UltraFiber 500®

As the only fiber that readily absorbs decorative colors for concrete and results in a smooth clean finish, UltraFiber 500® is the natural choice for architectural and decorative concrete. Solomon Colors is proud to offer this unique reinforcing fiber, particularly suited for the aesthetic appeal of decorative concrete while also providing the valuable performance benefits desired and appreciated by concrete producers, contractors, and owners alike. Because of its valuable performance enhancing attributes, like cement, water, and aggregate, UltraFiber 500 should be an essential constituent of all your concrete placements.

UltraFiber 500 Cellulose Microfiber Pellets, cement reinforcing fibres

Solomon UltraFiber 500® is cellulose fiber reinforcement for industrial, commercial, residential, architectural and decorative applications. It also provides an excellent alternative to traditional secondary reinforcement – improving durability, impact resistance, shatter resistance, and freeze/thaw resistance without compromising appearance or finishability.

What Is UltraFiber 500

Solomon UltraFiber 500 is the only alkaline resistant cellulose fiber reinforcement. It is perfect for commercial and residential slabs, composite metal decks, paving, pervious paving, curb and gutter, slip form, architectural and decorative, shotcrete, wall, and white topping applications. UltraFiber 500 cellulose fiber accepts color better than any other commercially available fiber.
UltraFiber 500 provides excellent secondary reinforcement, is safe and easy to use, and provides superior finishability. It can replace traditional secondary reinforcement while improving durability, impact resistance, shatter resistance, and freeze/thaw resistance. Bonding between rebar and cement paste is improved while concrete permeability and absorption are reduced. Unlike polypropylene fiber, UltraFiber 500 is invisible in concrete, does not ball, fuzz, or blemish. It yields an aesthetically perfect finish with no special finishing practices. Also, unlike polypropylene fiber, UltraFiber 500 is derived from renewable resources.
UltraFiber 500 has superb finishing quality, unsurpassed crack control, better hydration and bonding, is great for decorative and colored concrete, and utilizes an automated dispensing system.

UltraFiber 500 Natural Concrete Fiber


Not only does UltraFiber 500 improve concrete properties, it enhances and contributes to protection and management of our environment and natural resources. One-hundred percent of UltraFiber 500 cellulose fiber is sourced from responsibly and sustainably managed forests in which every tree harvested to manufacture UltraFiber 500 is replanted with, several more to replace it. Since trees absorb and convert carbon dioxide to oxygen and water, the resultant reduction in carbon dioxide levels actively reverses the destructive cycle of greenhouse gas production and a healthy environmental, ecosystems is enhanced by the use of these sustainable and beneficial resources in producing UltraFiber 500.

Strength & Durability

UltraFiber 500 offers significant mitigation protection from the phenomenon of unsightly destructive plastic shrinkage cracking that can be caused by uncontrollable ambient weather conditions. This, improves the concrete durability in many respects, including significantly mitigating vulnerability to the deleterious effects of freeze/ thaw deterioration.

Commercial Burnished Floor

Cellulose is hydrophilic. This means that, unlike polypropylene and other synthetic fibers, UltraFiber 500 absorbs water and improves concrete/hydration. This makes for stronger concrete with less internal micro-cracking.

Cellulose Microfiber
Alkali Resistance

UltraFiber 500 meets ASTM and ICC standards for alkali resistance. The UltraFiber 500 fibers will not deteriorate or lose strength when exposed to high alkali environments.


UltraFiber 500 is the only fiber for decorative concrete. With no balling or fuzzing, UltraFiber 500 will not affect the appearance of the concrete. UltraFiber 500 is the only fiber on the market that will accept color, making it ideal for colored concrete and stained concrete.

Concrete Reinforcement Fiber Used In Stamped Concrete


With an industry-unique automated dispenser, UltraFiber is the safe and efficient choice. The UltraFiber Automated Dispenser doses precise loadings of fiber directly into the mix, without workers manually handling sacks of fiber. Water-soluble 1 lb. and 1.5 lb. bags make manual dosing simple. 600 lb. super sacks are designed for Automated Dispenser maximum ease and efficiency.
