Self-leveling refers to a process where a material, often a liquid or semi-liquid, spreads out evenly to create a flat surface. This is commonly used in construction and flooring, where self-leveling compounds are applied to ensure that surfaces are smooth and level before laying down tiles or other flooring materials. The technology behind self-leveling relies on gravity and the fluidity of the material. As the compound is poured, it flows into low spots and fills in gaps, allowing it to settle into a uniform layer. This helps to eliminate imperfections and provides a stable base for further construction or decoration.
