3 Ways to Break Up Concrete - wikiHow

2018-08-18· To break up concrete, start by covering the concrete with a plastic sheet to protect nearby items from flying debris. For thin slabs of concrete, use a sledgehammer to break it up. If the concrete is too thick to break up with a sledgehammer, you can use an electric jackhammer instead. Whichever tool you use, use a pry bar to lift and remove the pieces of concrete after you break them up.
