Supply of Geo Bags Type-B (Size 2.00m x 1.50m)( pillow Type) 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) ≥300 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. It should resist UV degradation, rotting and alkalis.  Weight (ISO-9864/ASTMD 5261) ≥250 Gms/Sqm.  Tensile strength(MD) ( ASTMD 4595) = ≥12 kN/m  Tensile strength(CD) ( ASTMD 4595) = ≥12 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 (Bags are to be supplied of 100 numbers or part in a bundle, properly packed with name of Manufacturer and Batch Number is to be marked on each bag with “WRD Govt of ASSAM” to be printed on each bag and mentioning properly the GSM and type of Geo bag polymer. Test Certificate from approved NABL accredited and ISO Certified Laboratory should invariably be submitted against each batch of material). FOR GUWAHATI
