High Disperse 3mm Fibre is a high-performance, mineral-based micro-reinforcement designed to control cracking and enhance durability in concrete, GFRC, renders, and mortars. With a high elastic modulus and excellent bond to cement, these fibres provide three-dimensional reinforcement while remaining invisible on the surface, even in fine-detail work.

High Disperse 3mm Fibre is ideal for enhancing the performance of GFRC, decorative concrete, precast elements, and UHPC mixes. It disperses easily to form a uniform, three-dimensional reinforcement network that controls both plastic shrinkage and early-age cracking. With its high elastic modulus and excellent bond to cementitious materials, it increases flexural strength and post-crack integrity, while remaining invisible on finished surfaces—making it especially suitable for architectural or white concrete applications. Its mineral composition means it won’t rust or stain, and it performs exceptionally well in hot, dry, or windy conditions where cracking risks are elevated. The fibres have neutral buoyancy, so they neither float nor sink, ensuring even distribution throughout the mix. Easy to handle and apply, High Disperse 3mm Fibre can be added directly into the mixer or on-site, with minimal impact on workability. It pumps cleanly, doses easily through automated systems, and helps reduce chipping in fine details and edges—making it a smart, efficient solution for concrete reinforcement in both aesthetic and structural applications.
