Abstract
A collapsible formwork element, the element including: a pair of opposing side wall panels; and at least one connector member extending between the side wall panels, wherein the formwork element is movable between an expanded configuration, wherein the opposing panels are spaced apart, and a collapsed configuration, wherein the opposing panels are relatively closer together.

A collapsible formwork element, the element including:
- a pair of opposing side wall panels;
- and
- at least one connector extending between the side wall panels,
- wherein the at least one connector includes at least two hinge portions that permit movement of the element between an expanded configuration, wherein the opposing panels are spaced apart, and a collapsed configuration, wherein the opposing panels are relatively closer together, and
- wherein the hinge portions are formed of a material that is more flexible than the material forming the remainder of the connector, which is substantially rigid, so as to provide a hinge type action.
