WIND ENERGY AND GEOSYNTHETICS WIND ENERGY

Secugrid® geogrids are produced with a new dimension of manufacturing technology. The reinforcement element is a highly-oriented polypropylene or polyester bar that is uniformly extruded and drawn to achieve a high modulus and high strength at low elongations. This is combined with the NAUE-patented welding technology to provide a structurally sound and stable geogrid. Secugrid® is used mainly for base reinforcement, mechanically stabilised earth (MSE) wall construction including veneer stabilisation, the segmental retaining wall (SRW) market, embankment reinforcement, load transfer...

Renewable Wind Energy Summary of Renewable Wind Energy and Geosynthetics From wind farms to biomass, methane conversion to hydro, geosynthetics are providing environmental protection and cost and operational efficiencies to help realize sustainable goals and responsible development around the world. Global new investment in renewable energy increased during 2008 to 2010 dramatically from USD $130 billion to $211 billion [1]. Wind energy is the fastest growing renewables sector, adding nearly 40 GW in 2010 alone. With leading adopters including India, China, Spain, Germany, the United...

Case Study: Whitelee Wind Farm, Eaglesham Moor, Scotland Situated just 17km outside of Scotland's second largest city, Glasgow, the 5.5ha Whitelee Wind Farm at Eaglesham Moor has emerged as one of the most important renewable power sites in the United Kingdom. With 140 turbines, the site is capable of providing 322MW, which is enough to power 180,000 homes. The geosynthetic reinforcement was imperative if these roads were to be realised and economical. In the construction, Secugrid® 40/40 Q1 geogrids were installed in the 600mm-thick separator layer at 200mm intervals (fig. 3). »Whatever...

Economics & Environmental Benefits Figure 5 Calculation diagram for crushed rock and gravel subbase unreinforced and Secugrid® reinforced Close to 40% of the world's energy consumption and greenhouse gas emissions are related to construction. This provides the construction industry an enormous opportunity to improve and provide more sustainable solutions. The NAUE group is committed to protecting the environment. Our manufacturing techniques and our engineering solutions are designed to provide economical and environmental benefits for our clients. With a Secugrid® 30/30 Q1 geogrid...

Secugrid® Secugrid® geogrids are manufactured from high-quality polypropylene (PP) or polyester (PET) bars which are welded firmly together, providing a structurally sound and stable geogrid. Highly orientated bars of Secugrid® that are uniformly extruded and drawn, enable high tensile strength at low strains. And the roughened surface of these individual bars increases frictional properties, which allows fine-grained materials to transfer loads to the Secugrid® reinforcement. This exceptional stress/strain behaviour at low elongation is vital to reinforcement success and long-term...

Combigrid® Reinforcement alone is not always enough. Additional engineering functions may be required in the reinforcement layer, such as separation, filtration and drainage. Combigrid® combines all of these requirements in a single product. This composite product combines a Secugrid® geogrid with a needlepunched Secutex® non-woven geotextile.
