About Hydraulic Rock Splitting
Rock has a much lower tensile strength than compressive strength- that's why hydraulic hammers often just can't break hard rock, especially solid ledge. Hydraulic rock splitters take advantage of this weakness, and combined with our over 20 years of dedicated rock splitting experience, we are often the most cost-effective hard rock removal ...
