Abstract
An internally braced permanent formwork for concrete foundation construction is provided in order to achieve a quick and simple assembly. The formwork comprises a base member laid on the ground having a perimeter recess on an upper surface for receiving components of the formwork. One or more permanent outer boards forming an outer periphery of the foundation are provided and coupled to a plurality of spaced internal bracing components to prevent collapse under the pressure of wet concrete.
