This is usually done by drilling a hole into the concerned obstacle and then filling it with Calcium Hydroxide at 15 degrees and then it takes about 12 hours settling time during which it expands and cracks the rocks or concrete.
This is used for deepening wells, breaking away concrete structures (demolition man) and it tends to be expensive than electric blasting which is highly explosive and noisy by nature and it often requires explosive permits to do the job.
Thus this is a solution to clearing large boulders where blasting or explosions are not advisable as in case of proximity to roads, and dense population.
Presently this is available through importers from china under a product name of Crack A G which is sold around the price of Rs 40/- a Kg and this service is offered at Rs55/- per feet of the drilling hole.
