High strength raschel knitted geogrids

Geogrids are good all-around materials used in the construction sector.

They are used to separate adjacent types of ground, remove solid components when used as filters, absorb liquids over a wide area, prevent soil erosion, and provide mechanical protection.

Undue erosion and sedimentation from land disturbing dealings have been linked to serious land and water management issues, which are a large concern to the county residents. Of course, one of the most common ways to prevent erosion is to plant vegetation. Plants act as protective shields that can lessen the impact of rainfall and loosen the soil. Good water drainage also helps reduce erosion because it diverts excessive watering.

In the United States, said a report by the U.S. Climate Change Science Program in January 2009, "rising sea levels are submerging low-lying lands, eroding beaches, converting wetlands to open water, exacerbating coastal flooding, and increasing the salinity of estuaries and freshwater aquifers

Erosion Control, and Nanotechnologies (NT)

Erosion Control Forum – Information on erosion control devices and resources Skip to content Abstract Nanotechnology (NT) The National Nanotechnology Initiative defines nanotechnology as understanding and controlling matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Introduction Nanotechnology offers the potential to effectively treat contaminants in situ, avoiding excavation or the need to pump contaminated water out of the ground. The process begins with nanoparticles being injected into a contaminated aquifer via an injection well. Role of Nanotechnology Nanotechnology plays a crucial role in improving wind turbine performance...

Erosion Control Forum – Information on erosion control devices and resources Skip to content Bioventing Description Bioventing is an in situ remediation technology that uses microorganisms to biodegrade organic constituents adsorbed on soils in the unsaturated zone. Bioventing enhances the activity of indigenous bacteria and simulates the natural in situ biodegradation of hydrocarbons in soil by inducing air or oxygen flow into the unsaturated zone and, if necessary, by adding nutrients. During bioventing, oxygen may be supplied through direct air injection into residual contamination in soil. Bioventing primarily assists in the degradation of adsorbed fuel residuals, but also assists in the degradation of volatile organic compounds (VOCs) as vapors move slowly through biologically active...

Geogrid

Erosion Control Forum – Information on erosion control devices and resources Skip to content A geogrid is geosynthetic material used to reinforce soils and similar materials. Soils pull apart under tension. Compared to soil, geogrids are strong in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case.[citation needed]. Geogrids are commonly made of polymer materials, such as polyester, polyvinyl alcohol, polyethylene or polypropylene. They may be woven or knitted from yarns, heat-welded from strips of material, or produced by punching a regular pattern of holes in sheets of material, then stretched into a grid.Geogrid is typically used for soil reinforcement applications such as retaining walls, steepened slopes, embankments, sub-grade stabilization, embankments over soft ...
