Permeable concrete pavers are used to build strong, paved hardscapes that allow water to filter through the pavement itself into the ground below. Hardscapes built from these materials can support up to 8,000 pounds per square inch. At the same time, however, these surfaces prevent water from flooding surrounding areas. It also prevents pollutants in the water from running into storm sewers that drain into rivers and streams.
The ground itself works as a remarkable drain and filter in this respect. Water that goes directly into the earth is filtered to some degree by natural processes. Other systems can also be built into the infrastructure that will then send this water to treatment plants that remove toxic agents.
