DonFiber PP Ultra
Ultra-fine, high performance monofilament polypropylene fibers
  • Controls and inhibits crack formulation caused by plastic shrinkage, settlement or other internal stresses in concrete.
  • Reduces shotcrete rebound.
  • Improves fresh mix properties (homogeneity & cohesiveness).
  • Increases concrete durability.
  • Easily distributed throughout the cementitious mix.
  • Compatible with all types of cement and concrete admixtures.
  • Rust-free.
  • Reduces bleeding.
  • Higher fiber count per Kg than standard monofilament fiber resulting in lower dosages.
  • Rust-free.

DonFiber PP Ultra is an ultra-fine denier, monofilament micro fiber reinforcement, manufactured of 100% polypropylene fibers containing no polyamide, nylon or reprocessed olefin materials. It is designed for use with all cementitious mixes.

The inclusion of DonFiber PP Ultra within a concrete mix or cementitious mixes will reduce and control plastic shrinkage cracks and early age cracks.


DonFiber PP Ultra is ideally designed to decrease the plastic shrinkage cracking and plastic settlement cracking in the following applications:

  • Slab on grade.
  • Elevated slabs.
  • Parking areas.
  • Stamped concrete.
  • Precast concrete.
  • Water tanks.
  • Pavements.
  • Shotcrete.
  • Renders.
  • Composite decks.

DonFiber PP Ultra is available in two grades:

  • Single length: 0.2", 0.5", 0.7" (6,12,18 mm).
  • Graded: 0.2", 0.5", 0.7" (6,12,18 mm) mixture.

Filled in:

  • 0.66, 1.32, 1.98 lb (300, 600, 900 gram) water soluble PE packs.
  • 11 lb (5 kg) plastic bags.

Other packaging is available upon request.


Dosage of DonFiber PP Ultra will vary depending on the area of application and the required properties of concrete mixes. Typical dosage is between 0.5 - 1.5 lb/yd³ ( 0.3 - 0.9 kg/m³) of concrete.


DonFiber PP Ultra complies with the requirements of ASTM C1116, Type III and EN 14889 Part II, Type 1A.
