We keep innovating and improving to be a leader of air pushing bag, our unique design without air hose inside makes it easier to put air pushing air bag into crack between blocks. Through our experiment and cooperation with thousands of quarries around the world, introducing Italian advanced equipment and raw material, especially adopting our new technology and new materials, quality of air pushing bag has a new qualitative leap, thickness is same as less than 8mm, but more strength, more reliable quality and longer designed life-span more than half a year, especially more safety. Betopper air pushing bags, your best choice!
