Application:

• temporary support system for sheet pile, diaphragm wall, and pile wall retaining structures
• tension elements against uplift of foundation structures.

The principle of the method is that sub-horizontal boreholes are drilled through the any retaining wall and aa high strength steel tendons are placed into the grouted borehole. After the post-grouting and hardening process the tendons are pre-stressed under engineering supervision ensuring that the retaining wall remains stable and very low displacement can occur.
