KBI FLEXI™-TWALL DETAIL Materials Description: KBI FLEXI ® - TWALL is comprised of ¼” – 5/8” Wire and Fiber Free Recycled Passenger / Truck / Off the Road Tire (OTR ) granule, mixed with ¼” – 5/8” “Fractured Faced” rock bound together with a “Single Component Aromatic Urethane” which is moisture cured. Production Description: • The KBI FLEXI ® - TWALL is manufactured in a Ambient temperature setting with no compression characteristics. • It is mixed 50:50 by weight with (50 pounds Recycled Tire Rubber and Aggregate + 5pounds of “Single Component Aromatic Urethane”) • The KBI FLEXI ® - TWALL mixture is then poured into the KBI FLEXI ® - TWALL mold and allowed to cure naturally through the interaction of curing with ambient humidity and moisture levels. • The KBI FLEXI ® - TWALL mixture is then poured into the KBI FLEXI ® - TWALL mold and allowed to cure naturally through the interaction of curing with ambient humidity and moisture levels. Product `Features and Benefits` Description: • The KBI FLEXI ® - TWALL is designed for the release of Hydraulic Water pressures that can be released through the porous design of the materials used in the KBI FLEXI ® - TWALL has a porosity rate of 3000+ gallons per square foot per hour, and the whole structure is porous due to the 23% dynamic pore space that is created within the modulus of the materials. • It has no steel reinforcement therefore rusting of any steel rebar etc. is eliminated. • The KBI FLEXI ® - TWALL has a designed tie back `T` construction that forms an anchor into the embankment of the stabilized earth or aggregate. • The structure expands and contracts with freeze thaw conditions. • It naturally incubates a “Bio - Film Bacteria” within the pore space of the structure which can remove up to 86% of dissolve Nitrates and Ortho Phosphorous. • The KBI FLEXI ® - TWALL can come in various colors and can have structural patterns on the face of the KBI FLEXI ® - TWALL. 6 Flexi Process 2020
