The charge of concrete is then poured from the tube. The extraction with the tube plus the ramming of concrete is effected by the upward as well as downward blows of your hammer.

Through the downward blow, the concrete is compacted and rammed outwards therefore forming corrugated floor for your pile. This leads to greater friction between the pile area plus the surrounding ground.
