Should You Use Rebar in a Concrete Driveway?

Durability and longevity are the two most important factors to consider when building a new driveway. However, it might be challenging to figure out precisely what kind of additional reinforcement a driveway needs, as the concrete itself is already one of the strongest materials you’ll find on today’s market. Still, sometimes making an extra effort could make your build much stronger.

You should use rebar in a concrete driveway to provide optimal durability and longevity. Rebar isn’t always necessary for smaller projects that won’t bear loads. However, some form of additional support is usually recommended.

In short, although using rebar isn’t always necessary or the best choice when pouring a concrete driveway, finding a reinforcement alternative that fits your project’s specifications is always an excellent way to make it as long-lasting as possible.

In the following sections, I’ll take you through the instances when adding this steel support system is necessary and how wire mesh can serve as an excellent support alternative for a concrete driveway.

When Is It Necessary To Use Rebar in a Concrete Driveway?

Rebar is reinforcement steel used to strengthen a concrete structure and support tension. I’ll dive more into its benefits in a moment. However, before discussing how rebar can make a driveway stronger, it’s essential to understand when rebar is necessary.

It is necessary to use rebar in a concrete driveway when it is at least 5 inches (12.7 cm) thick and must support heavy weights. Otherwise, adding the steel-based support system won’t be necessary. If unsure, you can always opt for a mesh wire alternative.

In cases where the concrete layer you’re pouring exceeds the 5 inches (12.7 cm) threshold, adding a sturdy support system is crucial to ensure its durability. 

Rebar and other similar alternatives can also provide your driveway with additional strength, which is essential, especially for a structure required to carry heavy vehicles on top of it.

Rebar will also be necessary for those instances where the concrete layer is poured on unstable ground, as it can provide your project with additional stability. 

Additionally, for those worried about the aesthetic aspect of their driveway, the incorporation of a steel support system might be non-negotiable. The rebar does an excellent job of preventing cracks and separations from appearing on the concrete’s surface.

However, if your driveway will only carry smaller vehicles or lighter equipment, investing in rebar support might be unnecessary.

Having said that, as long as the concrete pour is thick enough, you’ll always want to incorporate some form of substructure to help it maintain its shape and stability better.

The Value of Investing in Rebar Support for a Concrete Driveway

Using rebar in a concrete driveway is, without a doubt, a costly investment. 

However, the addition can save you money on maintenance and repairs in the long run, offering you a decent value for what it’s worth. Furthermore, concrete is already costly, which is why you should do your best to make it as permanent and durable as possible.

On the other hand, when it comes to smaller projects, you can always opt for a cheaper (and more accessible) wire mesh alternative, which I’ll delve more into in a moment.

Having said all this, if you’re wondering if you can cut some corners by using bricks or some type of durable scrap material to provide support for your driveway, I’d highly recommend not doing so.

This layout can create weak spots and pressure points on your build that could later cost you a fortune on repairs.

In short, although rebar isn’t always necessary for smaller-scale concrete projects, it can serve as a backup form of support. It gives you absolute peace of mind that if anything has gone wrong throughout the pouring and curing process, your paved entryway will still provide you with the strength and durability you need.

Types of Rebars

If deciding on whether you need rebar support or not wasn’t confusing enough, you’ll also have to choose the type of rebar that works best with your project’s specifications. 


However, there’s no need to worry, as in this section, I’ll quickly provide you with all the information you’ll need to make this decision.

  • Stainless Steel Rebar: This is the costliest option out of the three, which is why I wouldn’t recommend it for a typical concrete driveway that won’t hold any excessive weight. However, this alternative is solid and has the highest level of corrosion resistance.
  • Epoxy-Coated Rebar: Although less durable than the previous option, epoxy-coated rebar is much more affordable and usually a favorite among homeowners to use as a support for their driveways. Furthermore, the epoxy coating makes it another excellent corrosion-resistant alternative.
  • Sheet Rebar: This alternative is used mainly on floors and roofs due to its shape. However, depending on the shape and size of your project, you could technically implement them in your driveway as well. However, I’d still recommend sticking to one of the previous options (depending on your budget and needs).

What Happens if You Don’t Use Rebar in a Concrete Driveway?

I’ve now gone through the instances when using rebar in a concrete driveway is necessary, along with the value and advantages that this investment provides. However, those still skeptical might wonder how bad it can be if they don’t use any form of support for their concrete driveway.

If you don’t use rebar in a concrete driveway, the material will be much weaker, less stable, and more prone to cracks that occur due to excessive tension forces. Additionally, any existing cracks will be much more inclined to expand due to the lack of support.

As mentioned, as long as your concrete pour is 4 inches (10.16 cm) or less, your driveway is unlikely to face most of these issues even without additional support. 

However, in any other case, spending all that time and money building a concrete driveway only to leave it without a support system is simply a bad investment.

Rebar Alternative: Wire Mesh

Luckily, providing adequate support for your concrete driveway doesn’t have to be too challenging or expensive, as wire mesh is an excellent alternative for those looking to make their smaller-scale concrete projects more durable and long-lasting.

Due to its value and accessibility, wire mesh is quickly becoming a favorite among homeowners who still want to provide support to their concrete driveways without breaking the bank. 

Wire mesh instead of rebar for concrete driveway

The material comprises galvanized panels made out of welded wire that can support the weight of regularly-sized vehicles with no problems.

Furthermore, the wire mesh is highly adjustable to your project’s specifications, as it comes in different lengths, materials, shapes, and thicknesses.

Whether you should choose wire mesh or rebar as the support system for your driveway depends on your budget and the size of your project.

As long as you plan to use the paved entryway for regular day-to-day use that doesn’t involve any hefty machinery, wire mesh might offer you a better value.

If you’re still unsure how to find the ideal support system for your driveway, you can always combine the two alternatives to get the best of both worlds. 

To do so, you can use rebar around the outer edge of your concrete pour (which usually requires the most support) and choose wire mesh to fill the rest of your project’s perimeter.


Whether using rebar as a support system for your concrete driveway is the best choice for you depends on your project’s nature and size, as well as your budget.

If you need the highest amount of strength and durability for your concrete pour, investing in rebar could be worth it.

However, wire mesh is also an excellent alternative for smaller concrete projects. Additionally, you could always combine the two for a sturdy, yet budget-friendly, support system.
