Anchor block slope stabilization remediates slopes or existing retaining walls using anchored reaction blocks.

Common uses

Excavation support
Temporary or permanent slope stabilization
Repair of damaged or failing retaining walls

Process

Anchored block slope stabilization consists of discrete, anchored concrete blocks placed in a pattern on a slope to increase slope stability. 

The block layout pattern is typically in rows across the slope or retaining wall. A stable borehole is executed to the right diameter and designed length, filled with cement grout, and then the anchor (strand or bar with free and bond length) is installed. Reaction blocks are either precast or cast-in-place around the anchor heads. Bearing plates are installed, and the anchors are tensioned against the blocks. The finished anchored reaction blocks resist the movement of the retained soil or wall.

Advantages

Cost-saving solution for landslide repair and slope stability control
Can be designed for permanent or temporary support
Crane-mounted equipment can reach even the most difficult access slopes
