FiberMax Macro™ is a fiber reinforcement option for concrete that needs more than basic shrinkage control. It is designed for heavy-duty industrial and warehouse floors, as well as select pavement applications, where added toughness and durability can help the slab perform under repeated use. By distributing synthetic fibers throughout the mix in three dimensions, FiberMax Macro™ supports the coarse aggregate and helps strengthen the concrete across the full section.
That three-dimensional reinforcement is important because conventional welded wire fabric and rebar work along a plane, while fiber reinforcement reaches throughout the mix. This helps reduce segregation, lower bleeding, and limit surface defects and curling, all while improving the concrete’s long-term integrity. For project teams, that means a practical option that can support performance without adding unnecessary complexity in the field.
FiberMax Macro™ is engineered as a secondary reinforcement system that provides excellent plastic shrinkage control and reduced settlement cracking. This increases flexural toughness, shatter resistance, and abrasion resistance, which can help concrete stand up better to traffic and wear over time. Depending on the project, it may serve as an alternative to welded wire fabric, light gauge steel reinforcement, and some steel fiber applications when properly designed and dosed.
The product is also suited for projects where efficiency matters. FiberMax Macro™ can reduce costs and production time while improving crew safety, which makes it a practical fit for large floor placements and other demanding concrete work. It is a straightforward reinforcement choice for teams that need dependable results and a material that works well in real-world conditions.
When a slab needs reinforcement that supports durability and performance, FiberMax Macro™ can be a practical part of the specification. Our team can help you review the product details, discuss whether it fits your application, and support the next step in your project planning.

FiberMax Macro™ increases flexural toughness, shatter resistance, and abrasion resistance for demanding applications.
The fibers help reduce plastic shrinkage cracking and reduce settlement cracking when used as designed.
FiberMax Macro™ is excellent for industrial floors, warehouse floors, and some pavement applications.
Micro-fibers like FiberMax FI and MI control plastic shrinkage cracking during early curing. Macro-fibers like FiberMax MA provide structural post-crack load capacity and can replace traditional steel reinforcement in certain applications. They serve different purposes and can be used together when both early-age and hardened-state performance are needed.
FiberMax MA is batched directly into your concrete at the plant and delivered ready to place. Prairie Materials operates plants across Illinois, Indiana, and Wisconsin, so macro-fiber reinforcement is available wherever we deliver.
