Geotextile Filter Fabric | AS140

Geotextile for drainage, filtration and soil separation

eSafety's AS140 Geotextile Filter Fabric 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.

The product is manufactured to Australian standards & ISO 9002 quality procedures. 

There is a very broad differentiation of geotextiles based on the manufacturing processes involved. eSafety Supplies can provide continuous filament or staple fibre geotextiles. Polymers offered are polypropylene or polyester.

Product Information

Geotextile Filter Fabric 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. Because of this manufacturing process non-woven geotextiles are generally best used in applications of drainage, filtration and protection.

Applications

Due to the manufacturing process and their permeable properties, Geotextile Filter Fabric are generally best used in applications of drainage, filtration and separation.

1. Drainage: Geotextile Filter Fabric will efficiently collect surplus water from structures, such as rainwater or surplus water, from the soil and discharge it.
2. Filtration: Geotextile Filter Fabric provide superior hydraulic flow and soil retention, which makes them well suited for filtration in subsurface drainage applications and under hard armour systems.
3. Separation: Geotextile Filter Fabric are used for paved and unpaved roads, where ground conditions have been compromised. As a separation layer, geotextiles can aid preventing the intermixing of dissimilar materials, add to the performance life of the road and reduce the overall thickness of the road section by requiring less aggregate during construction.
