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.
- Approved geotextile for filtration, separation, and drainage in convenient widths for all drainage applications
- Filter Plus is certified to meet Transit New Zealand F7 geotextile filtration requirements in all classes (1, 2, 3 & 4)
- Prevents soil particles from entering drainage systems while un-restricting water flows
- Assists conveyance of water along the plane of the geotextile to an outlet, either horizontally or vertically
