I need to remove a strip of caliche about forty feet long, eight feet wide, and in thickness from zero to 12 inches. I have some ideas on how to go about this, but would like to hear from anyone who has worked with caliche before.
My ideas are: jackhammer with a spade bit, or drilling honeycombs with a star drill on a rotohammer to a standard plane of depth, and then breaking the honeycombs off. A layer of sand, then a layer of pavers will be put over the remaining caliche.
I had my brother in law try ripping it with claws on the back of his backhoe, but the stuff is too tough.
Ideas appreciated.
