What causes concrete driveways to sink?

Erosion is a common cause of sunken concrete. Erosion washes away soil from under your driveway, creating a void or space under the concrete slab. Your driveway can begin to sink in areas where the soil has been washed out. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. A heavy load, such as an RV that’s kept in your driveway, can cause sections of the driveway to sink and crack over time. If you have a newer home with a sinking driveway, it could be because the ground around the house is settling or the base of the driveway was not compacted properly. A sinking driveway near your garage can lead to foundation cracks and expensive damage over time.

FAQ's

The first step toward concrete driveway repair is making sure you know the warning signs of the problem. Here are the most important things to notice. 

  •  Cracked Concrete 

First off, you need to pay attention to cracked concrete. When concrete has cracks in it, it’s typically because there’s an issue with the soil underneath. More than likely, you’re dealing with issues regarding soil problems underneath the concrete, which can lead to serious cracking problems overall. 

The reason that cracked concrete is so important to fix is mostly because of waterproofing problems. When there are cracks all the way through concrete, water can pass through it. That water can pool on top of the concrete, leaving ugly stains and weighing down the concrete as a whole. 

  • Concrete Sinking 

This tends to happen right before you have cracked concrete problems. If you’re noticing your concrete has started to sink in the middle, chances are that it is going to start cracking if you leave it for long enough. That’s because there’s usually a hole underneath the concrete, and if you leave it for long enough, you’re going to have the concrete start to crack because concrete can’t bend well. 

Additionally, pay attention to how the concrete is matching up with other concrete in the area. Have you noticed that the concrete slabs at one point matched up well with other concrete slabs nearby, but now they no longer match up properly? This could be an indication that you’re experiencing concrete shifting, which can be a big deal for concrete slabs.

What are the most common reasons for concrete driveway sinking? As with other concrete areas, there’s not just one response. There are a few reasons that can cause concrete driveway sinking, including all of these. 

  • Soil Erosion 

Soil erosion tends to be the biggest reason for sinking in concrete overall. When your concrete driveway has issues with the soil eroding underneath the concrete itself, you’re going to end up with plenty of problems. That soil erosion can come from several places, but it most commonly comes from rain and flooding around the area. 

Different types of soil will be at either a higher or lower risk for soil erosion. Expansive soils tend to be one of the types at a much higher risk. With expansive soil, the particles of the soil tend to move apart from each other due to rain or flooding. That can allow the soil particles to move away from the rest of the soil more easily. 

  • Improper Preparation or Usage 

It’s also possible to have issues with improper preparation in your concrete driveway. Essentially, the soil underneath the concrete needs a specific amount of preparation for it to work properly and hold up the concrete weight. If the people who initially poured the concrete don’t know how to prepare that concrete, it may not be ready to hold up the weight properly. 

Even if the preparation was accurate, you might run into a problem with too much weight on a concrete slab. This is especially prominent with concrete driveways. When you have a concrete driveway, you’re much more likely to have weight issues when you allow a car that’s heavy to rest on the driveway for many months without moving or driving it.

So how can you raise a concrete driveway most effectively? You’ll see a few suggestions thrown around for how to raise a concrete driveway. Here are some of your options. 

  • Problematic Answers 

Some homeowners might assume they just need to re-pour the entire concrete slab to make sure they can use it. Re-pouring an entire concrete slab may seem like the best answer, but it’s not. When you re-pour an entire slab, you have to wait for it to set and ensure that it’s solid enough. Additionally, if there are any problems underneath the slab, you run the risk of just having to handle these problems again in a few years. 

In the past, the most “traditional” method of raising concrete was through a process called slabjacking or mudjacking. These processes were beneficial when they were the only way to raise concrete, but nowadays many people recognize them for what they are: heavy, inefficient methods of halting concrete failure rather than actively raising the concrete. 

  • PolyRenewal™ Injection 

Today, most homeowners will use polyurethane foam injections rather than concrete slurry to raise concrete. Whereas concrete slurry is heavy, inefficient, and doesn’t raise the concrete, PolyRenewal™ is lightweight, simple to apply for an expert, and will lift the concrete back to its initial position. That’s why it’s becoming such a useful option for many homeowners with sunken concrete. There are ways to use PolyRenewal™ in both residential and commercial applications, which means you can lift sunken concrete no matter where you find it. Because it has a decades-long history with the Department of Transportation, you also don’t have to worry about whether or not it’s effective. You can be certain that it is.

Is it possible to just raise your concrete driveway on your own? Although the DIY mindset can be beneficial for some things, it’s not for others. Think about these important things when it comes to understanding how you can raise a concrete driveway. 

  • The Downfalls of DIY 

One of the biggest problems with DIY is the same reason it’s so popular. Essentially, DIY works well because you’re the one doing it. However, the problem with that is you’re not an expert. If you’re dealing with a scenario where you don’t need expertise, this is great. However, if you’re working with a scenario where you do need expertise, such as raising a concrete driveway, it can be a huge problem. 

A DIY solution for a sunken driveway is more likely to cause harm than it is to save you money. Whenever you’re dealing with a big problem like a sunken driveway, remember that a DIY solution is very likely to cost more money than an expert solution. With a DIY solution, you’ll typically have to go with an expert anyway.
