Linflex Fin and Narrow Filter Drains

Linflex Fin and Narrow Filter Drains provide drainage for both surface and sub-surface water. For applications where sub-surface only drainage is required, e.g. low capacity drainage for keeping water out of road structures, Fin and Narrow Filter drains may be used as an alternative. These products are for use in edge-of-pavement drains for the collection and/or disposal of sub-surface water in accordance with the requirements of Highways England.
