Nonwoven geotextiles are generally categorized as light weight, medium weight, and heavy weight, indicating the thickness of the fabric, strength, and drainage capabilities. For example, light weight nonwoven geotextile fabric is more permeable and has high flow through rates. However, it isn’t as rugged as heavier weight fabric. Heavy weight non woven geotextile fabric has a slower drainage rate, but greater strength and provides increased support for soil stabilization.
