Non-woven geotextile HaTe®

synthetic fiberfor erosion controlprotection

Separation, protection, filtration and drainage - with weights ranging between 150 g/m2 and 3,000 g/m2. The properties of HaTe nonwovens are tailored to your particular application. The first step involves the selection of a suitable raw material from a comprehensive range of synthetic staple fibres, which are mechanically bonded by needle-punching. Special fibre mixes producing low-flammability nonwovens are, for example, used on tunnel projects. Depending on requirements, HaTe nonwovens are manufactured in Geotextile Robustness Classes 1-5 to "M Geok E" ("Guidance Paper on the Use of Geosynthetics in Earthworks for Roadbuilding Projects"), issued by the FGSV (German Road and Transportation Research Association). For landfill construction, HaTe reinforced nonwovens are specially manufactured for the protection of thermoplastic liners. The composite product comprises a high-density, mechanically consolidated nonwoven reinforced by a woven layer. Reinforced nonwovens are manufactured in weights between 1,000 g/m2 and 3,000 g/m2. Other functions performed by HaTe nonwovens, particularly at landfill sites, include drainage, separation and gas removal. HaTe nonwovens can be customised to the specific requirements of your projects.
