    I've got to "push" a couple of 3/4" conduits under an existing concrete patio slab. Distance is about eight(8) feet. Patio was (reportedly) poured over a layer of compacted coarse sand. There is clear access from both ends. I've used a pressure washer to do this job under sidewalks, but never for such a distance. Can anyone offer some advice?
