Anti-Crak®  HD (High Dispersion) is an engineered AR-glass chopped strand designed for mixing in concrete and all hydraulic mortars.  The HD works like PVA and disperses in the mix and doesn’t show in the surface. Dosed usually at 0.5% of total dry weight.


  • High dispersion (220 million filaments per kg, 100 million per lb)
  • Excellent workability
  • Invisible on the finished surface
  • Does not corrode
  • Control and prevention of cracking in fresh concrete


Anti-Crak®  HD fibers are typically used at low addition level

to prevent cracking & improve the performance of concrete, flooring, renders or other special mortar mixes.

They incorporate easily into mixes creating a tridimensional homogeneous network of reinforcement in the matrix.

Anti-Crak®  HD fibers can be added at the central mixing plant to the wet concrete mix; or directly into the ready-mix truck.

Anti-Crak®  HD fibers do not protrude through the surface and require no additional finishing procedures. The reinforcement is incorporated in the concrete mass and is invisible on the finished surface.

  • Overall enhancement of durability and mechanical properties of concrete
  • Effective at very low dosage
  • Homogeneous mix

• Safe and easy to handle
