Corehfil™ Fibre

What is Corehfil™ Fibre?

SAPY has combined its experience in industrial fibre technologies with its mission to produce fibres for the concrete and cementitious industry, to introduce its brand Corehfil™ Fibre. SAPY’s Corehfil™ Fibres are manufactured from a proprietary formulation of polypropylene polymer and can be divided into microfibers and macrofibers depending on their length and the function that they perform in the concrete.

Key Applications

Synthetic fibre-reinforced concrete is used in a variety of applications, including Commercial, Industrial & Residential Floor Slabs; Bridge Decks; Precast Concrete Products; Plasters & Mortars; Thin Panels; Architectural Finishes; Refractory Casting Moulds; Marine & Hydraulic Structures and Shotcrete where its enhanced performance characteristics offer significant advantages over traditional concrete.

Corehfil™ PP Microfibre

Corehfil™ PP Microfibre is specially manufactured synthetic polypropylene fibre designed to reduce crack formation in cementitious construction materials by improving its resistance to early age shrinkage cracking.


Benefits of use include

  • Lower cost secondary reinforcement
  • Reduced concrete cracking due to plastic shrinkage and settlement
  • Reduced permeability by inhibiting surface cracking
  • Improved impact and abrasion resistance
  • Increased tensile and flexural ductility
  • Light, clean and safe to use

Corehfil™ PP Macrofibre

Corehfil™ PP Macrofibre is designed as a good alternative to mesh reinforcement, supplementing but not replacing structural reinforcement. Unlike crack control mesh, Corehfil™ PP Macrofibre forms a three dimensional bond with the concrete matrix, significantly improving the control of plastic settlement cracking.

Benefits of use include

  • Lower cost
  • Can be mixed easily and homogeneously with concrete
  • Improved impact and abrasion resistance
  • Long-term durability especially in corrosive environments
  • Increased tensile and flexural ductility
  • Easy to transport, store and handle
