The NAUE NAIL system 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® 5/5 Q1 ES 601
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 characterized 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.
