Socked Ag Line is a flexible, corrugated drainage pipe wrapped in a geotextile filter sock to help prevent fine soil and sediment from entering and blocking the pipe. It is commonly installed in trenches behind retaining walls, around foundations, and in areas prone to waterlogging to efficiently collect and redirect excess groundwater.

The filter sock improves the longevity and performance of the drainage system, while installation with clean drainage aggregate is still recommended for optimal water flow. Compatible joiners are available to extend the length as required.
