Supply of Geo-textile bags of Type-B (Size 2.00m x 1.50m), inner dimension made of composite layers of geo-textile as per specifications below : Woven Geo-textile for the outer cover. The woven geo textile is woven with UV resistant slit film tape fibre with MAVR values of the following properties. Geo-textile used to manufacture geo-textile bags should have high mechanical properties for enhanced durability along with enhanced puncture, abrasion and U.V. resistance characteristics. Geo-textile should be inert to biological degradation and resistant to naturally encountered chemicals, alkalis, and acids.  Weight (ISO-9864/ASTMD 5261) ≥250 Gms/Sqm.  Tensile strength(MD) ( ASTMD 4595) ≥35 KN/m  Tensile strength(CD) ( ASTMD 4595) ≥35 KN/m  Tensile Elongation ( ASTMD 4595) ≥5% & ≤30%  Grab Elongation ( ASTMD 4632) ≥5% & ≤30%  Tensile strength ( ASTMD 4632) = 1.5 KN  UV resistance( ASTMD 4355) = 70%/500 hrs Non woven Geo-textile for the inner layer It is needle punched non woven geo-textile made of 100% polypropylene staple fibers which are formed into a random network for dimensional stability.
