FILTERSOK® is a tough, tubular, one piece circular knitted polyester fabric for use with perforated drainage pipe.

FILTERSOK® bridges the perforations helping to stabilise the soil so sediment does not flow in and plug the drain line. Some of the very fine particles (colloidal particles) pass through and out of the drain lines with the water.

This is desirable since the removal of fine particles from the soil increases the permeability of the soil near the drain lines. FILTERSOK® is manufactured to State Highway Department specifications to achieve high abrasion resistance and durability.
