Greenflo® is a knitted filter sock designed to fit over perforated round drainage pipes used in road edge and subsoil drainage applications. Its primary purpose is to filter fine particles within the subsoil drain, thereby reducing sediment build-up in the drainage pipe.
Greenflo filter socks are often fitted to round drainage pipes that are used for roads, retaining walls, sports ovals, landscaping and DIY projects. They are made to conform to the RTA (Road Traffic Authority) QA Specification 3553.
Greenflo filter socks are also conveniently available in 100-metre roll or a in preloaded tube format so that the filter sock can be efficiently fitted over the round drainage pipe.

FUNCTION
Filtration
Geosynthetics can act as a filter by allowing water to move freely through while preventing the migration of fine particles. Often used to prevent soils from migrating into drainage aggregate or pipes while maintaining flow. Can also prevent soil erosion in coastal and riverbanks when used below loose stones or rocks and other material.
