Stumbled on this video of a product called Dexpan. It's an expanding agent than can do some major damage to reinforced concrete structures.
I'm thinking it would be a good tool for the 18C's,, If you have a bridge or other concrete structure you wants to weaken or destroy, but don't want to make a lot of noise?
Or you are working a hearts-n-minds project in a populated area.
The basic process is to drill a hole pattern, mix & pore the Dexpan, wait 24 hours.
It's something that needs some time and planning. And some of the reviews would suggest it is not viable for rocks formations & boulders,, maybe.
