The shuttering system consists of a pair of concrete panels with facing channels and welded reinforcing mesh (9) between them. The panels are cast on flat horizontal surfaces with the channels formed by shells in sections (5a, 5b) of a material made or treated to be non-adhesive with regard to the concrete and held together by dovetail-shaped projections (7a, 7b) and locking strips (6). Once the panels have been cast, with channels running the height of the wall or length of the floor, the shells are removed, and once the panels are installed as shuttering the channels are filled with concrete.
