Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don't allow water to penetrate, forcing it to run off.
.
Accordingly, what is an example of an impervious surface?
Impervious surfaces are surfaces that allow little or no stormwater infiltration into the ground. Examples of impervious surfaces: Streets, roofs, parking lots, most patios, walkways, or anything else that does not allow water to flow through and into the ground (asphalt, concrete, plastics).
Also, what makes something impermeable? Something that is impermeable does not allow water or liquid to pass through it. Made up of the prefix im-, meaning “not,” and the adjective permeable, meaning “allowing to pass through,” impermeable is used in much the same way as impervious or impenetrable.
