7 Brilliant Benefits of Fibre Reinforced Self Levelling Compounds / Screeds

Combining the convenience of flowable, easy-to-apply levelling products with the added strength of fibre technology, these fibre reinforced self levelling compounds are transforming how contractors approach subfloor preparation.

1. Superior Crack Resistance

Standard self-levelling compounds can be prone to hairline cracks as they cure or under thermal and structural stress, whereas fibre reinforcement drastically improves crack resistance, as the fibres form a mesh-like internal matrix that absorbs and redistributes stress throughout the layer. This is particularly beneficial when working over substrates that experience slight movement or vibration.

2. Stronger, More Durable Resistance

Self levelling compounds that are fibre-reinforced compounds result in a harder, tougher finish that can withstand heavier foot traffic, rolling loads, and impact. Whether it’s a homes, commercial offices, retail units, or warehouse, the added resilience reduces the likelihood of surface damage before final floor coverings are applied.

3. Better Flexural and Tensile Strength

The inclusion of fibres boosts both tensile and flexural strength, meaning the levelling compound is better suited to bridge small cracks or minor substrate imperfections without failing. This also helps maintain integrity across larger pours or thinner applications.

4. Ideal For Use Over Underfloor Heating

Fibre-reinforced self-levelling compounds perform exceptionally well over underfloor heating systems, where the fibres provide better thermal movement control, and therefore reducing the risk of cracking or delamination as the system heats and cools. This ensures better longevity and fewer issues for the client down the line.

5. Fewer Reinforcement Materials Required

In many situations, fibre-reinforced levelling compounds can eliminate the need for metal mesh or crack-control matting, simplifying prep work and reducing the time needed. That’s less material to carry, less handling on site, and faster installation overall.

6. A Smooth & Even Finish

Despite the added strength, these compounds still flow and settle smoothly. This delivers the flat, even surface required for vinyl, laminate, carpet, or tiled finishes. You get all the performance benefits of reinforcement without compromising on quality.

7. Time & Cost Efficiency

While slightly more expensive per bag, fibre-reinforced levellers save money over the life of the job by reducing installation time, lowering the risk of failures, and minimising the need for additional reinforcement materials. It’s a smart choice for high-performance jobs that demand speed and durability.

In Summary

Whether you’re prepping a floor in a apartment, a busy retail unit, or a temperature-sensitive environment like a conservatory or heated floor zone, fibre-reinforced self-levelling compounds offer a distinct & clear advantage. With it’s better crack resistance, improved strength, and faster install times, they help you deliver longer-lasting results with fewer headaches. Fibre reinforced self levelling compounds are a game-changer!
