Hard mounting has its obvious advantages and can be done from the front or back. To mount the corbels from behind, use multiple screws or bolts that are long enough to enter the corbel but not so long as to go all the way through the corbel. If you can't attach a corbel from the back, a front mount is required. You can simply screw into the front of the corbel and cover the screw heads with putty and sand. Be aware of what you are screwing into and make sure you are going at least 1 1/2 into the mounting surface.
Calculating the Number of Capstones. To figure the number of capstones needed, dividing the length of the wall in feet by the length of the capstones in inches, then multiply by 12. For example, if the wall is 20 feet long and the capstones are 8 inches wide, then the number of capstones needed is [20/8](12) = 30.ultiply the wall's length by its height plus 1/2 a foot to find the total square footage of the wall. That is, calculate. Wall Area = L(H + 0.5) sq. ft, where L is the length of the wall in feet and H is the finished height of the wall in feet.
