Enka®-Tex nonwoven
Enka-Tex nonwovens are a range of needle-punched and thermally bonded geotextiles that offer the highest levels of engineering performance and quality standards. It incorporates products with superior puncture resistance compared with other needle punched nonwoven products of comparable weight. The range is used in various applications including site access roads, hard standings, road and railways, drainage blankets, car parks, landfills and coastal engineering.
Enka-Tex N nonwoven geotextiles lend valuable qualities to numerous groundwork construction applications. In railtrack maintenance for example, Enka-Tex N minimises potential track failure which can be caused by pumping (ie the upward movement of fines from the underlying formation into the ballast).
The hydraulic properties of Enka-Tex N nonwovens stimulate the build-up of a natural soil filter in the adjoining soil to ensure long term filtration stability.
The superior products within the range offer a perfect balance between a reduced thermal treatment and needlepunching providing more elongation without compromising the strength. They are the perfect choice for the protection of impermeable membranes in landfill and reservoir construction, as well as for coastal protection from erosion below rock and concrete defences.

Technical details
Enka-Tex nonwovens are a range of polypropylene needle punched and thermally bonded nonwoven staple fibre geotextiles.
• Thermally and non thermally bonded nonwovens available
• CBR puncture strengths from 1 to 18 kN
• Available in weights of 100 to 1,300 g/m2
• Uniform tensile strenghts in all directions throughout the rolls up to 80 kN/m
• Standard widths 5.25 (black nonwovens) or 5.0 and 5.5 m (white nonwovens)
• Special types available with higher weights, tensile strengths or widths
Some special types of Enka-Tex N are available, such as a product up to 12 mm thick with excellent puncture and abrasion resistance, which is used as a thick cushioning layer in drainage and protection applications
