A substrate protected by a polymeric lining wherein passageways are provided between the lining and the substrate for channeling of fluids which may penetrate through the lining to the substrate surface. In one embodiment the lining is formed to provide for passages between the lining and the substrate. Mesh attached to the substrate provides for securement of the lining to the substrate by at least partial embedment of the mesh within the lining. Wire spacers are positioned between the mesh and the substrate to separate portions of the lining from the substrate surface and form passageways for channeling fluid which may penetrate the lining. In another embodiment a vessel includes a network of spacers forming a generally parallel array of passageways and at least one passageway transverse to the parallel array of passageways.
