Abstract
The liner includes a rib formation with a transverse section configured to mechanically lock the liner to a concrete shell and a joint to allow the rib formation to flex. The joint for the rib formation can comprise a first side spaced apart from a second side with each joined to the transverse section to allow each side to flex with respect to each other. The space between the first side and the second side can be filled with a weld material to add rigidity to the rib formation while allowing it to flex. Each of the first side and the second side can be combined at the other end to a shell. The combined rib formation and shell are spirally wound to create the liner.
