Abstract

A pressure barrier liner (38) has a plurality of low permeability membranes (42, 44) disposed one above the other. A region of relatively high permeability is encapsulated between each adjacent pair of membranes. Pressurizing means may be used to introduce (58) pressurized fluid such as air or water into a selected group of the high permeability regions (46) to pressurize them to a selected pressure or pressures, thereby ensuring that any flow through the membranes (42, 44) or through disruptions in the membranes will be from within the pressurized regions to the regions outside the membranes (42, 44) which encapsulate the pressurized regions, rather than from the fluid storage region above the membranes, through the membranes and into the region beneath the membranes which is to be protected by the liner. Alternatively, depressurizing means may be used to depressurize a selected group of the high permeability regions to a selected pressure or pressures thereby ensuring that any fluid flow through disruptions in the membranes (42, 44) is directed to and withdrawn by the depressurizing means, thus again preventing fluid escapement from the fluid containment region above the membranes, through the membranes and into the region beneath the membranes which is to be protected by the liner.
