Permafilter Geotextile - Product code: PV23002
Permafilter Geotextile is a non-woven, dimpled, needle-punched geotextile 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 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-cleansing 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 is clean and debris free before installing Permavoid.
