What is Fibre Reinforced Screed?
Fibre reinforced screed is a traditional sand and cement screed that has been mixed with synthetic fibres. These fibres, typically made of polypropylene or other durable materials, are evenly distributed throughout the screed mix, providing additional structural support and reducing the risk of cracking and shrinkage.
Key Benefits
Increased Strength
The addition of fibres significantly increases the tensile and flexural strength of the screed, making it more resistant to cracking and deformation. This is especially beneficial in areas subjected to heavy loads and traffic. By adding reinforcing Polypropylene fibres to the mix it is possible to produce high strength screeds with compression strength in excess of 30 Nmm2
Reduced Shrinkage and Cracking
Fibres help to distribute stresses more evenly throughout the screed, reducing the likelihood of shrinkage cracks during the curing process. This ensures a more stable and durable floor.
Improved Durability
Fibre reinforced screed is more durable and resilient than traditional screed, offering better resistance to impact, abrasion, and wear. This extends the lifespan of the flooring system.
Enhanced Flexibility
The inclusion of fibres provides the screed with enhanced flexibility, allowing it to accommodate slight movements in the substrate without cracking or breaking.
Compatibility with Underfloor Heating
Fibre reinforced screed is ideal for use with underfloor heating systems. The fibres help to distribute the heat more evenly and reduce the risk of cracks caused by thermal expansion and contraction.
Improved Bonding
The fibres within the screed mix improve the bonding between the screed and the substrate, enhancing the overall integrity and stability of the flooring system.
Faster curing times
Ideally, a traditional screed surface should be left for a week before any foot traffic thus ensuring the longevity of the floor.

Application Process
The process of applying fibre reinforced screed involves several key steps to ensure a high-quality finish:
1. Surface Preparation
The substrate is thoroughly cleaned and any debris, dust, or contaminants are removed. Cracks and imperfections are repaired to create a solid base.
2. Mixing
The screed mixture is prepared by combining sand, cement, water, and synthetic fibres. Proper mixing is crucial to ensure the fibres are evenly distributed throughout the screed.
3. Application
The screed is poured onto the prepared substrate and spread evenly using trowels or specialized equipment. The screed is then leveled and smoothed to create a uniform surface.
4. Levelling
The screed is leveled to the desired thickness and smoothed to create an even surface. This step is crucial for ensuring the final floor covering can be properly installed.
5. Curing
The screed is allowed to cure for the specified period, which can vary based on the type of screed used. Proper curing is essential for achieving the desired strength and durability.
