DREDGED IN ROCK WITHOUT EXPLOSIVE
DREDGED IN ROCK WITHOUT EXPLOSIVE
(OP)
Dear colleagues, in order to carry out dredged works in a conglomerate the employment of explosive were not allowed; however, it was possible to remove it applying an apparently liquid “substance” that was able to fracture the rock and made easier their later removal. Does somebody know this substance? Can somebody tell me where I may find information about it?
Thank you.
Thank you.

If by dredging you mean underwater, you might be able to use the cement in a waterproof sock, but as for a liquid that you just pour on I doubt if one exists that would penetrate to any depth and it would dilute rapidly in the water. (Hydrochloric acid would dissolve limestone for example)
There are underwater hydraulic hammers that could break up the rock. They are usually fitted to a hydraulic excavator.
With some more details of the problem, more detailed suggestions are possible.

I would expect the operation to be very time consuming.

Check with the major dredge manufacturers - they have most likely addressed this in the past and can recommend cutter heads and procedures.
Keep the wheels on the ground

There is a milling head that can be attached to an excavator.
What volume of rock do you need to remove?
