SELH05003 HydroWMS Permafilter Geotextile
Design
Permafilter Geotextile is a non-woven, dimpled, needle punched Geotextile that has been specifically designed for hydrocarbon pollution treatment in SUDS and other civil engineering applications.
- Drainage
- Reinforcement
- Filtration
- Can enhance water quality when used as part of a source control Sustainable Drainage System and eliminate the need for end of line petrol/oil interceptors

Applications
Charcon 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. Refer to SUDS technical services for advice on specific applications
Manufacturing standard
All products manufactured by Aggregate Industries are produced in accordance with ISO 9001 with factory compliance to ISO 14001.
Performance
The dimpled Geotextile comprises a proprietary 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. HydrowWMS Permafilter Geotextile is capable of retaining oil contamination ranging from daily car drip losses up to catastrophic spillages, i.e. originating from car oil-sump failures. The entrapped hydrocarbons are biodegraded by naturally occurring micro-organisms providing a self cleansing mechanism.
