I would like to convert the slab end of my log cottage to a mud room/laundry. Is it possible to drill down through the slab in the location of the utility sink AND, working in the crawl space, drill horizontal deep under the slab and have the 2 meet so I can feed supply and grey water drain pipes without busting up the slab & digging a deep narrow trench inside the house? I've seen some crazy things on This Old House that makes me think this might be possible. Anyone here ever done this or know of it being done?
The slab end is accessible from the outside so drilling with a large rig is a possibility.
