DuraForce® AS Series Nonwoven Geotextile

DuraForce® AS series geotextile is manufactured and tested to exact quality standards and rated according to the NZTA F/7 specification for geotextiles.

There is an extensive range of geotextiles available. Due to the process by which they are manufactured, different performance capabilities can be achieved. 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.

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 allows for the use of nonwoven geotextiles in applications of drainage, filtration and protection.

Frequently Asked Questions

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.
