Whether stabilizing slopes or repairing landslide damage, Schnabel’s team ensures effective, long-lasting solutions.
Landslide Stabilization & Repair Solutions
Landslides occur when the forces pushing a soil mass downhill exceed the natural resistance within the mass, causing the land to shift. Schnabel’s landslide stabilization & repair services offer a range of proven techniques to prevent or stop a landslide. This includes methods like tieback anchors, soldier piles, and micropiles, all designed to provide additional external resistance to movement.
In many cases, tieback anchors present the most reliable and cost-effective solution for landslide repair. When mass excavation is not feasible or if the soil along the failure surface is difficult to drain, tieback anchors become a highly practical option. In some situations, combining tiebacks with other techniques can offer the best result.
Tieback walls, constructed to stabilize landslides, work by enhancing the resisting forces within the slope, ensuring a calculated factor of safety. These walls can be positioned within the slope for optimal force direction, and are installed with minimal disruption to the site.
The tiebacks anchor through the wall into solid soil or rock beneath the failure surface. In some cases, the load from the tiebacks is transferred directly to the soil using discrete concrete elements, instead of a traditional wall. Often, these walls or elements are buried within the slope and then re-vegetated to restore the area’s natural appearance.
With over 50 years of experience, Schnabel offers innovative and cost-effective landslide stabilization & repair solutions. To learn more about how we can help, contact our team today.

Landslide Stabilization Case Studies
Gallatin County Landslide Repair | Warsaw, KY
The Kentucky Transportation Cabinet (KYTC) contracted Schnabel to reconstruct a 1.25-mile-long section of the U.S. 42 highway that has been prone to landslides. Schnabel successfully installed a tieback retaining wall to help stabilize the existing landslides, which allowed the highway to reopen five months ahead of schedule and just in time for Memorial Day weekend.
Cal-Poly Landslide Stabilization | San Luis Obispo, CA
In 2017, a landslide on the Cal-Poly San Luis Obispo Campus caused an evacuation of the Fremont Dorm. Schnabel designed and built the earth retention system used to stabilize the slide and served as the general contractor for the project. This project received the 2023 CalGeo Project of the Year Award and the 2023 APWA Public Works Project of the Year Award.
Schnabel constructed a permanent tieback wall to stabilize an old landslide so that previously unusable land could be used to construct a new senior care facility. Schnabel worked closely with design consultant Cotton, Shires and Associates to produce a design that would stabilize a large slide close to numerous fault lines. This required deep soldier piles and high capacity tiebacks up to 150-foot long.
