Easy to mix and evenly disperse, they enhance wear resistance and durability across a variety of cementitious applications, from floors and driveways to renders and plasters. Trusted by professionals for consistent, long-lasting concrete performance. ## Description Concrete Reinforcing Fibres. Easy to use. Disperses quickly & evenly. Minimises shrinkage and cracking. For extra strong concrete floors, paths, drives and shed bases. Suitable for use in sand & cement, and also in rendering,undercoat & one coat plasters. Fine monofilament polypropylene fibre material, which can be added to cementitious mixes to help prevent shrinking and cracking during the curing process. Fibres also enhance the surface properties and durability of hardened cement based materials. Ideal for use in concrete floor screeds, paths, driveways and garage/shed bases. Typical Uses: Internal floor slabs. Garages or shed bases. Driveways and paths. Underground construction. Imprinted concrete driveways. Features & Benefits: Reduces shrinkage and cracking in mortar mixes. Improves freeze thaw resistance. Reduces permeability of mixes. Improves impact and abrasion resistance. Reduces surface bleeding. Instructions for Use: Use 900g of fibres to treat one cubic meter. A suitable concrete mix relevant to the application must be used, e.g. for a shed base use 25kg of cement, 50kg sand and 100kg of gravel plus water. Proportion dose accordingly. Add aggregates (e.g sand or ballast). Add cement and mix thoroughly. Evenly mix with the dry concrete mix. Ensure that fibres are evenly dispersed within the dry mix.Add water and mix thoroughly. Concrete mix is now ready to be used. ## Features - 900g is enough for 1 cubic metre - Easy to use, quickly disperses in the mix - Reduces plastic shrinkage cracks - increases concrete and screed wear resistance - improves inflexional character of concrete ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013EPQXJE | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 11,239 in DIY & Tools ( See Top 100 in DIY & Tools ) 5 in Concrete | | Colour | 900g X 19mm | | Customer Reviews | 4.6 4.6 out of 5 stars (831) | | Date First Available | 16 Oct. 2014 | | Item Package Quantity | 1 | | Item Weight | 900 g | | Item model number | BWC900g | | Manufacturer | Build with Colour | | Part Number | BWC900g | | Product Dimensions | 37.08 x 26.67 x 3.81 cm; 900 g | ## Images ![900g Bags x 19mm Polyproylene (pp) Fibres for Concrete and Screed Reduces Shrinkage and Cracking - Image 1](https://m.media-amazon.com/images/I/41psmB1wqAL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Hi there would this be ok to use in concrete to make a pizza oven , ok with heat many thanks** A: I wouldn’t recommend these in a heated situation as they will melt. Concrete is not great in fire either unless you use heat resistant aggregate or crushed brick and heat resistant cement (Outdoor oven cement). If the mixture is fairly dry it shouldn't need fibres just keep the surface damp and protected from sunshine and rain whist it cures. You could use tile or brick to create shape with mortar (using heat resistant cement) Alex **Q: Do these come through when rubbing up render?** A: I've used them in multi finish and self leveling compound 🤷🏻‍♂️ I've had no problem 👍👍👍 **Q: How much do you use roughly per 25kg of cement? Thanks** A: A small hand full sprinkled into the mixer as it's rotating to ensure it does not clump. **Q: As I need a smooth clean surface I wonder if I add the fibers will they appear on the concrete surface?** A: No, not so far. We used these fibres for a cement pond lining six months ago, and apart from the smooth finish we have no cracks appearing or any other visible problems. ## Frequently Bought Together - 900g Bags x 19mm Polyproylene (pp) Fibres for Concrete and Screed Reduces Shrinkage and Cracking - Sika SikaBond SBR+ Waterproof General Purpose Bonding Agent and Admixture for Mortar,Screeds and Renders - 5L --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/74472224-900g-bags-x-19mm-polyproylene-pp-fibres-for-concrete-screed](https://www.desertcart.tn/products/74472224-900g-bags-x-19mm-polyproylene-pp-fibres-for-concrete-screed) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-24*
