Schnabel specializes in a wide range of measures and solutions for landslide stabilization, including tiedback permanent walls, discrete structural elements, soldier piles, secant piles, and advanced soil nail slope stabilization techniques.

As a leading Geostructural Design & Construction contractor, we possess the expertise to deliver effective landslide repair and control services tailored to your project’s unique needs and challenging environmental conditions.

Soil Nail Slope Stabilization Solutions

When the driving forces on a soil mass surpass its internal resisting forces, landslides can occur. At Schnabel, our landslide repair services employ proven techniques, such as tieback anchors, soldier piles, micropiles, and soil nailing, to provide additional external resisting force and prevent or halt landslides. Tieback anchors are particularly effective and cost-efficient in various scenarios, especially when mass excavation is unfeasible or soil drainage along the failure surface poses challenges.

Depending on the situation, a combination of tiebacks and other methods may yield optimal results. Our tieback walls, meticulously designed to enhance resisting forces to meet predetermined safety factors, can be strategically located within slopes, ensuring optimal resistance in the desired direction while minimizing site disturbance.

The tiebacks employed by Schnabel are securely anchored through the wall into competent soil or rock below the slope failure surface. In certain situations, tieback loads are directly distributed to the soil using discrete concrete elements instead of a wall. These walls or elements are often buried within the slope, and the slope is meticulously re-vegetated to restore it to its original condition.

With over half a century of experience, Schnabel excels in providing innovative and cost-effective landslide repair services, including advanced soil nail slope stabilization techniques. To learn more about our expertise in slope stabilization, contact our team today.


landslide control services

Provo Canyon

Schnabel installed 208 permanent anchors in a side hill cut in Provo, Utah to stabilize a potential landslide which could have been triggered by a cut for a new roadway alignment.

landslide control measures

Summit Senior Care Facility

Schnabel constructed a permanent tieback wall to stabilize a large landslide and allow the construction of the new Summit Senior Care Facility in San Ramon California.

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.
