Remote & Difficult Access Repairs

Steep slope soil stabilization is a critical aspect of geotechnical engineering, particularly for pipeline sites that are located in mountainous or hilly terrain. When slopes are steep, soil stability can be compromised, leading to potential landslides, soil erosion, and other geohazards. To stabilize steep slopes, there are several engineered solutions that can be used, including:

• Soil nailing: Soil nailing involves drilling steel reinforcing bars (nails) into the slope at an angle and grouting them in place. This provides additional support to the soil, increasing its stability.
• Rock bolts: Rock bolts are similar to soil nails but are used in rock formations to stabilize slopes. They can be installed using a variety of drilling techniques, such as percussion drilling or diamond core drilling.
• Geogrids: Geogrids are synthetic materials that are installed horizontally across the slope and anchored into the soil. They act as a reinforcing layer, providing additional stability to the slope.
• Retaining walls: Retaining walls can be used to stabilize slopes by providing a vertical barrier to prevent soil movement. They can be made of concrete, stone, or other materials.
• Slope drainage: Proper drainage is critical to maintaining soil stability on steep slopes. Drainage systems, such as surface channels, subsurface drains, and culverts, can be installed to prevent water from accumulating on the slope and causing erosion or landslides.

When designing a steep slope stabilization solution, GeoStabilization International considers a variety of factors, such as soil type, slope angle, and groundwater conditions. By using appropriate engineering solutions, pipeline companies can mitigate the risks associated with steep slopes and ensure that their operations are safe and sustainable.
