A method for repairing and/or waterproofing and/or insulating and/or reinforcing and/or restoring the structural integrity of wall systems, which it consists in providing spaced injection holes (3) within a wall system in a manner suitable to pass through cavities (2) that exist in the wall system (1), inserting injection tubes (4) in these holes (3), and then inserting a substance (5) that expands after injection as a consequence of a chemical reaction so that the substance (5) reaches the cavities (2) connected to the injection holes (3) or are proximate thereto, the injection tubes (4) being, preferably gradually retracted along the injection holes (3) in the opposite direction with respect to insertion, to allow the substance (5) diffusing in cavities crossed by the injection holes (3) or proximate thereto.
