Hydro Bag

This has happened in the marble and stone quarrying industry , specifically for stripping blocks from the mountain .
HYDRO-BAG has completely upset bench excavation in quarries .
The revolutionary aspect of the HYDRO-BAG equipment lies basically in the possibility of stripping blocks up to 1000 tons or more , without the need to prepare slots to house the jacks since the HYDRO-BAG has an original thickness of just 2 mm ( 0.08 ) and can be easily slipped into the wire saw cut .
