Pervious Concrete

What Is Pervious Concrete?

Pervious concrete is an innovative and environmentally friendly form that allows stormwater to pass through and into the soil beneath. It is an ideal choice for preventing flooding and managing stormwater runoff. This type of concrete is created by adding larger aggregate pieces and voids to the concrete mixture. The concrete voids allow water to collect and permeate the soil beneath.

Pervious concrete is used in various applications, such as roads, driveways, sidewalks, and parking lots. The biggest advantage of using pervious concrete is that it can reduce runoff and the amount of pollutants entering waterways. It also allows the soil beneath to filter pollutants before it naturally enters the water supply. This type of concrete is becoming increasingly popular as more people become aware of its environmental benefits.

In addition, previous concrete can reduce the urban heat island effect and improve air quality. This is because it allows rainwater to penetrate the surface and cool the air. The voids also provide air gaps which can improve air circulation and reduce air temperatures. Furthermore, previous concrete can be used to create easier-to-maintain pathways. These pathways are safer and more aesthetically pleasing than traditional concrete.

Advantages of Pervious Concrete

Pervious concrete is increasingly becoming popular among builders and designers due to its many advantages. Pervious concrete comprises specially graded, washed, and screened coarse aggregate blended with a small quantity of cement, water, and admixtures. This type of concrete is highly porous, making it an excellent choice for parking lots, driveways, sidewalks, and other impervious surfaces.

Reduced Runoff

Permeable concrete is often used to reduce stormwater runoff. Compared to traditional concrete, this type of concrete is designed with large voids, allowing surface water to pass through the material and infiltrate the ground. Infiltrating water into the ground not only reduces the amount of runoff but also recharges groundwater levels. Pervious concrete is a cost-effective choice for those looking to reduce runoff and seek alternative means of stormwater management compared to traditional methods.

Improved Drainage

Pervious concrete is ideal for drainage situations with an elevated water table, as the porous surface can absorb and filter runoff from the pavement. The concrete combines impermeable and porous surfaces, allowing water to flow through the material and collect in an underlying stone reservoir. When there is a large amount of precipitation, the porous surface releases the captured water into a drainage system, preventing flooding and other water-related issues. This also reduces the chances of water runoff carrying pollutants into nearby bodies of water. Furthermore, the concrete’s improved drainage capabilities can reduce the runoff leaving the site and help keep adjacent areas dry.

Energy Efficiency

This is an important factor to consider when deciding to use previous concrete. Pervious concrete has been found to reduce energy costs in the heating and cooling of buildings when used on pavements and sites. This is due to its ability to absorb, store and slowly release absorbed solar energy during peak demand periods. The porous nature of the concrete allows for better airflow, potentially reducing the need for air conditioning. Reducing runoff from rain and snow can also reduce energy associated with stormwater management. This makes previous concrete attractive for those wanting to create an energy-efficient environment.

Disadvantages of Pervious Concrete

Pervious concrete has numerous practical and economical benefits, but it has drawbacks. The primary disadvantage of pervious concrete is that it requires a higher level of maintenance to ensure longevity. The material is highly porous, which means it is subject to clogging by organic materials, such as leaves and debris. Additionally, the surface of pervious concrete is highly susceptible to wear and tear due to tire marks and heavy loads.

Pervious concrete is also more expensive than traditional concrete. While it is a cost-effective solution for managing stormwater, it is not cost-effective compared to other traditional materials. To install previous concrete properly, labor and installation costs are more complex and higher than traditional concrete. Also, the material requires special mixing equipment and special stabilization techniques with additional materials to prevent clogging.

Finally, the strength of pervious concrete is substantially lower than traditional concrete. The material must be replaced or reinforced at regular intervals to ensure that the surface does not crumble or crack. This can involve additional expense and labor costs. Additionally, the pavement should be sealed to prevent water infiltration through joints, which can increase cost.

Despite its disadvantages, previous concrete offers several benefits that make up for its shortcomings. It is an economical way to manage stormwater runoff and can provide several other environmental benefits. Proper material maintenance is required to ensure its full potential, but this cost is minor compared to the benefits it provides.

Applications of Pervious Concrete

Pervious concrete is a unique material with several different applications in commercial, residential, and industrial settings. Pervious concrete is an innovative material composed of a large aggregate, sand, a small amount of cement, and water, which is mixed and poured into a mold to form a permeable pavement.

One of the most popular uses of pervious concrete is in parking lots, driveways, and other asphalt surfaces. It is a porous surface that allows water to pass through it, reducing stormwater runoff, urban flooding, and associated environmental issues. For this use, pervious concrete can be used alone or combined with other drainage and stormwater management systems such as bioretention systems and rain gardens.

Pervious concrete is increasingly being used in residential settings, where it is utilized as a porous surface for patios, driveways, pool decks, and walkways. Pervious concrete offers homeowners a more environmentally friendly alternative to traditional asphalt or concrete, allowing water to pass through and preventing runoff from entering the stormwater system. Additionally, pervious concrete is cooler than regular concrete, making it a more comfortable walking surface.

In industrial settings, previous concrete is often used to pave roads, access ways, and hardstands. Pervious concrete provides a durable and resilient surface for heavy industrial traffic. It is also more porous than traditional asphalt surfaces, allowing the water to filter down and recharge groundwater resources.

Overall, the use of previous concrete is increasing due to its many environmental, economic, and durability benefits. Its wide range of applications and versatility make it a great option for any situation where stormwater management, permeability, and resilience are desired.
