What is the term for excavated material that is placed at ground level next to a trench?

The term for excavated material that is placed at ground level next to a trench is "spoil." When a trench is dug, the soil or material that is removed from the ground is referred to as spoil. This material is often left adjacent to the trench for various reasons, such as being used later for backfilling, or for ease of access while the excavation work is ongoing. Understanding this terminology is essential for proper site management and safety in excavation work, as it helps in assessing conditions around the trench and ensuring that the area remains safe for workers. The correct identification of spoil is particularly important for planning purposes, as it affects how safely one can work around the trench and manage the material created by the excavation process.
