<p>Underlayer, capable especially of being disposed between a slab or support, made of concrete or prestressed concrete, and a covering surface formed by contiguous and juxtaposed flagstones of a tiling or the like. According to the invention, the underlayer in question is characterised in that it consists of a material (8, 12) having a low modulus of elasticity, suitable for constituting a zone of fracture or of weakness in order to transmit the stresses from the slab (1) to the tiling (2). The material of the underlayer may be especially a bitumen or a bonding mortar incorporating a polymerisable resin to which cement has been added. <IMAGE></p> |
