Designed for both trade professionals and DIY enthusiasts, Siteworx Concrete & Screed Fibres provide a practical solution for minimizing shrinkage and cracking in concrete and screed mixes. These 20mm polypropylene fibres significantly enhance the structural integrity and longevity of your finished work, ensuring a higher standard of craftsmanship; however, it is important to dose the mix correctly to ensure the fibres distribute evenly without clumping.

Yes, they are highly effective at minimizing shrinkage cracks in exterior slabs like driveways and pathways.
No. These fibres are for micro-reinforcement to control cracking. They do not provide the structural load-bearing capacity of steel bars or mesh.
No, they are made from polypropylene, which is a synthetic material and is completely corrosion-resistant.
The coverage depends on your specific mix design. Please refer to your concrete or screed manufacturer's dosage recommendations for fibre reinforcement.
While possible, it is highly recommended to use a mechanical mixer to ensure the fibres are evenly distributed throughout the batch.
Reduce the rate of addition; ensure the mixer is running at a consistent speed and increase mixing time.
Use a power float or trowel to ensure proper finishing; alternatively, light surface sanding once cured can remove protruding fibres.
To ensure success, add the fibres to your mixer along with the dry components before introducing all the water, or sprinkle them gradually into the wet mix if using a high-speed mechanical mixer. They are compatible with all standard cement types and common admixtures. Store the product in a cool, dry place and keep the bag sealed until you are ready to pour to prevent moisture exposure. These fibres do not require special personal protective equipment beyond standard site safety gear, but avoid inhaling dust when opening the packet.
