Pipe Locating - California

The LMX 200 Premium GPR allows utility locators the ability to easily locate metallic and difficult non-metallic pipes and cables. The advantage of a GPR over a traditional, electromagnetic locator is that the GPR can better see metallic pipes & cable and non-conductive materials including plastic pipes, conduit, concrete duct and dielectric fiber optic cables.

StructureScan™ Mini HR

Pipe Locating - California

The StructureScan™ Mini HR is a high-resolution GPR system for concrete inspection. This system locates rebar, conduits and post-tension cables in depths of up to 16 inches.

Ideal for complex areas, the StructureScan Mini HR can delineate small targets with superior vertical and horizontal resolution.

Radiodetection 500

San Francisco, San Jose and Sacramento

The RD500 is an effective solution for buried, nonmetallic water line locating. The TranSonde is fitted to a fire hydrant or tap and an internal oscillator reacts to water flow. This applies a distinct pressure wave to the water in the pipe that is detected by a seismic sensor in the receiver.
