DuraForce® AS Geotextile

DuraForce® AS geotextiles are manufactured and tested to exact quality standards and tested according to the Australian Standards for geotextiles.

There are a range of grades available depending on the application and the strength required. Due to the needle punching process by which they are made, the primary function of the DuraForce AS geotextiles is often filtration and separation, and other common uses include drainage and as a protection layer against membranes.

Frequently there will be a secondary function required of the geotextile as well as the primary function, e.g. drainage as the primary function and separation as the secondary function.

Nonwoven needle-punched geotextiles are manufactured from the extrusion of fibres which are laid down on a manufacturing ‘bed’ and then needle punched. This manufacturing process gives a stable engineered fabric suitable for a range of functions.



Frequently Asked Questions

  • Filtration, separation and reinforcement.
  • Needle punched is preferable for filtration, and woven is tougher for reinforcement.
  • Both will effectively separate soil layers.

Some geotextiles appear thinner than other brands for the same strength class owing to the manufacturing process. If the textile is needled punched further, to get effective interlock of the fibres, it can appear thinner for the same mass and strength. If a geotextile of the same weight appears thicker and fluffier the difference is probably only fresh air, and who wants to pay for fresh air?

As a separation layer between two matierials e.g clay base and GAP40. This will prevent the two materials mixing which wastes expensive aggregate.

For reinforcing/strengthening the ground. This will ensure your surface is more stable for years to come. Particularly useful with peat/unstable clay ground conditions.

For filtration as the geotextile allows the displacement of water across the relevant area.
