Henry,
I thought that you might be interested in this video of a silo demolition that I did with All Metals Recycling. The property owners are having all of the barns removed & this 80 ft tall silo removed so that they can build a new home and sell a few building lots.
I am sure that it took a lot longer to erect this silo than it did to take it down. Less than 1 minute once the cable was connected. I have been told that many people know the blocks out with a sledge hammer and let the silo fall like a tree. Due to the extreme cost of worker’s compensation insurance, potential for death, ect.. we opt for the cable method.
The job went just as planned and today the crew is removing the concrete and cement silo staves.
