Subsurface and embedded features

Ground-penetrating radar screening

Sends short electromagnetic pulses into the material and records reflections caused by changes below the surface.

What the service involves

Built around the decision you need to make.

The antenna is moved along controlled scan lines. Reflections are interpreted with reference to the material, geometry, access and known site information.
