Monofilament Microfibers

Control of plastic shrinkage cracking

Monofilament Microfibers are a high-tensile strength, high modulus of elasticity, ultra-thin monofilament homopolymer polypropylene fiber designed to quickly distribute uniformly throughout the concrete matrix.

  • Residential and Commercial slabs-on-ground
  • Reduce plastic shrinkage cracking of concrete
  • Superior finishability makes it a good candidate for all residential applications
