Every concrete application carries its own durability challenges whether it’s cracking in the early plastic phase, shrinkage over time, or structural integrity in demanding environments. Our range of high-performance fibres are designed to enhance concrete performance at every stage, improving cohesion, durability and appearance without the need for traditional steel reinforcement in many applications.
Fibres are added directly to the mix during batching or site mixing and disperse uniformly throughout the concrete matrix. By interrupting micro-crack formation and controlling shrinkage movement, fibres contribute to a tougher, more resilient product — especially valuable in floors, slabs, precast units, screeds, and repair applications.
Oscrete’s macro fibres are high-performance synthetic filaments used for post-crack load redistribution and long-term crack resistance in hardened concrete. They are often used as a sustainable alternative to steel mesh or rebar in large ground supported slabs.
Our micro fibres are thin monofilament strands designed to act during the early plastic phase of concrete specifically to prevent plastic shrinkage cracking.
They’re commonly used in ready-mix, screeds, slabs, overlays and rapid-setting mortars to combat environmental factors like wind and heat during early curing.
For glass fibre reinforced concrete (GRC) applications, Oscrete offers alkali-resistant glass fibres designed to maintain strength and integrity within cementitious environments.
AR glass fibres help distribute tensile stresses more evenly throughout the slab.
They minimise plastic shrinkage cracking and early-age thermal cracking — especially useful in large pours or exposed slabs.
AR fibres contain zirconia, making them chemically stable and resistant to alkali attack ensuring long-term performance.
They don’t interfere with finishing tools and can be used in power-trowelled surfaces without fibre protrusion (when properly dosed).
Ideal for slabs in aggressive environments (e.g., coastal zones, industrial floors) where steel corrosion is a concern.
AR fibres won’t rust, so they’re perfect for exposed or thin-section concrete.
Whether your objective is early-stage crack resistance, improved flexural strength, or a replacement for secondary steel reinforcement, Oscrete’s fibre technologies are supported by on-site technical support, trial planning, and mix optimisation services.
