Abstract: A formwork system that is readily repositionable to facilitate casting of material is disclosed. A front panel and a rear panel are disposed opposite to each other to define a forming space therebetween to receive the material. The front and rear panels sheath the material so as to retain it in the forming space. A coupler extends over the forming space between the front and rear panels and is pivotably coupled thereto to allow rotation of the front and rear panels about the coupler. A tie is spaced apart from the coupler and extends over the forming space between the front and rear panels. The tie is selectively contractible to cause rotation of the front and rear panels away from each other to move the formwork system from a forming position to a release position to selectively engage and disengage with the front and rear panels with the material.
