HydroBags. Since the invention of the Hydrobag, it has completely revolutionized bench excavation in quarries! Hydrobags enable the stripping of blocks up to 1000 tons or more, without the need to prepare slots to house jacks. Since the hydrobag has an original thickness of just 2mm (″) it can easily slip into a wire saw cut.
