what is crack-rock?

crack-rock is a highly expansive mortar to demolish and cut rocks and concretes.

crack-rock swells when poured into a 
hole and develops a pressure higher than 7500 t/m2 on the hole walls, thereby breaking them open.

 It is non-explosive, therefore supervision of trained personnel is not essential.
