Just like public roads, your driveway is also not immune from potholes. So what should you do if you notice them forming on your driveway? The best option is to properly repair any potholes as soon as you see them. But what is the right way to fix potholes?

Common Problems Potholes In the Driveway Cause

Anybody who drives knows potholes are bad for cars. They can mess up your suspension and wheel mechanisms or cause your vehicle to lose balance. Your tire may even get stuck if the pothole is large and deep enough.

Potholes also worsen if left untreated. They hurt your home’s curb appeal and property value but also cause structural damage to your driveway. The longer you wait, the more expensive the repairs will be.

How do Potholes Form in Your Driveway?

If you have a gravel driveway, erosion from rainwater and gravel loss from frequent traffic will cause potholes to form. That’s because gravel is a loose material compared to other driveway paving options.

If you have an asphalt driveway, potholes eventually form due to the material’s contraction and expansion as weather changes throughout the year. Cold makes asphalt contract, and heat makes asphalt expand. This slowly tears up the structural integrity of your asphalt driveway, causing the surface to collapse into potholes.

A core rule when it comes to pothole repairs is to never use organic materials, such as wood chips, mulch, dirt, or soil. Organic material promotes plant growth, and the roots will cause further damage to your driveway.

To repair a gravel driveway, it’s best to refill the pothole with the original type of gravel. Sand, gravel, or crushed shell all work well with gravel driveways. To repair an asphalt driveway, you can use cold patch asphalt or concrete mix as the filler material. You can then seal your driveway for an additional layer of protection.

DIY vs. Hiring a Pro

If the potholes are too big or too deep, we recommend hiring an asphalt company. Meanwhile, most potholes on a gravel driveway can be easily filled by yourself without the need for any additional treatment or sealing.

Asphalt driveway repair costs between $1,071 and $4,011 and a gravel driveway repair costs $100 to $300 per project.

Frequently Asked Questions

Mulch is best used in garden beds and yards, not in your driveway as pothole filler. It is meant to stimulate plant growth. Upon repeated pressure, it turns into compost, which also serves as fertilizer for weeds to take over. The roots will then break into your driveway, leading to more material loss and structural collapses.

Things like gravel, crushed shells, or even sand works with shallow potholes. For larger damages, use cold patch asphalt or a concrete mix. Make sure you compress the material enough so it stays intact against the traffic. Loose gravel is the most affordable option in most cases, but concrete is often the most reliable and durable.
