Non-woven geotextile SECUTEX® H

synthetic fiberfor filtrationfor river banks

The single-layered, needle-punched geotextile is used for application as filter and separation layer. Secutex® HB is a multi-layered needle-punched staple fibre nonwoven filled with quartz sand, also called sand mat. It is used as filter and separation layer for underwater installation in hydraulic engineering applications. Filter geotextile in hydraulic engineering Secutex® H is placed between two layers of different granular materials if the coarser layer cannot retain a significant fraction of the finer-grained layer under the expected pore water flow. Long-term filter efficiency High puncture resistance Long-term abrasion resistance Prevention of soil replacement Separation geotextile below impermeable cover layer or on top of an impermeable supporting layer Secutex® H is used as separation geotextile to prevent an intermixing of two adjacent grain layers with different grain sizes. High robustness against puncture and long-term abrasion Adaptation to soil deformations due to their high elongation Excellent interface shear resistance Resistance to chemical and biological degradation Underwater installation of nonwoven geotextile filters The sand mat Secutex® HB is used as a filter layer for fast and easy underwater installation. Time and cost-saving installation Excellent long-term filter efficiency High robustness Long-term multi-directional internal shear strength Secutex® H is the choice for all hydraulic engineering applications where a filter layer and/or a separation layer between granular layers with different grain sizes are required.
