Complete small breaking tasks of a few minutes effort in the conventional way. This is best done with a hammer drill or a concrete breaker machine. We also recommend using a hammer drill to complete breaking tasks on thicknesses of less that 20cm (8″). Non-explosive cracking agents pay off mainly when larger demolitions are pending. There where heavy demolition machines such as excavators and other large equipments are not available. But naturally, also if a tremor-free, silent demolition is desired or required.
