utilities, and anomalies. GPR is ideal for locating buried objects, assessing soil conditions, and mapping structures without the need for excavation.

Utility Mapping

The process of identifying and mapping the location of underground utilities, such as water pipes, gas lines, electrical cables, and telecommunications infrastructure. This is achieved using a combination of techniques, including GPR, electromagnetic induction, and other mapping tools, ensuring accurate utility data for construction or maintenance planning.

Vacuum Excavation

A method of safely and efficiently digging or exposing underground utilities and infrastructure using high-powered vacuum suction to remove soil, debris, and other materials. This technique minimises the risk of damaging existing utilities and is ideal for precision digging in sensitive or congested areas.

Vacuum excavation is a safe and effective way to expose underground utilities to remove soil and more while preventing damage to the surrounding infrastructure.
