Impact moling is a trenchless technique where a heavy mole or projectile is driven through the soil to create a bore path that cables can be pulled through. This approach is commonly described as missile bore, because a projectile (the missile) is launched through the ground to establish the passage, after which the cable or conduit is pulled back through the bore. The other methods listed—vibrotary plow, horizontal directional drilling, and rip plow—use different mechanisms: a vibrotary plow cuts and plows through soil with vibration, HDD drills a guided bore with a drill head, and a rip plow tears and plows the surface rather than creating a dedicated bore path with an impact tool.
