The shuttering panel is made from at least two surface layers (2,4) with spacers (4) between then and gaps between the spacers for reinforcing of polypropylene with the same structure as corrugated cardboard, and the spacers are cylindrical in shape, set in regular lines between the two surface layers. Adjacent shuttering panel sections are joined together by narrow strips of the same material and construction which fit between their open ends, The shuttering can be erected on site and filled with concrete to make the wall. |
