Cut and fill is a common earthmoving technique used in civil engineering and construction. It involves the process of excavating material from areas designated as "cut" and using that excavated material to build up or "fill" adjacent areas. The primary goal is to balance the volume of earth removed with the volume of earth needed for embankment construction, thereby minimizing the need to import or export soil from the site.

The principles of cut and fill are applied to create desired landforms, such as leveling sites for buildings, constructing roads, creating agricultural terraces, or shaping landscapes. The process requires careful surveying and planning to determine the exact volumes of cut and fill required. Tools like topographic maps, digital terrain models, and specialized software are used to calculate these volumes and plan the excavation and placement of soil.

Efficient cut and fill operations aim for a balance where the volume of excavated material approximately equals the volume of material needed for filling. If the volume of cut exceeds the volume of fill, the excess material, known as spoil, must be removed from the site. Conversely, if the volume of fill exceeds the volume of cut, additional material, known as borrow, must be brought in. Minimizing spoil and borrow is economically advantageous as it reduces transportation costs and the environmental impact associated with material movement. The selection of suitable fill material is also crucial, as it must have adequate bearing capacity and stability.
