Thumping or non directional boring is for work where short sidewalks, drive ways, or road crossings where open trenching would be prohibitive. This equipment is capable of distances of up to 50’ to 75’ in certain types of soils. Equipment works by open a small starter trench or pit and a small receiving, line and level the piece of equipment on your target and turn loose. Double check your start level and target alignment. When equipment reaches pit, new pipe or product will then be hooked to equipment and pull backwards into starting pit. Equipment is capable of pipe diameter of 2” – 4”.
