FORTA-FERRO® - Fiber Reinforcement
is an easy-to-finish, color-blended fiber, made of 100% virgin copolymer/ propylene; consisting of a twisted bundle non-fibrillating monofilament and a fibrillating network fiber, yielding a high-performance concrete reinforcement system.
FORTA-FERRO® is used to reduce plastic and hardened concrete shrinkage, improve impact strength, increase fatigue resistance, and concrete toughness. This extra heavy-duty fiber offers maximum long-term durability, structural enhancements, and effective secondary/ temperature crack control by incorporating a truly unique synergistic fiber system of long length design.
FORTA-FERRO® is non-corrosive, non-magnetic, and 100% alkali-proof!

One of the first sizeable FORTA FERRO® projects in Alaska occurred in early May 2004. The Anchorage unit floor slab measured 120 feet x 70 feet, and contained a radiant heat component along with several central floor drainage units.
The 5” thick slab required 112 cubic yards of pumped-in-place concrete, and contained 7.5 lbs. of FORTA FERRO® structural synthetic fiber per cubic yard. To minimize future potential forklift/ joint deterioration, only one saw cut was installed, resulting in two 60 feet x 70 feet slab sections.
To date, the machine-trowelled floor remains essentially free of cracks and curling, and has been used as a local reference model as well as a site for technical seminars for specifiers, designers, and contractors on high-volume synthetic fibers.
