When building or renovating a floor surface, many people struggle with uneven or rough concrete that affects the final flooring finish. Self levelling concrete is widely used to create smooth, flat, and durable surfaces before installing tiles, vinyl, carpet, timber flooring, or epoxy coatings. It helps correct surface imperfections and provides a stable base that supports long-lasting flooring results.
What Is Self Levelling Concrete?
Self levelling concrete is a high-performance cement-based mixture that flows easily and spreads uniformly across the floor. Unlike traditional concrete, it does not require extensive manual trowelling. Once poured, it naturally settles to create an even surface, filling dips and low points without much effort.
It can be applied in homes, commercial areas, garages, and industrial floors where a perfectly level foundation is required.
Why Do Floors Need Levelling?
Uneven floors can cause issues such as:
- Cracked tiles and lifted floor coverings
- Difficulty installing flooring materials
- Water pooling or moisture problems
- Safety hazards such as tripping
Before flooring installation, ensuring the base is level prevents costly repairs later and increases the floor’s lifespan.
How Self Levelling Concrete Works
The mixture is combined with clean water and poured across the prepared surface. It flows across the floor and settles into a flat plane. Depending on thickness, it usually becomes walk-ready within hours. During drying, it bonds firmly to the existing surface, creating a strong and stable layer.
This process is commonly used after concrete floor preparation and can also support floor levelling systems for both small rooms and large commercial spaces.
