Master Fibre is a high-quality synthetic fiber additive designed to reinforce concrete and mortar mixtures. It improves structural integrity by enhancing tensile strength, reducing cracking, and increasing durability. The fibers disperse uniformly within the mix, providing better load distribution and impact resistance in industrial, commercial, and residential construction applications. Master Fibre enhances performance without compromising workability, making it ideal for use in concrete slabs, pavements, beams, and repair mortars.

Master Fibre

Primary Uses

Concrete Reinforcement
Added to concrete to increase tensile strength and reduce shrinkage cracks during curing. Enhances impact and abrasion resistance in industrial floors, pavements, and precast concrete products.
Mortar and Plaster Enhancement
Improves bonding strength and reduces shrinkage cracks in mortar and plaster applications.
Structural Applications
Enhances durability and load-bearing capacity of structural elements such as beams, slabs, and walls. Used in fiber-reinforced concrete (FRC) systems for additional reinforcement.

Secondary Uses

Shotcrete Applications
Used in sprayed concrete for tunnels, retaining walls, and slope stabilization to improve toughness and adhesion.
Repair and Restoration
Incorporated in repair mortars and overlays to increase longevity and reduce surface cracking.
Decorative Concrete
Adds strength in stamped or colored concrete mixes while maintaining aesthetic qualities.
