HYDRO-BAG is simply a dilatating hydraulic cushion that consists of two sheets of high tensile steel coupled with the most modern techniques (among which a LASER automatic unit, see the picture left) and that expands, under the pressure of water pumped at a pressure of 30-40 bar, permitting a maximum dilatation of 25-30 cm (approx 1') and a thrust force up to 1000 tons.



Since HYDRO-BAG is, as mentioned before, 2 mm (0.08") thick only, it can be easily inserted into the wire saw cut, obtained by means of the well known diamond or helicoidally wire saws, of the marble block to be stripped.



It must be stressed that our equipment makes use only and exclusively of running water as a dilatation fluid, and not oil as for the hydraulic jacks, and therefore it is possible to say that HYDRO-BAG is environment-friendly too! Also from the safety point of view HYDRO-BAG offers the best guarantees: Even in the case the cushion blows due to excessive inflating pressure, there will never be any deflagration due to the use of water, and not air, as inflating media. Last but not least, HYDRO-BAG doesn't require any maintenance for the simple reason that after its use (often until it is broken) it can be finally thrown on the scrap heap without regret.



As mentioned before, the thrust force obtainable by a single cushion can reach up to 1000 tons, but by coupling two or more cushions it is possible to obtain higher performances, if the cushions are side by side or combined together in packs



To summarize, HYDRO-BAG is a simple, versatile and economical tool that has revolutionized quarry block stripping thanks to all the positive advantages as briefly described above.
