Can Asphalt Be Laid Over Concrete?
Asphalt driveways and pavements are often more preferred because it is more cost-effective, quicker to install, and easier to repair. Additionally, asphalt’s flexibility and smoother surface make it better suited for a quieter, safer driving experience. This leads to the question: “Can asphalt be laid over concrete?” Though the answer to this question is yes, there are some difficulties that would be encountered if asphalt is laid over existing concrete surfaces. Let us explore why laying asphalt over concrete is not recommended and how the concrete surface can be removed to lay asphalt over it.
Why is Laying Asphalt over Concrete not Recommended?
Problems due to Concrete Subbase: While laying concrete, the preparation of the ground is not given as much importance. This is because concrete is very stable and doesn’t require much preparation. However, asphalt needs a solid, well-prepared sub base because it is more flexible than concrete. If the ground underneath is unstable, asphalt can shift, crack, or sink over time.
Problems due to Concrete: If asphalt is laid over concrete, the concrete often has expansion joints that allow it to move with temperature changes. These joints can eventually cause the asphalt to crack where the concrete moves. If the expansion joints aren’t properly addressed, the asphalt will mirror the same issues, leading to cracks and surface damage. Additionally, if the concrete underneath is unstable or has areas of weakness, it cannot properly support the weight of the asphalt.
How HippoSeal Can Replace Concrete with Asphalt and Provide Ongoing Maintenance
1. Concrete Removal: At HippoSeal, we start by efficiently removing your old, cracked, or damaged concrete surface. Our team uses specialized equipment to break up and remove the concrete, ensuring minimal disruption to your property. This allows us to begin with a clean, smooth base, making way for a fresh asphalt installation.
2. Surface Preparation: Once the concrete is removed, we focus on properly preparing the sub-base underneath. At HippoSeal, we ensure that the ground is graded, compacted, and leveled to create a solid foundation for the new asphalt. Proper preparation is key to preventing future issues like cracks, settling, or uneven surfaces that can occur if the base isn’t stable.
3. Asphalt Installation: After preparing the sub-base, HippoSeal expertly installs your new asphalt surface. We use high-quality materials and follow industry best practices to ensure a smooth, durable, and long-lasting asphalt driveway or pavement. Our team ensures proper compaction and drainage to prevent water pooling, which can cause damage to the asphalt over time.
4. Ongoing Maintenance: At HippoSeal, we believe that proper maintenance is essential to extending the life of your new asphalt surface. We offer comprehensive maintenance services, including crack repairs, resealing, cleaning, and regular inspections.
