Starting from the second decade of the 21st century they are used for the structural rehabilitation of existing buildings, in particular made by masonry (existing and historical) or by reinforced concrete, to increase their load-bearing capacity under both vertical and horizontal loads (including seismic ones).

Various typically disposable aids, mainly of plastic, are produced to secure and align cast-in-place anchors prior to concrete placement. Moreover, their position must also be coordinated with the reinforcement layout. [3]
