What is PROSTAR?

"PROSTAR" is a  soundless,  safe and non-explosive demolition agent, its chemical name is Calcium Hydroxide,  which is quite different from ordinary demolition agents such as explosives and dangerous materials, it does not cause any fly rock noise ground vibration gas dust or any other environmental pollution when used properly.

As requirements for demolishing rock or reinforce concrete in construction increase in tight quarters the use of explosives agents are becoming more restricted as far as safety and environmental pollution problems are concerned

"PROSTAR" is a solution.

?PROSTAR? as a material in powder form that expands considerably after mixing with water. This expansion., when is restrained in pre-drilled holes, generates significant expansive pressures which are far away enough to break, cut or demolish any type of rock and concrete structures. Water and ambient temperature are the most important variables in influencing the generation of expansive pressure.

The principles applied in using ?PROSTAR? are very much similar to those ones followed in traditional blasting techniques. As for explosives, holes must be drilled to contain ?PROSTAR?. Which must be mixed with a measured quantity of water and poured into the holes. Few minutes after pouring a reaction of hydration is taking place generating heat and crystallizing and expanding while hardening. If hydration takes place under confinement, significant expansive pressure will result, No need for detonator, ignition and professionals operators.    


?PROSTAR? does not make noise, explode or generate fly rocks, vibration or toxic fumes. It is completely harmless and enviromentately friendly.
