Stone stuck at depth of 1080 ft. Need advise to break this

There’s a stone stuck at 1080 ft of my bore well . It residential purpose in Bengaluru. Total depth is 1400ft . I need to keep the motor at 1300 ft however could not do due to stone stuck. I already put casing pipes until 1080 ft could not insert further due to stone stuck. Need advise to clear this stone with minium cost given that I already spend 6lacs.

have you put a casing pipe to avoid silt till 1080 feet?? Very expensive installation. If there was no silt pipe, you could have gone for a rebore. Reach out to this guy waseem - 9845889634
