In about 1973 we put a 32 foot x 24 foot addition on the existing house we bought. The addition called for a 4' deep foundation making the house when the addition was done a split level building. This was done because we knew that the ledge removal would be a challenge.
The ledge was soft materials for the most part with thin vanes of titanium going through roughly horizontal with the land. The ledge would break with the use of jack hammers until you hit the titanium vane then the steel (bits for the jack hammer or hoe ram) we used for breaking the ledge would mushroom over dulling the tool and a new steel had to be installed in the breaker.
After dulling a few steels we decided that we had to find a better way of doing the ledge removal, so the operator of the excavator had me go to his shop and pick up a hook that was used on the end of the excavator boom instead of a bucket and we used that to get under the titanium and break the soft ledge that worked good where there was large vanes of soft rock but were the soft rock vanes were thin we still had to use the jack hammer with steels to remove that, going between the titanium layers removing the soft rock.
Since I did the work at my house new equipment has evolved for removing ledge without blasting. A hoe ram was invented that hooked onto a excavator instead of a bucket. The hammer head is a couple of tons and has a steel on it similar to a jack hammer that can be used for breaking the ledge. The first hoe rams were air operated so you needed a large compressor to operate that hammer with large hoses. This unit was very cumbersome, so not good to use on small projects.
