If you need to mend close to the edge of a brick or stone pier in order to hang a fence or repair a letterbox or nameplate, drilling as well as making use of screws and bolts which expand in their affiliated electrical outlet may split or split the masonry. The means to get over this is to fix using chemical resin injected into a pre-drilled space. An area, or stud, of threaded bar is at that point screwed and fixed into the hole.
