The geotextile drainage fabric 10 oz. non woven is the first of the heavy weights, the strongest and sturdiest of all the nonwoven geotextiles. Heavy weight geotextile drainage fabrics boast superior strength with a grab tensile rating of 250 lbs. but also are very durable and among the most resistant to tear damage. While the strength of the 10 oz. geotextile drainage fabric is on par with that of woven geotextiles, it has the added benefit of being able to provide filtration while being a more pliable and forgiving fabric. Lightweight and medium weight versions of non woven geotextile drainage fabrics are also available for less rigorous site conditions.
