Leopoma Method is an electrical method to inspect the roof sealing. This system can be used on almost every kind of flat roof with the exception of EPDM Membrane.
Laopoma Method is especially recommended for such roofs: green roofs, inverted roofs, ballasted roofs. It can show directly and precisely the leakage, without harming the roof layers. The measure set contains two main parts: generator module and detector.
The electric impulse is taken to the roof layer by installation of circumferential ring with positive sign (+) on the roof surface and a grounded wire with negative sign(-), connected to bottom side of the sealing. (scheme 1,2)
When the short circuit appears, the leakage is detected. Detector is connected to 2 manual sensors, which show the direction of the hole in the sealing. The process can be carried out, independently from the roof layer- gravel or grass. The only indispensible thing is to maintain the accurate level of moisture.
The whole process requires well trained technicians. Their knowledge and experience ensure, that the results will be properly interpreted and directly reveal the places of the leaks.
Concrete contains high amount of water. Even when the surface looks dry, the water in material is enough to carry out the process.
Steel Construction under the roof sealing makes the best conditions to carry out the measurements.
Despite the fact, that the wood does not conduct electricity, the Laopoma method is also possible there. Wires of the impulse generator need to be connected in the right manner.
