A cementitious panel comprising a cementitious core which is fabric-reinforced at the surface thereof and whose longitudinal edges are reinforced by a network of fibers. A panel may be obtained wherein the surface edge reinforcement layers are relatively strong and hard such that a nail or screw may be driven through the edge of panel without pre-drilling and without breaking, even when nailed or screwed almost at the very limit of the edge of the panel. Such a panel may provide a long lasting substrate for humid or wet areas such as shower rooms and bath rooms.

1. A method for manufacturing a reinforced cementitious panel having a reinforced longitudinal edge comprising:forming a slurry comprising a cementitious material and water; forming a core mix comprising a cementitious material, lightweight aggregate and water; providing a panel forming support substrate, the panel forming support substrate being wider than the panel to be made; laying over the panel forming support substrate a band of reinforcing material; laying a first sheet of reinforcing mesh over the panel forming support substrate such that the first sheet of reinforcing mesh overlaps a predetermined portion of the band so as to leave an outer portion of the band uncovered by the first sheet of reinforcing mesh; depositing the slurry on the sheet of reinforcing mesh and distributing it across the breadth of the first sheet of reinforcing mesh so as to form a slurried reinforcement layer of predetermined thickness such that the first sheet of reinforcing mesh is embedded in the slurry; depositing the core mix on the slurried reinforcement layer and distributing the core mix across the slurried reinforcement layer so as to form a core layer of predetermined depth having an upper broad surface; laying a second sheet of reinforcing mesh over the core layer such that the second sheet of reinforcing mesh is embedded in the upper broad surface and overlies the first sheet of reinforcing mesh; bending the outer portion of the band upwardly to an upright position; and folding the outer portion of the band inwardly so as to overlap the second sheet of reinforcing mesh and such that the band defines a U-shaped edge reinforcing component comprising first and second edge strip portions and a bridging portion connecting the first and second edge strip portions, and the bridging portion is non-adhered to and abutting a longitudinal side edge face of the panel.
