    Compressive strength—or the load at which the stone fails—is usually much higher than the actual load the stone must resist. The industry has established safety factors for various stone types, which help determine the allowable load for that stone. For example, if the safety factor for a given stone is 4, you would divide the compressive strength for that stone by four to obtain the
