NAUE Nail system for reinforced slopes up to 60°

The NAUE Nail system for reinforced slopes combines the strength and durability of Secugrid® geogrids with soil nails to create a steep slope reinforcement system at slope inclinations up to 60°.

Secugrid®, with its uniform, flat bar construction and outstanding junction strength, provides the primary reinforcement in the slope direction. The dimensioned soil nails are spaced uniformly across the installed Secugrid® reinforcement, which covers the slope surface. Additionally, the Secumat® erosion control mat is placed over the Secugrid® soil reinforcement before the soil nails are secured. The topsoil-filled Secumat® promotes the establishment of vegetation for green walls and slopes. Vegetation can be established quickly and effectively with hydroseeding, where needed or preferred.

The NAUE Nail system can provide temporary or permanent steep slope reinforcement. It is characterised by a high degree of flexibility, allowing for significant adaptation to project-specific requirements, site layouts and conditions while still providing a high-strength yet economical slope-reinforcement solution with natural, long-term vegetation cover.

Secugrid® soil reinforcement geogrids are designed to accommodate various site conditions and available soil materials, including the ability to meet the challenges of a wide-range of native soil conditions – thus reducing the need for special, costly fill.
