Cast members are provided with a liner assembly to protect the cast material from corrosion. The liner assembly is formed of a plurality of curved liner sections having integral joining flanges. A resilient compressible gasket is arranged between opposing flanges and is provided with at least one flange receiving slot for receiving the flange of one of said liner sections to facilitate assembly thereof. Fastening means join the opposing flanges to compress the gasket and thereby provide a liquid-tight joint. Integral flanges are provided at the upper and lower ends of the liner sections to receive a sealant which is squeezed out of the seams formed by the mating sections when joined to protect the cast assembly from corrosion. The liner sections are formed of a material which is inert to the corrosive influences.
