Fill dirt

Fill dirt is like a big pile of dirt that is used to fill in holes or to make the ground level. Picture having a sandbox, but instead of sand, it’s a big pile of dirt. This dirt can come from different places like construction sites, farms, or even from land that is being excavated.

People might need fill dirt if they are building something new, like a house or a road, and the ground is uneven or has holes. The dirt is used to fill in those spaces so everything becomes level and even.

Fill dirt isn’t just any old dirt. It has to have a specific quality to it. It can’t be too rocky or filled with debris, like old pipes or concrete pieces. If the dirt has a lot of junk in it, it’s called “dirty dirt” and can't be used for construction.

Sometimes the dirt has to be tested by special machines to make sure it’s safe and it will be sturdy enough.

So, fill dirt is like a big pile of dirt that helps builders fill spaces and make the ground even, but it can’t be dirty or filled with junk.
