PLUMBING CORE CUTTING CONTRACTORS Concrete cutting is a process of controlled sawing, drilling and removing concrete. Skilled operators use special saws to cut concrete and asphalt with precision, accuracy and very few mistakes. In the past, concrete cutting companies would use jack hammers to break up the concrete, but that method left everything dusty and messy. Modern concrete cutting techniques involve the use of specialized machinery to leave a smooth, attractive finish of concrete, asphalt, metal and rock.
