The casing may well lengthen to The full depth or may terminate previously mentioned the bond zone, Together with the reinforcing bar continuing to the full depth.
In a lot of these piles, tension grouting is followed by tremie grouting. On completion of strain grouting, a global injection grouting is done via a pre-installed sleeve port pipe. This grouting shall be accomplished prior to the hardening of primary tremie grout.

The first grout is injected just after the principal grout has hardened in group “D” micropiles, which can be much like team “C” micropiles.
