I met of a guy that went to Italy to research ancient concrete "secrets." 50 years later, two demolition businesses went broke trying to take down the concrete building he put up.
I guess those demolition businesses were experts in taking down house made of wood
Regular commercial demolition companies. The second company knew about the first one and I believe they had recently taken down an overpass with a significant amount of concrete. They beat on it with the biggest hand held jackhammers they had for a couple of days, then a jackhammer on a bobcat.
