Needle punched nonwoven geotextile for separation and filtration
Tipptex BS & NS nonwovens are a range of needle punched and thermally bonded geotextiles that offer the highest levels of engineering performance and quality standards. The thermal treated nonwoven range is used in various applications including site access roads, hard standings, road and railways, drainage blankets and car parks.
The hydraulic properties of Tipptex BS & NS nonwovens stimulate the build-up of a natural soil filter in the adjoining soil to ensure long term filtration stability.
The thermal treated nonwoven geotextiles lend valuable qualities to numerous groundwork construction applications. In railtrack maintenance for example, the thermal treated nonwoven minimises potential track failure which can be caused by pumping (ie the upward movement of fine particles from the underlying formation into the ballast)
