The Importance of Proper Drainage for Your Asphalt Surface

The Importance of Proper Drainage for Your Asphalt Surface

November 2, 2023

When it comes to maintaining your asphalt surface, one often overlooked aspect is proper drainage. While it may not be a glamorous topic, ensuring that water is effectively drained from your asphalt surface is essential for its longevity and durability. In this blog post, we will explore why proper drainage is crucial for your asphalt surface and how it can prevent costly repairs in the long run. 

1. What is Proper Drainage? 

Proper drainage refers to the ability of your asphalt surface to effectively channel water away from its surface. This is typically achieved through the installation of a comprehensive network of drains, gutters, and slopes that direct the flow of water off the asphalt and towards designated areas, such as stormwater drains or other appropriate outlets. 

2. Prevents Water Damage 

One of the primary reasons why proper drainage is essential for your asphalt surface is that it prevents water damage. When water sits on the surface of your asphalt for extended periods, it gradually seeps through any cracks or pores in the pavement. Over time, this water can weaken the asphalt and compromise its structural integrity, leading to potholes, cracks, and other forms of damage. 

Moreover, when water penetrates the asphalt, it can also affect the underlying base layers. The base layers provide stability to the asphalt, and if they become saturated with water, they may settle or become unstable. This can cause the asphalt surface to sink or develop uneven depressions, making it unsafe for vehicular or pedestrian traffic. 

3. Extends Lifespan 

Investing in proper drainage significantly extends the lifespan of your asphalt surface. By effectively managing water runoff, you reduce the likelihood of water damage and subsequent repairs. 

When water is promptly drained away from the surface, it minimizes the exposure of the asphalt to moisture-related issues, such as freeze-thaw cycles. These cycles occur when water within the asphalt expands and contracts with temperature fluctuations, leading to cracks and potholes. By channeling water away from the asphalt, you can avoid this common problem and preserve the integrity of your pavement. 

4. Prevents Surface Ponding 

Improper drainage can result in surface ponding, the accumulation of water on your asphalt surface. When water remains stagnant for extended periods, it not only interferes with the aesthetic appeal of your pavement but also poses significant safety hazards. 

Surface ponding creates slip and fall risks, particularly during freezing temperatures when the water may turn into ice. It can also damage the top layer of the asphalt, leading to deterioration over time. By implementing proper drainage systems, you can effectively eliminate the occurrence of surface ponding and maintain a safe and attractive asphalt surface. 

5. Alleviates Flooding Risks 

In addition to protecting your asphalt surface, proper drainage also helps prevent flooding risks on your property. Without adequate drainage, excess water can accumulate and flood your parking lots, driveways, and other areas covered with asphalt. This can not only disrupt your daily operations but also incur significant costs for repairs and cleanup. 

By ensuring that water is efficiently drained away from your asphalt surface, you minimize the chances of flooding, keeping your property safe and accessible even during heavy rain events. 


Proper drainage is of utmost importance for your asphalt surface. It prevents water damage, extends the lifespan of your pavement, prevents surface ponding, and alleviates flooding risks. By investing in professional drainage solutions, you can protect your asphalt surface, save money on future repairs, and maintain a safe environment for all.
