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


Anchored block slope stabilization consists of discrete, anchored concrete blocks placed in a pattern on a slope to increase the 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) installed. Reaction blocks are either precast or cast-in-place around the anchor heads. Bearing plates are then installed and the anchors are tensioned against the blocks. The finished anchored reaction blocks resist the movement of the retained soil or wall.
