    Publication number: 20210025276
    Abstract: A process (10) for the sealing of joints (G) between prefabricated ashlars (C) or similar construction elements, comprising the following steps: inserting of a sealing strip (11), of plastic material, in a joint (G) between two adjacent prefabricated ashlars (C) so that the sealing strip (11), once inserted, extends along the joint (G) to be sealed; and injecting, by means of an injector tool (A), of a sealing resin (12) into the interior of the joint (G), so as to distribute, thanks to the containment and confinement action of the sealing strip (11) inserted in the joint (G), the sealing resin (12) along the extension of the joint (G) and therefore fill it; wherein the sealing strip (11) has, preferably, in section, a special configuration showing a plurality of inclined fins (11c), protruding from a central body (11b), apt to co-operate with the walls of the joint (G) in which the sealing strip (11) is inserted, so as to prevent the escape of the sealing resin (12) and the detachment of the sealing strip
