Zusammenfassung:	A composite sheet 27 for lining a liquid container comprises two outer layers of insulating material between which is a central layer 2 which is divided into electrically conductive but electrically separated fields 7 and 8. Each field comprises two networks of conductive pathways 21 and 22 to which, in use, an electrical potential is applied. If a leak occurs the liquid within the container penetrates between two adjacent pathways 21 and 22 and an electric current flows which can be used to initiate a signal indicative of the presence and position of the leak.
