Electric Capacitance/Impedance Testing in Flat Roof Inspections
Electric capacitance/impedance testing is a non-destructive testing technique used to quickly and accurately identify water entry pathways and areas of entrapped water within a roof construction. This technique is based on the ability of a material to store electrical energy.
It involves placing a moisture meter on the surface of the roof to send a safe electric current into the roof without penetrating the roof membrane. If the material is wet, the dielectric properties of the material would produce a higher meter reading than it would if the material were dry.
This test is often performed in conjunction with infrared thermography and/or Dec Scanning in flat roof inspections to help simplify the job of tracing the moisture back to the point of entry.
