bridge decking Testing Equipment


Waterproof membranes applied to reinforced concrete bridges can be tested with high voltage to find any defects in the coating.

The testing process can detect blow holes, inclusions or thin areas in 'sprayed-type' membranes. Because the concrete contains a small amount of water, it is electrically conductive and a DC Pinhole Detector can be used to create a high voltage which is passed over the surface by the use of a brush electrode. An alarm will sound to identify any small defects which can be rectified so that the integrity of the coating can be verified.
