As a new product of Poliex, EGK due to its characteristics, features and applications represents real progress compared to all previously known means used for breaking, cutting and splitting construction materials (concrete, reinforced concrete constructions, granite, marble, stone blocks etc.) Unlike conventional explosives EGK creates quasi-static pressure gases in sealed areas which leads to splitting homogeneous structure of the rock without explosion and waste of materials. Benefits of EGK are reliability, operational and transportation safety, and the fact that there are no byproducts and harmful substances that can directly affect living and working environment in the process of use, since its combustion it releases water, steam and carbon dioxide.
