Abstract: A concrete formwork spreading device includes a tie rod including opposing ends, and a pair of end caps connected to the opposing ends of the tie rod. Each one (1) of the pair of end caps includes a contacting face, wherein the contacting face is flat. Each one (1) of the opposing ends of the tie rod is one (1) of permanently connected or removably connected to an associated one (1) of one (1) pair of end caps. The contacting face of each one (1) of the pair of end caps is spaced apart by a distance, the distance is equal to a thickness of a concrete wall formed using the device. The distance between the contacting face of each one (1) of the pair of end caps is one (1) of fixed or adjustable.
