Gabion Wall Repair

Gabion Wall Repair

A gabion basket retaining wall at the base of the famous resort’s gondola began to fail; causing a landslide that crept up the slope to the base of a critical tower foundation. Within a matter of days, GeoStabilization International®’s engineers assessed the situation and designed a repair that would stabilize the wall, prevent regression of the slide, and protect the tower’s foundation. The plan required GeoStabilization’s crews to install a dense array of Self-drilling SuperNails® into the baskets and then face the nail array with high-capacity Galfan® coated steel mesh and plates. The plates were then post-tensioned, allowing the nail array and mesh facing to actively arrest movement of the basket wall. Due to the limited access nature of the site, all the nails were drilled with GSI®’s purpose-built SuperNailer drill rig.

The design and construction of the repair took less than two weeks. By stabilizing the wall in-place, environmental disturbance was minimal and the cost of the repair was a fraction of more traditional repair techniques.
