Concrete wall sawing employs a circular blade on a track-mounted machine that can climb walls and cut ceilings. It is employed to cut walls between 16 inches and 36 inches thick. Uses include cutting openings in concrete foundations, lowering foundation elevation, and full wall removal. This procedure is highly skilled, requiring smooth plum and level openings and is more expensive than other concrete cutting methods. Concrete wall sawing is dustless, vibration-free and quiet.
