Fitco Concrete Fibres

STRUCTO® macrofibres, is a macro synthetic fibre typically used as structural reinforcement in concrete and other construction materials.


Key features of STRUCTO

  • It's made from alkali resistant polyolefin material.
  • Longer and thicker compared to traditional FIBRIL microfibres. These dimensions provide improved performance and reinforcement characteristics.
  • A high tensile strenth, ensuring effective reinforcement in concrete and improving its resistance to cracking, impact, and fatigue.
  • A special surface that enhance their bonding capability with the surrounding matrix.
  • Helps control crack propagation in concrete; they distribute stress more evenly.
  • Typically added directly to concrete mix, making the process simple and efficient.
  • Resistance to Corrosion, making it suitable for various applications.
  • Compatible with various types of concrete, including regular concrete, shotcrete, precast concrete, and more. They can be used in both commercial and residential construction projects.
  • A cost-effective alternative to traditional reinforcement methods, such as steel reinforcement.


STRUCTO® macrofibres can be used in different types of (concrete) end products:

  • Precast concrete elements
  • Shotcrete
  • Pre-covering in tunnels
  • Extruded roadway structures
  • Rigid concrete floors
  • Foundation layers
  • Parking areas and airport runways
  • Consolidation of walls
  • Marine/coastal defence concrete


For simple application and dosage the fibres are packed into pucks, which is simply added to the wet concrete. These pucks are wrapped in film which dissolves within seconds during mixing and the individual fibres are distributed evenly throughout the concrete mixture. The pucks are packed in: boxes, plastic bags or (stackable) big bags.

STRUCTO® meets EN14889 class 2, CE-system of attestation 1

Different tensile strength possible

At Fitco, we have developed several STRUCTO® products over the past few years. This way, we can supply you with a product matching your needs. Next options are standardised: X55, XP55 (higher performance), X30 and X48.
