Hydraulic Rock Splitting
Certain geologic formations (ex., diabase) are nearly impossible to hydra-hammer due to the very high compressive strength of the rock. When blasting is prohibited or very difficult because of project specifications or government regulations, hydraulic rock splitting may be the most economical alternative. Hydraulic rock splitting is often appropriate for boulders located in basement excavations. Hydraulic rock splitting does not require any permits so there is no waiting for permit approvals.
