Multi-sock Filter

Permeable Knitted Polyester Filter Sleeve.

Multi-sock is a proven and tested permeable knitted polyester filter sleeve designed to fit over perforated round pipe to prevent the ingress of sandy soils and fine gravel into the pipe. Multi-sock helps establish a gradational filter system around the pipe and can be supplied either preloaded onto cardboard cores for expedient fitting to the pipe or supplied in rolls.
