Our Soil Nails Installation service offers a proven and effective geotechnical solution for enhancing the stability and shear strength of soil slopes and excavations. This technique involves the systematic installation of high-strength steel bars, commonly known as soil nails, into the soil mass, followed by thorough grouting to create a reinforced composite material. The installed soil nails act as tensile reinforcement, effectively increasing the overall shear resistance of the soil and significantly improving its stability against potential failure mechanisms such as landslides, slope creep, and excavation collapse. Often implemented in conjunction with a shotcrete facing, soil nailing provides a robust and adaptable method for stabilizing a wide range of natural and man-made slopes.

The process begins with a detailed geotechnical investigation and stability analysis to determine the appropriate length, diameter, spacing, and inclination of the soil nails required to achieve the desired level of reinforcement. Our experienced drilling crews then utilize specialized drilling equipment to create boreholes into the soil slope or excavation face at the predetermined locations and angles. Once the boreholes are completed, high-strength steel bars, typically threaded for enhanced grout adhesion, are inserted into the boreholes. Subsequently, a cementitious grout is injected under pressure to fill the annulus between the steel bar and the surrounding soil. This grouting process ensures a strong bond and effectively transfers tensile forces from the soil mass to the steel reinforcement.

The integration of soil nails significantly increases the internal shear strength of the soil mass by providing resistance to tensile stresses that can lead to slope instability. This reinforcement mechanism creates a more cohesive and stable soil structure, capable of withstanding greater loads and resisting deformation. In many applications, a layer of shotcrete, a pneumatically applied concrete, is applied to the slope face after the installation of soil nail heads and bearing plates. This shotcrete facing provides surface protection against erosion and weathering, further enhances the stability of the slope by distributing loads, and creates a more aesthetically pleasing and uniform surface.

Our Soil Nails Installation service is particularly well-suited for stabilizing steep natural slopes, reinforcing cut slopes in highway or railway construction, providing support for retaining walls and other earth retention structures, and stabilizing excavations for building foundations or underground utilities. The versatility of the technique allows for application in a variety of soil types and challenging terrain conditions. Our skilled team of geotechnical engineers and experienced installation technicians ensures that every soil nail is installed to the highest standards of quality and safety, providing a reliable and long-lasting solution for slope and excavation stabilization.
