Abstract
Tubular geotextile fabric is mounted on a collapsible supply cartridge, which may be shipped to a perforated drain pipe manufacturer, distributor, or retailer in collapsed form to save shipping space. Upon receipt by the manufacturer or the others, the collapsible tube is reshaped to easily slide over the pipe. As the pipe pushes through the cartridge, the fabric becomes positioned thereon.
