A question for the people who know such things: My land has about 8" of dirt over solid bedrock hillside. Is it possible to somehow bolt my house foundation to the rock? Maybe make holes- somehow (?) - in the bedrock, fill them with concrete, set in bolts, and then fasten the foundation (treated wood) to the bolts? Is this possible without fancy, expensive power tools and/or heavy equipment? Since there's so little soil and I don't have the money or inclination to deal with a bulldozer and lots of gravel, the building sites aren't going to be very levelable short of blasting rock out, so I'd rather work around the existing conditions if I can. The slope is not real steep, about 20 degrees at worst. Thanks in advance for your help.
