MultiTrack™

Non woven geotextile range

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 two types of MultiTrack™ non woven geotextiles, using two manufacturing processes, thermal bonding and needle punching, these are NW and SNW.

Key features:

Separation – Prevents intermixing of dissimilar soil laye
Filtration – Allows passage of fluids whilst retaining soil particles

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 and 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.

Mini Rolls:

Thermally bonded Multitrack 1000 is also available in a range of mini-rolls and packs from stock. Ideal for use on small construction and landscaping contracts, Multitrack mini rolls provide contractors with a cost effective solution for small general purpose applications.

Non woven geotextiles provide excellent filtration properties
