FilterPlus™

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.

Nonwoven 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 nonwoven 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.
