The best way to build something is from the ground up. But sometimes, you might need to do a little digging to really give your structure a strong foundation. The process of moving and relocating earth, rocks, and other debris is called excavation. Excavation is important to many fields such as mining, earth restoration, and of course, construction. This creates a blank canvas for builders to put up a building that is sure to be strong and properly placed. This task usually involves heavy equipment, machinery, and sometimes, even explosives.
