Porous paving, also called green paving, has become more and more popular over the years. However, while calling something green is an indication that it’s good for the environment, that doesn’t guarantee that people really understand what it does, or why it’s a positive influence. So if you’ve been thinking about installing porous paving, here’s a simple explanation of why it’s good for you, and for the earth.

How Does Porous Paving Work?

Traditional paving like concrete is solid. If it rains, then the water puddles on top of the paving, spilling off to either side when too much water accrues. That can lead to problems, since the water runoff carries contaminants like motor oil off the paving, and it can cause erosion as well.

Porous paving solves both of these issues at a single stroke.

As the name implies, porous paving is permeable. That means when water hits the pavement, it can flow down through it, and drain. This stops the water from running off to the sides, drowning plants, and eroding the soil.

Not only that, but porous paving takes the water (and any contaminants mixed in with it) through several layers of material. These layers act as a natural filter, ensuring the water returns to the water table, but that it doesn’t bring any unwanted or poisonous chemicals with it.
