Both methods work by applying lateral forces against the inside of holes drilled into the concrete, and can do virtually any job other demolition methods are capable of. However, rather than shattering the concrete into bits as dynamite and impact tools would, the lateral forces build up over time to crack the concrete into smaller sections.

Concrete is usually reinforced with a metal mesh inside. Today''s techniques tend to pulverize with brute force which creates a lot of dust and uses a lot of energy. Outcome of the operation creates a mixed mound of waste material which needs to be separated in order to be reused or sold as second grade metal, or as a filling material.
