CONCRETE SCANNING

When in doubt, daylight!  Daylighting is a common field term used to reference the "exposing" of a buried utility with non-destructive methods.  A hydrovac truck is a common approach to expose the location of a line along a trench or at a specific location.
Using GPR and EM, we can locate metal pipes, plastic pipes, conduit, sumps, abandoned lines and other subsurface structures. Additional locate tools include camera scoping and sonde tracing for plastic pipes (commonly storm and sanitary sewer lines).
