A prefabricated modular joining assembly for an industrial flooring comprising a module including a prismatic body formed by two half-portions, being separated from one another by a deformable material zone, said half-portions being made of a synthetic resin and having a metal reinforcing framework embedded therein. The joining assembly is made by a method comprising the steps of: providing a box caisson; arranging a rubber membrane in the box caisson thereby separating two zones of the box caisson; arranging in the two zones a reinforcing metal framework; casting a resin material in the box caisson thereby embedding the reinforcing metal framework therein; removing, upon setting of the resin, the module thus formed; and applying the module in a recess formed in a floor at a joint to be restored.

The invention relates to a prefabricated movement joint system with top edge rails providing protection for the concrete floor slab edges. The top edge rails may have a plurality of anchors to embed in the concrete and position the system, which are formed from the parent steel of the rail and not for example welded on. When the top edge rails are joined back to back with the possible use of yieldable fixings they clamp and hold in position possible a nylon or other plastic shaped extrusion and the divider plate thus comprising the whole of the assembled system.
