The 4 Most Common Ways to Demolish a Building
· Wrecking ball demolition, or crane and ball demolition, is one of the oldest and most common methods of building demolition and is typically used for concrete and other masonry structures. The wrecking ball—weighing up to 13,500 pounds—is suspended on a cable from a crane or other heavy equipment. The ball is either dropped onto or swung ...

· Holes are drilled no farther than 12 inches apart. Some holes may be drilled and left empty to allow needed free space for the expansion to occur. Empty holes also are used to stop a crack at the end of a pattern. Although this may be a fairly safe demolition technique, there are still some safety issues to consider.
Concrete Demolition
One of the oldest and most commonly used methods for building demolition, the ball and crane uses a wrecking ball weighing up to 13,500 pounds to demolish concrete and masonry structures. During the process, the ball is either dropped onto or swung into the structure that is to be demolished.
