Abstract

A thin-walled, flexible element made of PVC (or other material subject to heat expansion) for use in stay-in-place modular concrete formwork is characterized by at least one longitudinally extending reinforcing projection or rib to prevent oil canning of the element. Preferably the projection or rib has a surface which is perpendicular to the wall formed by the formwork. The invention is particularly adapted for use where the concrete is not in direct contact with the portion of the element which is to be reinforced, such as when a layer of insulation is interposed between the element and the concrete.
