Use & Purposes
Geotextiles have had a long history of use in filtration, drainage, separation and protection applications in a range of civil, coastal and environmental engineering structures. Geotextiles are a relatively inexpensive product, that when designed and installed correctly can replace traditional granular treatments with significant cost savings, both in aggregate quantities used and traditional labour costs to install such aggregate systems.
Geofirma® nonwoven geotextiles are polymer based products that are manufactured from a variety of processes. Generally the engineering application for the product will determine the most suitable type of geotextile that should be selected for use by the designer or contractor.
There is a very broad differentiation of geotextiles based on the manufacturing processes involved. Global Synthetics can provide continuous filament or staple fibre geotextiles. Polymers offered are polypropylene or polyester.
Geofirma® nonwoven geotextiles are manufactured from the extrusion of 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. Due to the manufacturing processes and that the geotextile product is highly needle, these non-woven geotextiles are generally best suited for a wide range of geotechnical applications involving drainage, filtration, protection and separation.
Benefits of Geofirma® Geotextile
The Geofirma® geotextile product range is quality certified in ISO accredited quality factories to the highest manufacturing standards for both local and international markets. The product is wrapped in a highly UV stable outer wrap such that the product may be left outside, onsite for later use provided the wrapper is not removed prior to deployment and use. For details on how to best store the Geofirma non geotextile contact your Global Synthetics representative.
The non woven geotextile is readily available in warehouses across Australia.
Global Synthetics offers the Geofirma® polyester continuous filament nonwoven geotextile in a range of weights, strengths and filtration characteristics for these engineering applications. Additionally, a number of roll widths and lengths are available across these grades to suit your application.
To best assist you in determining which Geofirma® non woven geofabric product is right for your application we have developed a ‘Technical Guide on the Selection and Specification of Global Synthetics Geotextiles for Transportation Applications’. This guide indicates, based on long term experience, the candidate geotextile that has generally proven suitable for use in specific environments associated with factors such as temperature, chemical, soils type, damage and ground conditions.
Global Synthetics can assist with additional advice regarding soil reinforcement under embankments, within slopes, over piles, wall design and pavement improvement, using additional specialist geosynthetic products, for such applications.
