Differential Pressure Testing for Water Leak Detection

We use this technique when electronic testing is inappropriate or technically incorrect. By drawing air through a surfactant applied over laps, we can test them for integrity.

We have also adapted this process for testing entire areas or vulnerable or critical sections of membrane, as per the GLA Building in London, when photovoltaic panel installation meant that the roof membrane would be permanently inaccessible once finished.
