They are usually anchored to the wall and secured to each other and to the wall by a layer of cement. Some methods make use of grooves in lower and upper edges of each block, into which a cross-shaped connecting element is inserted. In addition, some of these methods use planking and do not become permanently stable until concrete is poured behind the cladding blocks.
Some known methods also utilise dry cladding with bridging members as brackets. These methods, however, require individual attachment of each bridging bracket to the wall being faced, an arrangement requiring some skill.

BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will be described below by way of example only and with reference to the accompanying drawings in which:
Figure 1 is an isometric view of a tap or decorative face of one embodiment of a construction element according to the invention;
Figure 2 is an isometric view of one embodiment of a construction element according to the invention views from behind;
Figures 3 are two further embodiments of the decorative face of a and 4 element according to the invention; and
Figures 5A are alternative embodiments of the rear hollow of construction to D elements according to the invention. DETAILED DESCRIPTION OF THE DRAWINGS
Referring to Figure 1, a construction element (1) comprises a generally planar, synthetic plastics material, parallelepipedical element having a decorable exterior face (2). In sue, the element (1) is securable to a wall (not shown) to display its decorable exterior face (2). In this embodiment the decorable exterior face (2) is slightly roughened and the element (1) is sprayed with a comminuted sandstone and mortar mixture so that its exterior face (2) simulates a rough hewn sandstone block.
In use, the element (1) is secured to a brick or mortar plastered wall by mortar or by any suitable adhesive. A multiplicity of elements (1) are so secured to the wall and aligned relative to one another to create a visual impression that the wall is made of rough hewn sandstone blocks.
Referring particularly to Figure 2, the hollow rear of the element of Figure 1 is shown. The hollow is formed from the upstanding side walls (3) of the element (1). To provide rigidity to the element (1) and to increase the surface area of the rear face (4) so facilitate securement to a wall, upstanding diagonal ribs (5) lead from each corner (6) to meet at a centrally positioned tubular formation (7).
The element (1) is manufactured by moulding a synthetic plastics resin. This can be done in a factory environment or on a building site. In a preferred method the element (1) is injection moulded although it can also be rotor moulded or vacuum formed.
Once the resin has cured a decorative coating is sprayed on the element although, depending on the type of finish that is desired, it could be applied with a brush or dipped. Finishes that can be applied to the element include natural stone finishes such as granite, sandstone or quartzite, marble finishes and artificial finishes which are glass chips that are added to the coating.
The plastics material is a resinous material and can have one or more of a UV stabilizer, a biocide and/or natural sand or stone added to it before it is moulded.
Referring now to figures 3 and 4, alternate embodiments of finishes that can be simulated are shown. In Figure 3 the finish is intended to resemble a multiplicity of irregularly shaped stones (8) and it is achieved by sculpting the mould or it can be achieved by placing small stones in the mould although this will add to the weight of the element (1) although it is envisaged that such elements could be used as garden paving.
In Figure 4 a wood grain finish is simulated and it is envisaged that such elements (1) can be used on interior walls of buildings to provide an aesthetically pleasing appearance.
Referring to Figure 5, four different configurations of ribs for facilitating securement of an element (1) to a wall (not shown) are illustrated as 5A to 5D. The arrangement illustrated in Figure 5A has already been described with reference to Figure 2.
In Figure 5B the ribs (5) are at right angles to the side walls (3) and have a tubular formation (9) at each of their intersections. The ribs (5) in Figure 5C are diagonal while the ribs (5) in figure 5D form a series of squares on the underside of the decorative face of the element (1).
