This air-driven system vibrates steel casings down to strata that give suitable resistance. Casings are welded in small sections on site to attain the required depth and subsequently filled with concrete and steel reinforcement. This rig can operate in very restricted headroom and limited access situations. This method of piling creates no spoil to remove from site.
