Abstract
A liquid storage tank having at least a liquid-retaining wall and usually a structural outer wall and including a porous material therebetween. The porous material forms a structural interconnection with the wall or walls to prevent them from peeling apart and is also typically adapted to wick any liquid which comes in contact with it. Further, the storage tank may have sensors associated with the porous material at strategic points for detecting the presence of a leak. A method of making a storage tank for a liquid is provided wherein at least a liquid-retaining wall and usually a structural outer wall is provided or formed. A porous material typically having a barrier layer formed on one surface thereof is applied to a surface of one of the walls by placing the surface opposite the barrier layer thereon. Further, at least one type of liquid sensor may be installed in the porous material at strategic points for detecting the presence of a leak in the storage tank.
