FORTA FERRO-GREEN® is a unique blend of recycled polypropylene and copolymer macro fibers designed specifically for pervious concrete applications. The FORTA-GREEN blend consists of 100% recycled polypropylene fibrillated (network) fibers and a high-performance twisted-bundle macro-monofilament fiber, designed to mix, distribute, and finish well in pervious concrete mixes.
This fiber combination offers a variety of desirable benefits to pervious concrete pavement applications, including increased strength, toughness, freeze-thaw resistance, and durability.
FERRO-GREEN is used to toughen any pervious concrete application, such as driveways, curbs and sidewalks, and commercial parking lots and pavements. The three-dimensionally distributed non-corrosive macro fiber blend is one of the few methods available to add true toughness reinforcement to pervious cross-sections, without reducing porosity.
FERRO-GREEN also increases resistance to freeze-thaw damage and raveling, while preserving both the plastic and hardened concrete void structure.
FERRO-GREEN is generally dosed in a range of 0.17% to 0.5% by volume of concrete, or 2.5 lb. to 7.5 lb. per cubic yard of pervious concrete, depending on the desired level of additional toughness and crack-control required for the application.
