TITAN Injection Anchors
The heart of the system is the self-drilling TITAN micropiles, which can be used as a ground improvement measure. Ground improvement by way of the interlocking body of grout enables tension, compression and cyclic loads to be transferred to the in-situ soil. TITAN micropiles are covered by National Technical Approval Z-34.14-209 issued by the DIBt. This is the only tubular grouted pile system that can also be used for permanent applications of 100+ years.

1) The load-carrying capacities must be reduced according to National Technical Approval Z-34.14-209 in the case of permanent tension loads and cement grout cover c < 45 mm.
2) An approval for these sizes is not yet available. The values were interpolated in a similar way to the approval for TITAN 30/16, 73/56 and 127/103 micropiles.
3) A characteristic load carrying capacity Rk = 250 kN may be used for TITAN 30/11 in temporary installations.
4) Only applies to hollow steel tendon without coupling nut. The ultimate load is 2048 kN for coupled hollow steel tendons.
5) The values are to be used in the case of deformation calculations. These values were determined in tests. It is not possible to calculate the modulus of elasticity, cross-sectional area or moment of inertia from these figures.
