C O N S T RConstructing withFibertex GeotextilesFibertex offers a full range of nonwoven geotextilesdesigned for use in many different foundationstructures within civil engineering works. Themost common applications are:• Road works• Construction works• Ground systems• Drainage and filtration systems• Hydraulic works• Waste disposals (landfills)Fibertex technologyFibertex manufactures nonwoven geotextilesusing the drylaid needlepunch technology. Virginpolypropylene fibres are extruded, carded andfinally needlepunched. Furthermore, manyproduct types have thermal treatment added(e.g. IR bonding, hot air bonding or calendaring).Superior 3-dimensional geotextileFibertex Geotextiles are unique due to acombination of intensive needling and variousbonding processes. After being laid out horizontallythe intensive needling ensures that the fibres arefixed vertically. The result is a strong and flexible3-dimensional product which is advantageous inall parameters related to geotextiles.High performance FibertexGeotextilesThe drylaid needlepunch technology ensures highquality geotextiles with:• High strength and high elongation= high energy absoption• Excellent resistance to installation damage= high puncture resistance• Long-term wearing properties= more than 25 years of service life• Unique hydraulic properties= controlled high water flow• Excellent abrasion properties= no surface abrasion• High uniformity= ensured by production technique and qualitycontrol• No delamination= fibres interlocked in all 3 dimensionsAll Fibertex Geotextiles are UV-stabilised, resistantto acids and alkalis, and cannot be attacked byfungi or rot. No chemical binders are used inthe product or in the production process, andpolypropylene is a polymer material which turnsinto carbon dioxide and water vapour whenincinerated - both completely harmless substances.Advantages of using FibertexgeotextilesMore than 100 punches per cm 2Machine directionWhen using geotextiles between differentconstruction layers, mixing of the layers is avoided,resulting in an increase of bearing capacity andthereby also time and material savings. Highwater flow and good filter properties combinedwith the necessary mechanical properties of thegeotextile ensure that fine-grained particles areretained, while free movement of water is maintained.Consequently, stability is improved and life of theentire construction is prolonged.2
