I am taking a panel out of a large ground level water tank (*)that is assembled from pressed steel panels 1/4" thick. It was obviously bolted together on a concrete base then concrete added inside and out to seal the bottom of the panels - it's probably 50 or so years old.
So far I've oxy -acet cut off all the large bolts (36 of them!) and was hoping to run an angle grinder along the base line to make a point of weakness then just fatigue it off at ground level. No such luck - many 9" disks later I'm making little progress and it's winning the battle. I then tried oxy cutting but the concrete exfoliates and flys in your face. Any suggestions?
I wondered if laying a thin steel sheet on the concrete and running the torch along it might be a way forward but would welcome ideas from the forum.
