A method for manufacturing a reinforced cementitious panel comprising: continuously forming a slurry comprising a cementitious material and water; continuously towing an indefinitely long carrier sheet over a support surface; continuously laying an indefinitely long span of reinforcing fibers over said sheet; placing said sheet and its fiber overlay under longitudinal tension; continuously depositing said slurry on said overlay and distributing it across the breadth of the overlay; creating a gap between said sheet and said overlay to be filled by said slurry, said gap substantially spanning the breadth of the overlay and being created by urging a first transverse zone of said sheet to travel through a higher plane than a second transverse zone immediately adjacent to and downstream from the first zone; thereby causing said slurry to embed said fibers; and cutting the reinforced panel into the desired lengths. Apparatus for the continuous manufacture of reinforced cementitious paneling, said apparatus comprising: a forming table and a conveyor belt for continuously feeding a carrier sheet along a predetermined path, means for continuously laying reinforcing fibers over the advancing sheet, means for urging a first transverse zone of said sheet to travel through a higher plane than a second transverse zone of said sheet immediately adjacent to and downstream from the first zone thereby creating a gap transverse to said path between said sheet and the fiber overlay, means for depositing a cementitious slurry on the advancing fiber overlay upstream from said gap-creating means, means for leveling said slurry and distributing it transversely to said path, whereby said slurry is caused to fill said gap and embed said fiber overlay during its passage over said gap-creating means.
