Understanding the Impervious Meaning

Learn about the impervious meaning and its significance in construction, environmental science, and engineering. Explore examples, case studies, and the impact of impervious surfaces on flooding.

What is Impervious Meaning?

Impervious meaning refers to something that is not able to be penetrated or affected by external factors. It is used to describe a substance or material that is resistant to water, air, or other substances. Understanding the impervious meaning can be important in various fields such as construction, environmental science, and engineering.

Examples of Impervious Materials

Some common examples of impervious materials include concrete, asphalt, and metal. These materials are used in construction to create barriers that are resistant to water infiltration. Impervious materials are also used in waterproof clothing, roofing materials, and protective coatings.

Benefits of Impervious Surfaces

Impervious surfaces can help prevent water damage, reduce erosion, and protect structures from weathering. They can also improve the durability and longevity of buildings and infrastructure. In urban areas, impervious surfaces are used to create roads, parking lots, and sidewalks that can withstand heavy traffic and weather conditions.

Case Studies

In a study conducted by the Environmental Protection Agency (EPA), researchers found that increasing impervious surfaces in urban areas can lead to higher levels of pollution in waterways. This is because impervious surfaces prevent rainwater from being absorbed into the ground, causing runoff that carries pollutants into rivers and streams.

Impervious Surfaces and Flooding

Impervious surfaces can also contribute to flooding by preventing water from being absorbed into the ground. This can lead to increased runoff during heavy rainfall events, overwhelming stormwater management systems and causing flooding in low-lying areas. In cities with high levels of impervious surfaces, such as New York City, flooding is a major concern.


Understanding the impervious meaning is important for ensuring the durability, safety, and sustainability of structures and infrastructure. By using impervious materials wisely and incorporating green infrastructure solutions, we can mitigate the negative impacts of impervious surfaces and create more resilient communities.
