The conditions for using a discharge-type pinhole detector for concrete are that electricity flows through the concrete substrate during discharge.
The flow of electricity (conductivity) utilizes the moisture contained in the concrete, so it is essential to check this moisture before conducting pinhole inspections. A simple operation of pressing electrodes against the surface of insulating materials such as resin linings, waterproof sheets, or coatings applied to the concrete substrate allows for checking the moisture content of the concrete layer.
