A rocket hammer punches a hole, gravel is added, and the hammer compacts it, displacing and consolidating surrounding soft soil to form dense gravel piles. The pile tops are recompacted. This replaces reclaimed soil and densifies surrounding soil through the hammer's impact energy. | GIGadgets | Facebook
