Permafilter Geotextile is a non-woven, dimpled, needle punched geotextile designed specifically for hydrocarbon pollution treatment in SUDS and civil engineering applications including residential estates, industrial estates, swales, sports pitches, car parks, roofs, basements, pedestrian areas and rainwater harvesting.
The dimpled surface comprises a blend of polyester fibres that incorporate hydrophilic (water attracting and oil repellent) and hydrophobic (oil attracting and water repellent) properties to achieve superior oil retention.
It provides drainage, filtration and reinforcement, as well as enhancing water quality when it is used as part of a source control sustainable drainage system, which eliminates the need for end of line petrol/oil interceptors.
Permafilter Geotextile is capable of retaining oil contamination ranging from daily car drip losses up to larger scale, potentially catastrophic spillages originating from car oil-sump failures. The entrapped hydrocarbons are biodegraded by naturally occurring micro-organisms providing a self cleansing mechanism.
