Permafilter Geotextile is a non-woven, dimpled, needle-punched geotextile membrane that has been specifically designed for hydrocarbon pollution treatment in sustainable drainage systems (SuDS) and other civil engineering applications.
Permafilter Geotextile is suitable for use in a range of applications including residential, industrial estates, swales, sports pitches, car parks, roofs, basements, pedestrian areas and rainwater harvesting.
The dimpled geotextile membrane comprises of a proprietary blend of polyester fibres with hydrophilic (water-attracting and oil repellent) and hydrophobic (oil attracting and water repellent) properties to achieve superior oil retention. Permafilter Geotextile is capable of retaining a range of oil contamination types, from daily car drip losses to catastrophic spillages such as car oil-slump failures. The entrapped hydrocarbons are biodegraded by naturally occurring microorganisms, providing a self-cleaning mechanism. Permafilter is capable of retaining 6l of oil per 10m².
Permafilter should be laid to suit site-specific requirements. Overlaps should be a minimum of 300mm or heat sealed. Ensure that the geotextile membrane is clean and debris free before installing Permavoid.
