<p>A permanent formwork building method is provided in which a pair of generally parallel horizontally extending, laterally spaced, extruded formwork panels (5) that are orientated in generally vertical planes is held in laterally spaced relationship by a series of spacer elements (6) spaced apart horizontally to form a void (7) between the formwork panels (5). The void (7) is filled, or partially filled, with a settable bulk material that is allowed to at least partially set before an upper pair of extruded formwork panels (5) and spacer elements (6) is supported thereon and the process repeated as may be necessary with additional pairs of upper formwork panels (5) until a desired height of wall is achieved. The height of the formwork panels (5) is typically from 150 mm to 500 mm. The extruded formwork panels (5) have inwardly integral lipped attachment ribs (14, 15) extending along their length for engagement by cooperating formations on the spacer elements (6).</p> |
