GPS Non-woven Geotextile 20oz is made using needle punched nonwoven 100% polypropylene fibers. These fibers create dimensional stability, because they are woven into a completely random structure. The polypropylene fibers are resistant to the UV damage of the sun, will not rot, decay, degrade, nor are they affected by naturally occurring basics or acids. Polypropylene functions beautifully in a wide pH range: 2-13.
The 20 oz filter fabric is a strong heavy weight nonwoven geotextile. With a tensile strength of 425 pounds, it can provide sediment control on hillsides and riverbanks. It is great for filtering and commonly used in french drain systems.
