Drainage geotextiles

Drainage. Geotextiles collect liquids or gases and convey them towards an outlet. 

Fabrics perform one or more function in each installation generally there is one primary function. The five basic primary functions have been identified as separation, stabili2ation, reinforcement, filtration, and drainage. When the geotextile is impregnated with an impermeable material such as an asphaltic... 

A Geonet drainage layer can be chosen if the HELP model shows it to be more effective than sand in controlling leachate production and is comparable in cost. It is assumed that the HELP model predicts a 75 to 80% reduction in leachate production. A Geotextile layer would be laid on either side of the Geonet drain to prevent clogging. A minimum slope of 3% would be provided to meet state requirements. 

Geotextiles are the polymeric textile materials that are widely used in civil engineering to provide reinforcement, filtration, separation, drainage, erosion resistance and asphalt reinforcement. They take many forms nonwoven and woven textiles, grids, and openwork structures sandwiched between layers of nonwoven for lateral drainage. The principal... 

In separation, the primary function of the geotextile is to prevent intrusion of one material into another in order to prevent contamination of either material by the other. In the case of an aggregate being placed over a firm foundation soil, the purpose is to maintain the drainage integrity of the aggregate wall application is similar. In landfill application, the purpose is to prevent intrusion of waste material into the leachette collector system.
