How Good Drainage Saves You Time and Money

When it comes to asphalt surfaces, one of the most important factors in maintaining their durability and longevity is proper drainage. Without effective drainage, water can damage your driveway or parking lot, leading to cracks, potholes, and expensive repairs. At Asphalt Experts, we believe that understanding the role of drainage in asphalt care can help homeowners and business owners avoid costly mistakes. Here’s everything you need to know about why proper drainage is key to long-term asphalt durability.

Water: Asphalt’s Biggest Enemy

Water may seem harmless, but it is one of the biggest threats to asphalt surfaces. When water sits on asphalt, it slowly seeps into the material. Over time, this can weaken the base underneath the asphalt, causing cracks and holes to form. During the colder months, water trapped in cracks can freeze and expand, making the cracks larger and causing even more damage. This freeze-thaw cycle is especially harmful in regions with cold winters, such as Utah, where Asphalt Experts operates.

Without proper drainage, even a well-paved asphalt surface can deteriorate much faster than expected. That’s why ensuring water flows off your driveway or parking lot efficiently is essential for preserving its durability.

How Poor Drainage Damages Asphalt

Here are some common ways poor drainage can damage your asphalt:

1. Pooling Water: When water pools on your asphalt surface, it increases the chances of water seeping into the material. This weakens the structure and can cause cracks to form. Over time, these cracks widen, leading to potholes and more serious structural problems.

2. Erosion of the Base: Asphalt surfaces rely on a strong base for support. If water infiltrates the base layer, it can cause erosion, leading to uneven surfaces and instability. Once the base is compromised, the entire structure of your driveway or parking lot becomes vulnerable.

3. Weakened Surface: Asphalt is durable, but it isn’t indestructible. Constant exposure to standing water can degrade the asphalt binder, the glue that holds the aggregate together. When the binder breaks down, the surface becomes brittle and starts to crack.

4. Freeze-Thaw Damage: As mentioned earlier, the freeze-thaw cycle is particularly destructive. When water enters small cracks in the asphalt, it expands when it freezes, making the cracks worse. This repeated cycle can result in major damage over a short period.

Importance of Sloping and Grading

One of the best ways to prevent water damage to asphalt is by ensuring proper sloping and grading during the installation process. The surface should be slightly angled to allow water to flow away from the asphalt. If your driveway or parking lot is flat or has improper grading, water will pool in low spots, leading to long-term damage.

At Asphalt Experts, we make sure every asphalt project is correctly graded to prevent water from sitting on the surface. We aim to create a smooth and durable surface that efficiently directs water to drainage systems or off the pavement, extending the life of your asphalt.

Proper Drainage Systems

For larger asphalt surfaces like commercial parking lots, additional drainage solutions are often necessary to handle the volume of water. Some common drainage systems include:

1. French Drains: These are trenches filled with gravel and pipes that help redirect water away from the asphalt surface.

2. Catch Basins: These collect water and direct it to an underground drainage system, preventing it from pooling on the asphalt.

3. Gutters and Downspouts: These are especially useful for managing runoff from nearby structures, ensuring that rainwater doesn’t flood your asphalt surface.

How to Identify Drainage Problems

Asphalt drainage problems aren’t always immediately visible, but there are some signs that property owners can look for to spot potential issues. Here’s what to watch out for:

• Standing Water: If you notice puddles forming on your driveway or parking lot after it rains, this is a clear sign that your drainage isn’t working properly.

• Cracking and Potholes: Cracks, especially those that seem to widen over time, can indicate that water is seeping into the surface. Potholes are another major red flag.

• Uneven Surfaces: If certain areas of your asphalt appear lower than others, it could be due to erosion of the base caused by poor drainage.

• Weeds Growing Through Cracks: Vegetation growing through cracks in the asphalt is a sign that the integrity of the surface has been compromised, often due to water infiltration.

Preventive Measures for Asphalt Longevity

Preventing drainage issues starts with choosing a reliable asphalt contractor who understands the importance of proper grading and drainage solutions. At Asphalt Experts, we ensure every project is carefully planned and executed to avoid water damage. Here are a few preventive measures to keep your asphalt surface in good shape:

• Regular Inspections: Conduct regular inspections of your driveway or parking lot to catch any drainage problems early.

• Sealcoating: Applying a sealcoat every 2-3 years helps to protect your asphalt from water infiltration and the damaging effects of UV rays.

• Crack Sealing: Address cracks as soon as they appear to prevent water from entering and causing further damage.

• Proper Maintenance: Regularly clean your asphalt surface and keep drainage systems clear of debris to ensure water flows away as intended.

Proper drainage is critical to the long-term durability of your asphalt driveway or parking lot. Water can wreak havoc on asphalt surfaces, causing cracks, potholes, and even structural damage if left unchecked. At Asphalt Experts, we understand the importance of good drainage and take every step to ensure your asphalt lasts as long as possible. By investing in proper installation, grading, and maintenance, you can protect your asphalt from water damage and extend its lifespan for years to come.
