Using a laser level is a common method to check the level of poured concrete because it provides a highly accurate and easy-to-read reference for horizontal planes. A laser level projects a beam of light that indicates a precise level line across a distance, allowing for immediate visual confirmation of whether the concrete surface is level throughout the area being worked on. This method is particularly effective for large areas and ensures a consistent level across the entire slab, which can be essential for proper drainage and overall structural integrity.

Other methods, while useful, may not offer the same level of accuracy or ease for large-scale projects. For instance, using a measuring tape can help determine specific distances but does not provide a direct visual reference for leveling. A level bubble can indicate if an area is level but may require frequent adjustments and checks over larger surfaces. Using a straightedge can help check for levelness along a specific line but is less efficient than a laser level for covering larger areas quicky. Laser levels combine precision, efficiency, and ease of use, making them the preferred choice in modern concrete finishing practices.
