FiberForce 950

FiberForce 950TM  is a blend of macrosynthetic and microsynthetic monofilament fibers. FiberForce 950 fibers are primarily used as secondary post-first crack reinforcement and will also provide plastic shrinkage reinforcement in concrete.


Interior Slabs-on-Ground
  • Commercial
  • Light, Medium, and Heavy Industrial Warehouse Sites
Exterior Slabs-on-Ground
  • Ingress-egress Roadways (Malls, Industrial, and Warehouse)
  • Parking Facilities
  • State DOTs and other Specifications or Code Applications
  • Bridge Decks

Recommendations for Use

Recommended dosage rate is between, but not limited to, 5 – 7 lbs. per cubic yard.

FiberForce 950 fibers are not to be used to replace primary, load-bearing steel reinforcement.

Mixing Instructions

FiberForce 950 is packaged in water-soluble bags that can be added directly into the concrete mix.

To ensure optimum distribution of the fibers, FiberForce 950 must be put at the middle or end of the load (in ready-mix trucks).

A minimum of 75-100 revolutions at mixing speed or 5-7 minutes of mixing at high speed may be needed to ensure complete dispersion of the fibers.

Our Professional Engineers are available for consultation.
