We use electric high-powered wall saws that have the capability of cutting up to 30" deep. We also will use a chain-saw to prevent over cuts at the corners of openings to preserve the structural integrity of the opening. We have used wall saws to cut in windows and doors into solid concrete walls. Wall saws can also be used for the removal of concrete walls.
