Our building entrance has a set of double doors, the door that is fixed is latched to the top frame and to the floor through a hole in a stone saddle. The hole in the saddle is too big for that latch making the door not perfectly "fixed" (ie. it is loosely in place).
What material do you guys recommend could we use to fill the hole in the saddle (smaller than 1 inch in diameter) and then redo the hole?
Any suggestion/guidance will be welcome
