Ahead of hardening of the main grout, similar grout is injected after by way of a sleeve grout pipe in a stress of the nadir of 1.0MPa.

The steel casing is buried in soil or rock as well as the grout is forced into both equally finishes on the casing by using a counterweighted drill string. The grout is then crammed with cement in excess of the whole casing length.

Since smaller piles are a lot less in diameter they will be progressed through the base at an improved speed and may damage as a result of elements with far more substantial simplicity than a caisson casing or a pushed pile.
