Wrekin Non-Woven Geo Multitrack 1000 4.5mx100m GTNW/MULTITRACK
MultiTrack Non Woven (NW) is a range of thermally bonded non woven geotextiles which have been developed for separation and filtration in a wide range of groundworks applications.
The MultiTrack Non Woven range has excellent filtration properties, making them ideal for use in a variety of construction applications, including trench drains, wrapping of attenuation units, wrapping of perforated drainage pipes, encapsulation of granular drainage blankets and more.
MultiTrack 1000 is one of the UK’s most commonly specified general purpose non-woven geotextiles.
| Roll width | 4.5m |
| Roll length | 100m |
| Roll diameter | 29cm |
Applications
- Separating/strengthening layer under access roads and areas of hard-standing
- Filter surround for trench drains
- Separation to stop the intermixing of dissimilar soil layers
- Filtration, allowing the flow of water whilst preventing the passage of soil
The geotextile should be rolled out and allowed to follow the contours of the land. It should be kept as taut as possible in an effort to minimise folds but not stretched so that it spans over any hollows. Small deposits of fill material may be required across the geotextile to temporarily hold it in place until fill placement commences, if, for example, it is windy or the site is exposed. Fill may then be back tipped onto the geotextile and then spread out and compacted to the required depths. NO vehicle should traffic directly on the geotextile surface at any time.
In some instances it may be necessary to install geotextile in a hydraulic application and as polypropylene has a density less than 1, it will float. However, there are a number of measures that can be taken to enable installation in water, such as attaching steel rebar to make the product sink. In certain applications the use of divers may be required or it may be possible to work within the tidal window.
