Monofilament polypropylene fibre for concrete and mortar

SikaFiber® is based on high quality monofilament micro polypropylene fibres. It is designed to minimize and control plastic shrinkage cracks by increasing the strain capacity of fresh concrete. SikaFiber® is available in premeasured, ready in use degradable bags for 1m3 of concrete.

Due to their fineness and special surface treatment, SikaFiber® can be easily dispersed in the concrete or mortar and create a dense matrix that leads to:
  • Improved cohesiveness of the fresh concrete
  • Reduced plastic shrinkage cracks
  • Reduced bleeding
  • Increased abrasion properties
  • Improved freezing and thawing resistance
  • When used in shotcrete, it reduces rebound waste
  • Increased resistance to impact loads
  • Reduced concrete permeability
  • Resistance to slab curling
  • Improved fire damage properties
