Synthetic Fibres

Engineered Strength, Reliable Performance

Oscrete’s synthetic fibres deliver advanced crack control and durability across a wide range of concrete applications. Designed to replace or complement traditional reinforcement methods, our fibres are available in both macro and micro formats—each tailored to specific stages of concrete performance.

Macro Synthetic Fibres – Structural Crack Control

Macro fibres are high-performance synthetic filaments engineered for post-crack load redistribution and long-term crack resistance in hardened concrete. They are widely used as a sustainable alternative to steel mesh or rebar in large ground-supported slabs.

Key Benefits

  • Controls shrinkage and thermal cracking
  • Enhances load transfer and impact resistance
  • Eliminates corrosion risk compared to steel reinforcement
  • Simplifies site logistics and speeds up installation

Available Size:

  • 54mm fibres – Ideal for heavy-duty structural applications where maximum crack control and load transfer are required.

Micro Synthetic Fibres – Plastic Shrinkage Control

Micro fibres are thin monofilament strands designed to act during the early plastic phase of concrete, preventing plastic shrinkage cracking before it develops.

Key Benefits

  • Disrupts capillary bleeding
  • Reduces micro-cracking on horizontal surfaces
  • Improves cohesion and finish consistency
  • Compatible with most admixture systems

Applications:

  • Ready-mix concrete
  • Screeds and overlays
  • Slabs and pavements
  • Rapid-setting mortars

Why Fibre Size Matters

Oscrete’s 54mm macro fibres provide enhanced structural performance, making them ideal for industrial floors, ground-supported slabs, and areas subject to high loads. Their longer length ensures maximum crack control and effective load transfer in demanding applications.
