Soil nailing is an earth retention technique using grouted tension-resisting steel or fibre glass reinforced nails and can be employed for permanent or temporary support.

Fully trained and experienced ground stabilisation crews are needed to correctly execute soil nailing projects. A collaboration of techniques and materials is required to evaluate the ground pressure and assessing which nails and materials are the most suitable for different types of terrain. Soil Nailing is a specialist technique for erosion control and stabilisation for slopes, construction areas, earth retention for excavations for buildings, tunnels, deep cuts, and repairs to existing structures.

How does soil nailing work?

Soil nailing penetrates the surface to stabilise the ground whilst  adding a sheet of environmentally safe material over the soft soil to provide strength and promote regrowth. Also ensuring any loose soil from eroding, preventing any further erosion which may hinder further construction projects.

GSS uses only the highest quality soil nails and utilises the latest technology and innovations on stabilisation projects for our clients. Detailed investigation and planning along with the latest technology, ensures every project provides a stable, long-term solution to even the most demanding sloping and unstable sites.

Soil nailing equipment is small enough that it can easily negotiate restricted access. For existing steep slopes, such as bluffs or existing retaining walls, the soil nails can be installed from crane-suspended working platforms. Soil nails can also be installed directly beneath existing structures adjacent to excavations. Care should be exercised when applying the system underneath an existing structure. GSS has used extensive 3D modeling to avoid conflicts between soil nails and other earth retention systems on complex projects that involve the use of multiple techniques, and to ensure the safety of buried utilities.
