The geotextile for the tubes, anchor tubes, and the scour apron/pad shall be a woven monofilament or multifilament pervious sheet of polymeric yarn. Fibers used in the manufacture of the geotextile fabric shall consist of long-chain synthetic polymers composed of at least 85 percent by weight polyolefins, polyesters, or polyamides. Stabilizers and/or inhibitors shall be added to the base polymer if necessary to make the filaments resistant to deterioration by ultraviolet light, oxidation, and heat exposure. Reclaimed or recycled fibers (post-consumer) or polymer shall not be added to the formulation. Geotextiles shall be formed into a network such that the filaments or yarns retain dimensional stability relative to each other (including the filaments or yarns at the edges of the fabric).

Geotextile tubes shall be fabricated by sewing together standard sheets of high-strength, woven geotextile material to form a tubular shape or by weaving the material into a tube shape.
