The invention relates to conductive multi-layer materials for leak detection applications. The electrically conductive multi-layer material comprises a woven glass fibre web (2) having a binding agent (4) and a fire retardant compound (5), which is impregnated with electrically conductive carbon particles (6), wherein one side of the glass fibre web (2) is coated with metallic electrically conductive layer (10) by the means of vacuum deposition.
