Screeding is the process used to strike concrete to achieve the required surface elevation. This technique involves using a long, straight edge, often referred to as a screed board, to level the surface of freshly poured concrete. By moving the board back and forth across the top of the concrete, any excess material is removed, resulting in a uniform surface that conforms to the desired elevation and smoothness. This step is crucial in ensuring that the concrete has the correct thickness and finishes properly before it sets.

In contrast, mixing refers to the process of combining the raw materials (cement, water, aggregates) to create concrete, while forming involves setting up molds to shape the concrete as it cures. Curing is a subsequent process that ensures the concrete retains moisture as it hardens, which is essential for achieving its full strength. Each of these processes plays a vital role in the overall concrete installation, but screeding specifically is focused on achieving the necessary surface elevation immediately after pouring the concrete.
