   • 1980, Romanian Review - Volume 35, page 97:

     In these cases, it has been envisaged the pulling off of the emplectons of the wall, the removal of the roots, the placing back of the loose blocks and finally the placing back of the emplectons so as not to exert too great a pressure on the paraments of the wall.
