Street furniture such as lighting columns and sign posts that are root fixed under ground are subject to structural degradation over time. Unfortunately, the corrosion of the steel is often only visible below the ground surface; Non-Destructive testing is the solution which avoids costly excavation.

​

Our engineers are fully trained to use our specialist ColcheK™  non-destructive inspection machines, which use low frequency electromagnetic technology to compare steel thicknesses below and above ground.
