Earth-retaining Structures

The Cintec anchoring system provides a fast and efficient technique to stabilise earth-retaining structures. From centuries-old town walls to rail retaining walls—even in ancient ruins in Israel—Cintec’s ground anchoring system has provided adaptations for each project’s unique requirements whilst remaining sensitive to the original architecture.

In earth-retaining structures, ground anchors provide the main reinforcement; other anchors can also be used to provide additional consolidation.

The Cintec anchoring system for ground anchors is essentially the same concept. The first step is assessment to develop the most effective and efficient design, including the type of anchors to be used and where they should be installed. Investigative cores are taken to determine the wall thickness, type of material within the wall and the consistency of the retained material.

Once a design has been established, the system is ready for installation. A stainless steel reinforcement bar in is inserted into a fabric ‘sock’ and the entire assembly is inserted into a pre-drilled oversized hole. The sock is injected with Cintec’s cementitious Presstec™ grout, and the grout fills in the voids around the steel bar, efficiently fixing everything in place. The sock’s close weave permits small amounts of the grout milk, which is a cementitious bonding agent, to seep into the surrounding ground to further strengthen the fixing.

Unlike conventional mechanical anchors, the Cintec anchoring system benefits from fissures and voids—these are filled by the flexible grout-filled sock to create a strong mechanical bond.  Additional information can be found at http://www.earthretainingwalls.com.
