A method and apparatus for forming a curb section of a predetermined length sub-divided into modules by transverse grooves which give the appearance of shorter blocks and provide for fracturing the curb section at those locations. Each module of the curb section includes a rearward fastening projection having a vertical bore for passing a nail to engage the curb section to pavement or other base. Such linear mold sections are all that are required when a curve is dictated. The mold sections are sub-divided into the modules to form the curve. The apparatus includes an open frame moving vertically against a platform and mold shoes for pressing down on the concrete when poured in the mold frame, including plugs for forming the tops of the fastening projections. According to the method, the plugs are removed after the mold frame is lifted, and then the shoes are removed to leave the formed curb sections on the bottom wall.
