Abstract:
A method of reinforcing the anchorage of a frame in an aperture in the wall of a building, the method comprising making a first drilling (14) into the reveals of the aperture from within the aperture, the drilling being between the inner and outer faces of the wall, inserting a reinforcing rod (10,17,22) enveloped by a loose fabric sleeve (11,18) into the first drilling, the proximal end of the rod being secured or securable to a frame within the aperture, and inserting grout to expand the sleeve against the wall of the associated first drilling to penetrate through the fabric and bond to the wall, characterised in that the rod (10,17) is curved back on itself at the distal end from the frame to form a loop, and the plane of the loop is substantially at right angles to the wall, and in that a second drilling is made into the wall between its two faces when the grout has set so that the drill bit passes through the loop, an extra reinforcing rod (26) enveloped by a loose fabric sleeve is inserted into the second drilling, and grout is injected to expand that sleeve against the wall of the second drilling to permeate through the fabric and bond to the wall.
