About Filter Plus

Filter Plus, with its small roll size, it is generally used for subsoil drainage filtration and separation by preventing the intermixing of aggregates and soils in smaller applications.

Filter Plus is the small roll size range of DuraForce™ nonwoven geotextile.

Nonwoven needle punched geotextiles are manufactured from the extrusion of fibers which are then laid down on a manufacturing ‘bed’. They are then needle punched to entangle the fibers resulting in a porous yet dimensionally stable product. Additional thermal treatment is then applied to further improve the strength of the geotextile. Due to this manufacturing process, nonwoven geotextiles are generally best used in applications of drainage, filtration and protection.

Frequently Asked Questions

What are the main uses of Filter Plus?

Filter Plus is mainly used for filtration, separation and reinforcement. Needle punched is better for filtration and woven is better for reinforcement although both will effectively separate soil layers.

Is Filter Plus UV stable?

Filter Plus is tested for UV resistance, and achieves greater than 80% retained after 500 hours testing.

In reality this means the product is UV stable for the duration of exposure and working times, but it is not designed to be exposed for years.

Does the colour make any difference?

No. The grey and black fabrics have a pigment added, usually to hide imperfections in the raw material due to recycled material being used.

Filter Plus is made from 100% virgin polypropylene.
