Secugrid^® reinforcing geogrid products are commonly used to stabilize steep slope soil veneers. Secugrid^® geosynthetic products can be effectively used to help protect slopes from erosion and veneer failure.

Stability

It is common to design slopes as steep as possible to optimize land use. This can lead to a larger crest area or a reduction of the embankment area. If the frictional and strength characteristics of the soil cannot provide a stable structure, special reinforcing measures are required. Secugrid^® geogrids are an economical alternative to modifying the slope geometry. Made from extruded high strength monolithic flat polyester (PET) or polypropylene (PP) bars, Secugrid^® carries excess slope forces by reinforcing the soil structure. With the optimized Secugrid^® product design, the flat Secugrid^® bars have maximum interlocking with the surrounding soil. The junction stiffness and negligible product construction elongation of Secugrid^® allows immediate force absorption when confining stress is applied. Compared to other geosynthetic reinforcement products, Secugrid^® geogrids show a steeper increase in the force/elongation diagram. Higher stress absorption and lower product elongation result in more economical construction methods. Different national guidelines for slope stability calculations can be used. The NAUE GmbH & Co. KG Secugrid^® Design Manual also contains design and product selection guidelines for proper use of the Secugrid^® geogrid products. The PET and PP resin used in Secugrid^® provides excellent physical characteristics and helps to allow for more economical product selections. Secugrid^® can withstand higher long-term creep stresses than other polyolefine products due to the unique manufacturing process.
