Product Description
Polypropylene fibre (short-cut strands of very fine denier monofilament*) is added to the concrete during batching. Thousands of individual fibres are then evenly dispersed throughout the concrete during the mixing process creating a matrix-like structure.
Properties
- Improves concrete’s resistance to plastic shrinkage cracking.
- Inhibits formation of micro-cracks due to dimensional change.
- Reduces sedimentation.
- Increased cohesion of the mix.
- No requirement for crack control steel mesh.
- Concrete placement and crack control in ONE operation.
- Reduced bleeding.
- Less expensive (per m2) than conventional steel mesh reinforcement.
- Reduced plastic cracking means a reduction in surface permeability.
- Bleed water control inhibits migration of cement fines and sand to the surface.
- Even distribution of fibres throughout the concrete.
- A tougher surface with fewer bleed hole.
- Reduced plastic cracking means a reduction in surface permeability.
- Bleed water control inhibits migration of cement fines and sand to the surface.
- Even distribution of fibres throughout the concrete.
- A tougher surface with fewer bleed holes.
Benefits
- Reduced frequency of plastic cracking.
- Improved durability and reduced permeability.
- Decreases risk of plastic settlement cracking over re-bar.
- Reduced settlement and easier finishing.
- No delays to fast track schedule.
- Easier positioning of joints.
- No need to purchase and store additional material.
- Reduced site labour requirement.
- No secondary steel mesh is required and reinforcement is automatically positioned.
- Easier finishing of the concrete surface.
- Reduced project costs.
- Enhanced durability.
- Harder, more durable surface with better abrasion resistance.
- Improved flexural properties.
- Increased resistance to spalling at higher temperatures and so…. better fire resistance.
- Reduced absorption of water, chemicals and dirt.
Application
- Most small builder, cash sales and DIY applications
- Internal floor-slabs (retail stores, warehouses, etc.)
- External slabs (driveways, yards, etc.)
- Agricultural applications
- Roads, pavements, driveways, Kerbs
- Shotcrete; thin section walling
- Overlays, patch repair
- Water retaining structures, marine applications
- Security applications such as safes and strong rooms
- Deep lift walls

How to use
- The concrete can be compacted and finished normally. Trowelling embeds the fiber in the concrete surface.
- Some fibers may be exposed where textured finish is applied, but these quickly disappear.
- Batching fiber reinforced concrete - longer batch times.
- Concrete with fiber can be pumped in most cases.
- Control joints are necessary and should be spaced at normal intervals prescribed for an reinforced slab design.
