DonFiber PP-M is a 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-M within a concrete mix or cementitious mixes will reduce and control plastic shrinkage cracks and early age cracks.


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

  • Slab on grade.
  • Elevated slabs.
  • Parking areas.
  • Precast concrete.
  • Coatings and screed concrete.
  • Shotcrete.
  • Highway, railway, bridge decks.
  • Industrial and residential floors.
  • 1.0 lb or 1.5 lb (453 g, 680 g) water soluble PE packs.
  • 11 lb (5 kg) plastic bags.

Other packaging is available upon request.


Dosage of DonFiber PP-M will vary depending on the area of application and the required properties of concrete mixes. Typical dosage is between 1.0 - 1.5 lb/yd³ (0.6 - 0.9 kg/m³) of concrete.


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