Is it true that sloping removes material for protection?

Sloping refers to the technique of cutting back the face of a trench or excavation to create an inclined surface instead of a vertical one. This method not only allows for better stability and safety in excavation sites but also effectively helps in managing the surrounding materials to protect against potential collapses. By sloping, the excavator removes material from the edges, thereby reducing the weight and pressure on the walls of the trench or excavation, which is essential for preventing cave-ins.

This practice is particularly important because different types of soil have varying levels of cohesiveness and stability; sloping provides a general solution to enhance the safety of excavated areas, regardless of soil type or depth. Therefore, the statement that sloping removes material for protection is accurate.
