The dipstik® solved the problem that duty holders had of testing columns that were difficult to access with other test methods.

It provided reliable and proven results that came from the oil and nuclear industries where cracks and defects in shafts could go undetected. The dipstik® was able to replicate this method and provide a clear picture of the degradation of column material above and most importantly, below ground where corrosion cannot be seen.

To date, Dipstik® technology has found hundreds of corroded columns and is used on over half a million columns a year, across the UK.
