Monofilament Fibre – 100% Virgin Polypropylene (3mm) is a premium micro-reinforcement additive specially engineered for concrete, mortar, plaster, and screed applications. These lightweight yet extremely strong fibres effectively control plastic shrinkage cracks, bleeding, and segregation—ensuring improved structural integrity and surface quality.
The fibres disperse uniformly throughout the mix, forming a 3D reinforcement system that enhances durability, tensile strength, and resistance to impact and abrasion. Ideal for floors, plasters, overlays, repair mortars, water-retaining structures, industrial slabs, and all types of concrete works.
Unlike steel fibres, monofilament PP fibres are corrosion-free, alkali-resistant, non-magnetic, and extremely lightweight—making them safe, economical, and easy to mix into any cementitious formulation.
Perfect for contractors, ready-mix plants, waterproofing specialists, and builders who seek better performance, reduced cracking, and long-lasting results.
