OVERVIEW
FORTA ULTRA-NET is used to reduce plastic and hardened concrete shrinkage, improve impact strength, increase fatigue resistance and concrete toughness. This extra heavy-duty fiber offers ULTRA-NETWORKING power, maximum long-term durability, and true secondary/temperature control by incorporating a fibrillated pattern and long length option. Non-corrosive, non-magnetic and 100% Alkali Proof!
FORTA ULTRA-NET is mainly used with performance concrete applications such as slab-on-grade, shotcrete, tilt-up panels, architectural/colored concrete, precast – anywhere that optimum fiber performance is required, and where the objective is to control temperature/shrinkage/settlement cracking while improving long-term durability properties.
Requires No Mix Design or Placement Changes!
Optimal Dosage Guidelines
Recommended dosage rate of FORTA ULTRA-NET is 1.6 lbs. per cubic yard (1.0 kg. per cubic meter) of concrete added directly to the concrete mixing system during, or after, the batching of the other ingredients, and mixed at the time and speed recommended by the mixer manufacturer (usually four to five minutes).

As the first synthetic fiber in the U. S. market in 1978, this premium-performance fiber excels in uniform mixing and resulting crack control. The added color blends well with cured concrete, assisting efforts to minimize fiber appearance on the finished surface.
FORTA ULTRA-NET is a unique twisted-bundle fiber that mixes and distributes extremely well in the concrete, even at desirable longer lengths. Due to the heavy-duty design, FORTA ULTRA-NET easily acts as an alternate to non-structural temperature/shrinkage steel reinforcement in a wide variety of flatwork, precast, and shotcrete applications.
