Hydraulic engineering geotextile Secutex® H

Secutex® H is a single-layer or multi-layer, needle-punched nonwoven hydraulic engineering geotextile. Secutex® H geotextiles are used as protection geotextile, separation geotextile, filter geotextile and geotextile for sand container and sand bag applications.

Secutex® H hydraulic engineering applications

  • Revetments
  • Groynes
  • Breakwater
  • Reefs
  • Dune protection
  • Scour protection and scour filling
  • Power plant channels
  • Dyke construction
  • Dam construction
  • Coastal protection
  • River bank protection

Advantages of Secutex® H

  • Excellent filtration properties
  • Long-term hydraulic performance
  • High elongation and therefore adjustable to soil deformations
  • Very good interface shear resistance
  • Resistance to chemical and biological degradation
  • High puncture resistance

Secutex® H the geotextile for hydraulic engineering applications

Secutex® H is a versatile material and is used for a wide range of functions including: single or multi-layered geotextile filters, sand ballast mats (sand mats), sand containers or tubes and scour protection. Secutex® H nonwovens and sand mats act as separators and filters in hydraulic engineering applications such as embankment construction, canal bed rehabilitation and protection, and coastal works.

Fabricated into tubes, Secutex® H can be used in harbour basin protection. Secutex® H sand containers and sand bags have been successfully used in coastal protection and river bank protection. Secutex® H geotextile have high water permeability, retain soil and allow root growth so that bank protection structures will blend unobtrusively with the natural environment. Secutex® H hydraulic engineering geotextile provides scour protection for revetments, in waterways, around pillars and longitudinal and transverse hydraulic structures.

This hydraulic engineering geotextile is safe

More than 40 years of successful Secutex® H nonwoven geotextile applications in hydraulic engineering are proof of our high technical standards and abilities. Tests carried out by the Federal Institute for Waterways Engineering (Bundesanstalt für Wasserbau, BAW), as well as continuous manufacturing and third-party quality control, affirm our commitment to high quality.

Secutex® H geotextiles stand out for their flexibility, filter stability, and resistance to abrasion. Secutex® H conforms to almost any installation surface and may even be covered directly with heavy armour stone. Our extra-wide rolls reduce the number of overlaps required to complete the job. The excellent sewn-seam properties of Secutex® H geotextiles minimise displacement of adjacent panels during installation and operation.

The economical hydraulic engineering geotextile Secutex® H

The easy and precise spreader bar installation means high efficiency. This adds up to significant economic savings when compared to conventional granular filters. Using Secutex® H makes the extraction, transport, and installation of high cost and labour-intensive sand and gravel filter layers unnecessary.

Secutex® H may be covered directly with heavy armour stone. Its proven durability ensures long service lives of structures and minimises maintenance costs.

Easy under water installation

The weather-proof and UV-resistant wrapping protects Secutex® H during transportation and on-site and it can be off-loaded and stored with little effort. To facilitate installation, the rolls may be cut on site with standard cutting devices. Installation of this geotextile on site and under water is easy.

High quality, robust and filter stable geosynthetic

Secutex® H hydraulic engineering geotextiles are a high quality, robust and filter stable geosynthetic which have been used successfully throughout the world in hydraulic engineering for decades.
