Is Your Coat Protective?

CPD (Coating Porosity Detection) Tool

The most effective way that Rock Solid Group has found to identify 'holidays' in coatings is by direct application of the 'CPD' (Coating Porosity Detection) tool.

Especially where excavations have been undertaken to expose a buried pipe, direct measurements using the 'CPD' tool are quick and easy.

The application of the 'CPD' tool is by means of simply brushing the surface of the exposed pipe with a metallic broom. 

Where contact is made between the metallic bristles and the metallic pipe wall, a spark is generated.  It is therefore easily identified where breaks (or holidays) in the coating occur.

The technique is safe and easy to apply.
