Chips of polyester are spun, laid as a filament web and needle-punched into the sheet. Fibers sit in a three-dimensional arrangement rather than a woven yarn pattern.
The brochure describes strength together with in-plane drainage in both directions, elongation, a wide and tortuous pore range, and resistance to biological attack, acids, alkalis and ageing.
What the brochure emphasises
- Filtration and separation under embankments, revetments and channels.
- Separation, filtration and drainage under roads, railways and runways.
- Reinforcement and drainage at slopes, retaining walls and pavements.
- Soft-ground treatment, beach reclamation, and drainage or reinforcement at quays and breakwaters.
Uses named in the brochure
- Hydraulic embankments and slope protection.
- Channels: separation, and seepage control where the design asks for it.
- Roads, railways and airfields.
- Ports and coastal reclamation.
Stated in the brochure
- The brochure says polyester filament geotextile is already common in infrastructure and is being used more widely.
