INTERBETON, with a steadfast commitment to technical excellence, offers INTERFIBER to the Greek market—a high-performance solution that improves the quality and reliability of ready-mix concrete from placement through long-term durability. By incorporating high-tensile-strength monofilament polypropylene fibers, INTERFIBER forms a three-dimensional micro-reinforcement network within the fresh concrete. This significantly reduces plastic-shrinkage microcracking, improves cohesiveness and workability, and increases the overall durability of the concrete structure.
This advanced technology is crucial for maintaining technical quality and long-term project reliability, while also improving sustainability by reducing repair needs and extending the service life of structural elements.
INTERFIBER is a complete technological solution for early-stage damage prevention. With its engineered composition, consistent performance, and quick response, it provides stronger, more dependable concrete with reduced maintenance needs. Integrating circular economy and sustainable construction principles, INTERFIBER is an excellent choice for structures that prioritize long-term durability, performance, and environmental responsibility.

INTERFIBER incorporates polypropylene fibers fully and uniformly during production, providing structural and functional benefits from the early stages of setting and hardening. The fibers disperse throughout the entire concrete mass and become active during the setting phase, addressing internal stresses and preventing the development of microcracks that compromise durability.
• Reduces plastic shrinkage and prevents early cracking, improving durability, significantly reducing permeability, and slowing carbonation and chloride ingress
• Creates three-dimensional micro-reinforcement, improving cohesiveness and mechanical stability during the early stages of hardening
• Mitigates internal stresses caused by water evaporation before the final setting
• Ensures full fiber dispersion, delivering uniform performance throughout the entire mass
• Reduces bleeding and porosity, enhancing resistance to wear and chemical attacks, lowering water and chemical absorption, and maintaining a cleaner long-term surface
• Prevents damage and reduces the need for repair materials, lowering CO₂ emissions associated with reconstruction

INTERFIBER demonstrates that small-scale improvements can have large-scale impacts. Early microcracks and initial-age deterioration are among the primary causes of long-term structural weakening and higher maintenance costs.
By acting at the root of the problem, where deterioration begins, INTERFIBER forms a threedimensional protective micro-mesh inside the concrete mass. It controls internal stresses, minimizes cracking and increases structural stability from the first hours of hardening. This leads to greater durability, a longer service life, and improved overall performance, while also lowering maintenance needs and CO₂ emissions associated with future repairs.
