Low- Energy and- Non-Detonating Formations

An emerging trend is the development of explosive products specifically designed for controlled demolition and reclamation rather than production blasting. Low- energy explosives, such as certain binary emulsions and non-detopitating grouts, generate less noise, duss, and fly rock. These formulations are specilarly useful in urban or ecologicaly sensive setting where conventional blasting would be unicable.
