Filter Plus™ Geotextile

Filter Plus™ is a premium nonwoven geotextile filter fabric

Filter Plus is supplied in small roll sizes and is best suited for subsoil drainage, filtration and separation, by preventing the intermixing of aggregates and soils. Filter Plus is ideal for smaller site applications.

Non-woven needle-punched geotextiles are manufactured from the extrusion of polymer fibres which are then laid down on a manufacturing ‘bed’. They are then needle punched to entangle the threads, resulting in a permeable, yet dimensionally stable product. Additional thermal treatment is applied to improve the strength of the geotextile further.

Therefore, due to this manufacturing process non-woven geotextiles are best used in applications of drainage, filtration and protection.

Frequently Asked Questions

For filtration in sub-soil drains, when the drainage system is designed correctly the geotextile prevents soil particles from entering drainage systems but doesn’t restrict water flow. As a separation layer between two materials e.g. clay base and stone infill. This will prevent the two materials mixing which wastes expensive aggregate.

NB: Some applications will need specific design and higher grade materials such as the DuraForce AS range. We recommend any civil or drainage works are designed by a suitably qualified chartered engineer.

We do not recommend using weedmat in place of a geotextile. Weedmat will provide separation between two materials to some extent, however it is typically a light grade, therefore sharp stones used for base course and retaining walls will tend to rip this and render it useless.

The overlap requirement is dependent on the application. The minimum recommended overlap is typically 300 mm.
