Asphalt is widely favored for driveways and pavement due to its affordability, ease of installation, and straightforward maintenance. Its smooth, quiet finish makes it ideal for residential and commercial use. But a common question many property owners ask is: Can asphalt be installed over an existing concrete surface?
The answer is technically yes but there are important factors to consider. Installing asphalt directly on top of concrete can create long-term issues if not done correctly. Let’s explore why this method is generally discouraged and how HippoSeal handles the process for long-lasting results.
Why Laying Asphalt Over Concrete Is Usually a Bad Idea
The Problem with Concrete Sub-Bases
Concrete is typically poured over a minimally prepared sub-base because of its rigid nature. However, asphalt is flexible and needs a strong, evenly compacted foundation to remain stable over time. If the base underneath the concrete is loose or uneven, it can lead to asphalt shifting, cracking, or forming low spots.
Movement in Concrete Leads to Asphalt Cracks
Concrete expands and contracts with temperature changes, which is why it includes expansion joints. When asphalt is applied directly over these joints, it often cracks in the same spots. Additionally, any flaws or damage in the concrete can reduce the durability of the asphalt layer laid over it.
Hipposeal’s Professional Approach to Asphalt Installation
At Hipposeal, we prioritize quality and longevity. That’s why we avoid shortcuts like overlaying asphalt on concrete and follow a proven installation process:
1. Concrete Removal
We begin by safely breaking up and removing the old concrete. Using specialized equipment, our team ensures a clean removal process that minimizes disruption to nearby areas.
2. Sub-Base Construction
After the concrete is cleared, we focus on building a strong sub-base. This involves grading, compacting, and leveling the ground to create a firm foundation for the asphalt. A well-prepared sub-base helps prevent issues like sinking, cracking, and poor drainage.
3. Asphalt Application
Once the base is ready, we apply a fresh layer of high-quality asphalt. Our team follows strict industry practices to ensure smoothness, proper compaction, and effective water runoff—key elements for a long-lasting surface.
4. Ongoing Asphalt Maintenance
To maximize the life of your new asphalt, Hipposeal offers routine maintenance, including sealing, crack filling, surface cleaning, and inspections. Our asphalt sealcoating services in Dalton and surrounding areas help preserve the look and strength of your driveway or pavement over time.
Final Thoughts
While laying asphalt over concrete might seem like a quicker and cheaper solution, it often leads to structural issues and higher costs in the long run. The real question isn't just "Can asphalt be laid over concrete?" but rather, "Is it the right choice?" and in most cases, the answer is no.
At Hipposeal, we believe in delivering results that last. By completely removing the concrete and preparing a solid foundation before installing asphalt, we ensure durability and satisfaction. With our sealcoating and maintenance services, your surface will remain strong and visually appealing for years.
