Non-treated nonwoven
Tipptex Non-treated nonwoven is a range of needle punched nonwoven geotextiles optimally designed to offer greater thickness and elongations compared to standard needle-punched nonwovens. This makes them well suited for protection and drainage applications where a thick cushioning layer and high elongation are key requirements for the design.
Typical areas of use include the protection of valuable pipeline coatings during backfilling, as an erosion control layer under rock armour in coastal defence projects, and as a protective cushion layer in landfills and reservoirs. Due to its high thicknesses, the non-treated nonwoven geotextile will provide higher water flow in the plane values compared to standard needle-punched nonwoven geotextile, allowing it to also function as a drainage layer in some applications.
Technical details:

- Available in weights from 300 to 1500 g/m²
- Fabric thicknesses up to 10 mm
- CBR puncture values up to 20 kN
- Produced using 100% virgin polypropylene staple fibres
- Project specific dimensions are available on request
