Which procedure is commonly used to level freshly poured concrete flatwork?

Screeding is the procedure commonly used to level freshly poured concrete flatwork. This process involves using a straightedge, often referred to as a screed board, to smooth and level the surface of the concrete after it has been poured. The screed board is typically moved back and forth in a sawing motion across the forms to ensure an even surface and to remove excess concrete. This technique is crucial for achieving the desired thickness and flatness of the concrete slab, which is essential for the performance and aesthetics of the finished surface.

While shoveling may assist in spreading the concrete and initially distributing it within the forms, it does not provide the precision needed for leveling. Vibrating can help remove air pockets and ensure better consolidation within the concrete mix, but it does not effectively level the surface. Floating is a subsequent process used after screeding to further smooth the surface and finish the concrete, but it comes after the initial leveling has been achieved through screeding. Thus, screeding is the primary method for leveling freshly poured concrete flatwork.
