FiberMaxFI™ is a fibrillated polypropylene fiber reinforcement designed specifically for residential and light commercial flatwork. The unique fibrillated network with micro-fibrils creates superior bonding to the concrete matrix, preventing 80-100% of plastic shrinkage cracks while delivering excellent finishing characteristics.
FiberMaxFI™ employs fibrillated polypropylene fibers that generate additional micro-fibrils for more adhesion points with the mortar matrix. This three-dimensional network supports coarse aggregates, minimizes segregation and bleeding, and provides shrinkage and temperature reinforcement that precisely controls cracking when most cracks occur in the plastic state.
United Materials offers versatile delivery options to match your project needs. Choose the right truck for efficient aggregate placement.
Best for standard bulk deliveries like base stone, gravel fills, and driveways, where direct dumping works well.
Ideal for reaching elevated or obstructed areas, such as retaining walls, hardscapes, and site grading, with reduced double handling.
Perfect for precise, long-distance placement on large projects, bridge abutments, and tight access zones requiring accuracy and minimal site disruption.
Stops 80-100% of plastic shrinkage cracks—the most common early-age cracking mode.
Fibrillated fibers maintain excellent workability and surface appearance for smooth, professional results.
Replaces light gauge welded wire fabric (6x6 W1.4xW1.4) in residential driveways, patios, sidewalks, and garage floors.
FiberMaxFI™ is perfect for residential driveways, patios, sidewalks, garage floors, and light commercial slabs where plastic shrinkage control and smooth finishes matter.
Yes, FiberMaxFI™ complies with ASTM C1116/C1116M Section 4.1.3, Type III, Note 2 for synthetic fiber reinforcement.
FiberMaxFI™ is a cost-effective alternative to light gauge WWF (6×6 W1.4xW1.4) for shrinkage crack control in residential flatwork.
The fibrillated structure with micro-fibrils bonds tightly to the concrete matrix, creating tensile and compressive strength gains while preventing plastic cracks
United Materials supplies FiberMaxFI™ with precise fiber dosage and uniform dispersion for consistent performance in residential pours. Our dispatch team ensures timely delivery, so homeowners and contractors get reliable results when you need them.
FiberMaxFI™ mixes receive rigorous testing for fiber content, crack control efficacy, finish-ability, and compliance with ASTM specifications. United Materials’ quality controls deliver predictable performance for residential contractors.
Specify FiberMaxFI™ for driveways, patios, and slabs that stay smooth and crack-free. Contact United Materials to download the brochure, confirm WWF replacement options, or order FiberMaxFI™ for your next residential project.
