Anytime a contractor, or even a homeowner, needs to dig into the ground, they run the risk of hitting utility lines and pipes. Not only can this be expensive if lines are accidentally cut or damaged, it can also be very dangerous. Gas lines can explode, and electric power lines
They can cause electrocutions and fires. While the water may not be as dangerous, a sudden release of water could cause trenches to collapse, trapping workers below the surface.
Before opening any trench, our company can be contacted and a utility locator visits the site before your project begins and locates the exact area and depth of each type of utility on the property. With this information, workers can run their business safely and reliably.
Location technicians use a variety of electromagnetic sensors and georadar or GPR (Ground Penetrating Radar) equipment:
- Tasting of location of services. It allows you to physically see a segment of the service, allowing you to intuit its alignment.
- EM system (electromagnetic locator). Radiodetection system that allows a pipe or cable to be followed along its route.
- Single-channel or multi-frequency georadar or GPR (Ground Penetrating Radar) system. This technology allows in situ and real-time marking of buried pipes by a qualified operator.
- Multi-channel GPR system. It allows to obtain continuous information of the subsoil in 3D quickly, it requires a qualified operator.
It is recommended to get in touch well before you start digging or start designing. Depending on the scope of the project, it is often essential to know the exact locations and depth of utility lines during the early stages so you don’t have to repeatedly modify projects.
There are different methodologies to locate affected services in the works that imply different degrees of precision and time / cost:
- Detection and marking with espai in the same place of the different affected services.
- Detection, marking and delivery of a small planimetry with external references.
- Massive detection of 3D services, for this methodology a mesh of high density parallel profiles is acquired that allows to build a georeferenced 3D georadar image and that in the office is interpreted in 3D CAD.
