Terrafix® 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, Terrafix® can be used in harbour basin protection; Terrafix® sand containers have been successfully used in coastal and river bank protection. Terrafix® has high water permeability, retains soil, and allows root growth so that bank protection structures will blend unobtrusively with the natural environment. Terrafix® provides scour protection for revetments, in waterways, around pillars and longitudinal and transverse hydraulic structures.
More than 30 years of successful Terrafix® 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. Terrafix® stands out for its flexibility, filter stability, and resistance to abrasion. Terrafix® 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. Terrafix®’s excellent sewn-seam properties minimise displacement of adjacent panels during installation and operation.
The easy and precise spreader bar installation means high efficiency. This adds up to significant economic savings when compared to conventional granular filters. Using Terrafix® makes the extraction, transport, and installation of high cost and labour-intensive sand and gravel filter layers unnecessary; Terrafix® may be covered directly with heavy armour stone. Its proven durability ensures long service lives of structures and minimises maintenance costs. The weather-proof and UV-resistant wrapping protects Terrafix® 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. Terrafix® is a high quality, robust and filter stable geosynthetic which has been used successfully throughout the world in hydraulic engineering for decades.
