PROGEO developed a leak location procedure called smartex^® lp. This is far superior to conventional test methods, such as Impulse testing, in safety, reliability and speed.

The conventional method for qualifying a membrane which is in a constantly damp or wet condition is to flood test the membrane. This often requires building dams to maintain the depth of the test water, and can be quite expensive when testing large areas.

It is not possible to use flood testing when a roof is not bounded by walls or parapets, or if the roof is sloped.

These conditions are exactly where smartex^® lp is of most use.

A current is applied to the roofing membrane and a probe is moved along the membrane to pick up
any current coming through the membrane, indicating a leak.

If there is already leakage in the
roofing, one can use a spark tester which is applied to the surface of the roofing in the area where the leak might be. Through this method, the smallest leak can be found.
