Title:
METHOD OF DETECTING A LEAK IN A LIQUID APPLIED MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2024/028206
Kind Code:
A3
Abstract:
Described is a method of detecting a leak in a water impermeable liquid applied membrane comprising the following steps: a) applying a water impermeable membrane M onto an electrically conductive layer ECL located on a support substrate SuS by the application of a reactive composition in liquid form on the electrically conductive layer ECL and letting the applied composition cure; b) applying electrical voltage between a conductive detector CD on top of the water impermeable membrane M and the electrically conductive layer ECL such that current will flow between the electrically conductive layer ECL and the conductive detector CD through any leak located within the water impermeable membrane M; c) sensing the current between the electrically conductive layer ECL and the conductive detector CD so as to detect any leak.
