HORIZONTAL DRILLING with casing and down-hole hammer is an emerging technology in non-dig industry. It gives a solution for drilling on-line and on-grade holes under roads and buildings without disturbing the constructions at the ground surface.
Good Concept,, But where does the excavated materials go? the soil recovered might pile up at your drilling machine,,,, the spiral blades will push back the drilled soil and might pile up in your Drilling Machine,,, The spiral blades might also damage the surface of the internal pipe,
