A landslide occurs when the driving forces on a soil mass exceed the internal resisting forces of that soil mass and the land starts to move. Schnabel’s landslide repair methods utilize proven techniques to stop or prevent a landslide, whether it’s installing tieback anchors, soldier piles, and/or micropiles to provide additional external resisting force.
Tieback anchors provide the most positive and cost-effective landslide repair solution in many circumstances. If the site cannot accommodate mass excavation, or if the soil along the failure surface is difficult to drain, tieback anchors may be the only practical solution. At other times, tiebacks in combination with one or more other methods may work best.
Tieback walls constructed to control landslides are designed to increase the resisting forces to a predetermined factor of safety. The wall can be located within the slope to provide the resisting forces in an optimal direction. They can also be installed with minimal site disturbance.
