Emerging Technology in Fiber Reinforcement

Advancing reinforcement innovation with real-world impact

REGEN Fiber's E-Flex reinforcement fiber

FIBER REINFORCEMENT, REDEFINED

REGEN Fiber is engineered from the unique composite makeup of retired wind turbine blades, giving it a distinct performance profile that’s unlike any other fiber on the market.

Where traditional reinforcement fibers can fall short by either balling up, poking up from the surface, or falling to deliver performance gains, REGEN Fiber stands out by being easy to use, getting the job done faster, and producing field-proven results.

smarter material with real jobsite results

Our fibers are made from recycled wind turbine blades, a high-strength, industrial-grade composite material, designed to resist wear and tear through decades of extreme wind and weather. That high strength-to-weight ratio in its original life gives REGEN Fiber products continued strength and durability in its second life, with a more versatile internal structure than virgin plastic-based or steel alternatives.

This advanced composition supports:

Early strength and resilience gains
Smooth, clean finishing–fibers disappear in concrete without sticking up at the surface
Enhanced moisture control to help speed up concrete curing and shorten construction schedules

Beyond research and development, these benefits have been seen by contractors, and ready-mix partners, and concrete producers using REGEN Fiber in real-world applications.

Find the best fiber for your project

“You couldn’t tell the fibers were there after it was broomed, cured and saw cut. I definitely prefer using REGEN Fiber concrete fibers compared to steel fibers”

“I would definitely use REGEN Fiber’s [concrete reinforcement] fibers again, as they provide an environmentally friendly substitution for polypropylene fibers."

“We love the environmental story REGEN Fiber allows us to tell.”

The difference on-site

Experienced pros continue to tell us regen fiber can:

Finish cleaner, even with broomed surfaces
Prevent fibers being visible at the surface in final cured concrete
Help manage drying and shrinkage with observed improvements in curing timelines
Allow teams to pour and move on faster, providing cost-effective advancements in project design and flexibility

REGEN Fiber’s strength is in helping projects perform more efficiently without a compromise in durability.
