Abstract
Abstract A composite construction is provided comprising a load-bearing substrate, an impermeable liner, and disposed therebetween a circulatory system defined by a network of cells having side walls which are generally in lateral orientation to the liner and the load-bearing substrate, at least some of said side walls having apertures therein whereby at least some adjacent cells are in communication with each other. This construction has the capability of being formed with a variety of flow paths through the circulatory system whereby provision may be made for leak detection, inert gas circulation, heat exchange and the like.
