Applications in the construction industry
.jpg)
The MULTITRACK NW range of thermally bonded non woven geotextiles have been developed for separation and filtration in a wide range of groundworks applications.
Manufactured using a unique thermal bonding process, our NW range has excellent filtration properties, making them ideal for use in a variety of construction applications. Examples would include trench drains, wrapping of attenuation units, wrapping of perforated drainage pipes, encapsulation of granular drainage blankets.
MULTITRACK 1000 is one of the UK’s most commonly specified general purpose non-woven geotextiles and is our alternative to Terram® 1000. Used as a separation and filtration layer in applications for erosion control, attenuation units, horse arenas, trench drains etc.
Multitrack has excellent filtration properties
Our Superior Non Woven (SNW) range of geotextiles are manufactured by needle punching a web of high tenacity fibres to produce a consistent & uniform product of highest performance.
Produced on state of the art computer controlled production lines, available in weights from 120 to 800gsm. SNW products offer excellent puncture resistance properties combined with high permeability, properties that provide engineers with a versatile fabric ideally suited for the protection and/or separation/filtration functions.
- Applications
Typical applications for Multitrack SNW range:
- Protection Fleece for impermeable liners
- SUDS
- Land fill sites
- Protecting coastal defences from erosion
- Pipeline protection fleece
- River bank erosion control

Multitrack SNW has high puncture resistance |
MULTITRACK Non-Woven geotextiles provide engineers with a comprehensive range of products 70-2000gsm.
They are manufactured in state of the art facilities and provide the combined qualities of high water permeability and mechanical robustness.They play a major role in construction when performing the functions of separation, filtration and erosion control.
Wrekin offer three main types of MULTITRACK non-woven geotextiles, using two manufacturing processes, thermal bonding and needle punching.
MULTITRACK non-woven geotextiles have been designed and developed to offer optimum performance per unit weight. Their resulting mechanical robustness and excellent hydraulic properties make them the ideal choice for applications requiring separation & filtration. Non-woven geotextiles, due to there high elongation at break, offer greater resistance to installation damage.
Furthermore non-woven geotextiles and in particular our SNW range, are ideally suited for use in membrane protection and coastal defenses due to there excellent puncture resistance and permeability properties.
Our Multitrack ranges have been carefully developed to provide engineers with a comprehensive choice of strengths, mechanical and hydraulic properties, to meet most on site requirements.
Multitrack has excellent filtration properties
Our Geotextiles are needlepunched fabrics made from Polyester or Polypropylene fibers. The fibers are needlepunched to form a stable, strong and flexible fabric with high water permeability and optimal pore size.
Our geotextiles range from 100gsm to 600gsm in white / black colour. Geotextile fabrics are used in separation, filtration, protection and subsurface drainage.

Description:
nonwoven geotextiles are manufactured from the extrusion of polypropylene fibres which are then laid down on a manufacturing "bed" and then needle punched to entangle the fibres such that a dimensionally stable product is formed. Some additional thermal treatment is then applied to further improve the strength of the geotextile.
