Okay kiddo, have you ever seen a sidewalk or a driveway before? It's a hard, flat surface that you can walk on. But sometimes when it rains, the water can't soak into the ground because the surface is too hard. That's where pervious concrete comes in.
Pervious concrete is just like regular concrete, but with one big difference: it has tiny holes in it that let water seep through. This means that when it rains, the water can soak into the ground underneath the concrete instead of just flowing away.
Think of it like a sponge. When you spill water on a sponge, the water goes into the sponge instead of just sitting on top. Pervious concrete is like a big sponge that lets rainwater go where it's supposed to go.
Pervious concrete is good for the environment because it helps prevent flooding and erosion. It also helps keep the water clean by filtering out pollutants and other things that can harm plants and animals.
So the next time you see a sidewalk or driveway made of pervious concrete, remember that it's helping the earth by giving rainwater a place to go!
