Hello people, i am looking for partners who might be interested in a find. concrete slab of unknown depth was dug 5m below a suspected site. water is present 1m above the concrete structure +7feet wide, very hardstuff, chisel and sledgehammer barely made a dent. We are looking for chemical methods of breaking it down. 3" bronze of copper tubing (corroded) is stuck on the top, no idea what it it for. Any suggestions would be greatly appreciated.
