Hydraulic engineering nonwoven geotextile: Secutex® H
Secutex® H nonwoven geotextile for hydraulic engineering
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.
Typical solutions with Secutex® H
- Long-term filter efficiency
- High puncture resistance
- Long-term abrasion resistance
- Prevention of soil replacement
- 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
- Time and cost-saving installation
- Excellent long-term filter efficiency
- High robustness
- Long-term multi-directional internal shear strength
Advantages of Secutex® H
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.
Long-term filter efficiency
Secutex® H offers long-term filter efficiency in combination with high robustness properties, like abrasion resistance and resistance
to dynamic perforation loads.
Secutex® H nonwoven filter geotextiles and Secutex® HB sand mats provide an excellent stress-strain behaviour and adapt very well
to soil deformations or settlements. In the case of deformation, the nonwoven geotextiles stretch and adapt to the changed surface.
Contact erosion resulting from the direct contact between the geotextile, subsoil and the ballast layer can be prevented.
Secutex® H and Secutex® HB have been certified by the BAW (Federal Waterways Engineering and Research Institute) in Germany. Both
products meet the requirements according to the “Technical delivery conditions for geotextiles and geotextile-related products on
inland waterways” – 2018 edition of the Federal Ministry of Transport and Digital Infrastructure, and can be used accordingly for all
application conditions defined therein.
The use of Secutex® H nonwovens or Secutex® HB sand mats as filter layer in revetments can result in significant relief of work in
combination with cost savings. Due to the very low thickness, the material can be installed without further excavation. This results in
reduced construction time and less transport and construction costs compared to mineral grain filter layers.
Geosynthetics can replace the use of conventional building materials such as gravel, sand, etc. This means that less soil has to be
transported and therefore less CO2 is produced. This leads to a positive carbon footprint as already during the production and life cycle
of these geosynthetics only little CO2 is emitted.
