Holes are created in concrete, through which a mixture or slurry of non-explosive demolition agent along with water is poured. The slurry, because of the presence of selected chemicals, will expand underneath the surface of the concrete, which will crack the concrete for easy removal. Non-explosive demolition has some serious advantages that cannot be ignored.

The use of explosives is regulated in many regions, and for such areas, non-explosive demolition agents are the only options available.
