The need to begin studies in the field of injection anchors is testified by the stronger and stronger request by the designers for instruments and guidelines for the design of anchors and their application in the strengthening of masonry structures. One of the main aims of research is just that of supplying design recommendations which may be of help for designers and technicians working in this field. Laboratory tests In collaboration with the Civil Engineering Department (DICATA) of the University of Brescia a set of laboratory tests were carried on masonry samples in order to check the capacity of the injection anchors with sock in terms of adherence and mechanical interlocking with the substrate. The execution, during the research activity, of a great number of tests has lead to the definition of parameters that are fundamental for the design of injected anchors with sock, as the bond strength at the steel barinjected grout interface an at the injected groutsubstrate interface.
