The concrete demo process is a simple, straightforward process IF you know how to do it right.
Breaking up concrete yourself can save you a bunch of money, but it can also be backbreaking work. Plus, if you’re hiring a contractor to pour new concrete, handling the demolition yourself might actually wind up costing you more in disposal fees.
Our concrete removal guide will help you decide which route is best for you—doing it yourself or hiring a contractor. Keep reading to learn more.
Should I repair or remove the concrete?
First things first—deciding which approach is best for addressing your concrete project.
Generally, complete concrete removal is your best option if any of the following are occurring on your driveway, patio, sidewalk, or slab:
- Multiple cracks - wide and deep cracks that are uneven/settled on one side
- Frost heave - part of the concrete is pushed up due to the frost that occurs in colder climates
- Settled concrete - caused by the sub-grade's improper preparation
Simply repairing the concrete may be the more cost-effective and faster option in these situations:
- Thin cracks - small, hairline cracks with no evidence of settling
- Sunken concrete - caused by heavy equipment or load (e.g., a heavy dumpster) that was placed on the concrete
The video below does a good job of explaining the issues that arise with resurfacing patios, sidewalks, and driveways.
How much does it cost to have a contractor remove my concrete?
The cost to remove concrete varies by:
- the amount of concrete that needs to be removed
- disposal fees
- your location
Money $aving Tip: If contractors in your area are able to haul the concrete to a recycler, you can save a significant amount of money by no longer having to pay "per ton" dump fees at the landfill.
Here are a few examples of professionally done concrete removal prices:
- A modest patio or sidewalk (200 sq ft) costs $400 - $600 in some parts of the country. However, the cost can be significantly more if the concrete cannot be recycled.
- A typical two-car driveway costs $1,500 - $2,500 and up, but this is highly dependent on the size of the driveway. Also, if the driveway was completed with reinforced concrete, it's more difficult to remove and the cost to remove it will likely go up.
- A concrete foundation generally costs $2000 - $5000.
How do contractors demolish and remove concrete?
There are many tools that concrete demolition contractors can use to remove concrete. Here are two of the most commonly used tools...
- A Bobcat equipped with a hydraulic or pneumatic breaker attachment (as seen in the top right picture)
- Another common tool is a jack hammer (as seen in the bottom left picture)
Usually, the contractor will also bring a roll-off dumpster to the site. Once the concrete is broken, the Bobcat loads it into the dumpster and hauls it away to a landfill or concrete recycler.
What tools would I need to demolish concrete myself?
There's more than one way to break concrete, and if you're a beginner, choosing the right tool for the job might seem a bit overwhelming.
Here's a breakdown of two inexpensive tools that can be used for manually demolishing small sections of concrete:
This is the go-to concrete breaking tool for most do-it-yourselfers. A 12 lb. sledge hammer might not seem like much, but it can go a long way.
If your concrete is 4 inches thick (very common) or less and doesn't cover a large area, try a sledge before renting heavier equipment.
You'll know pretty quickly whether or not you'll need something with more power.
Quite a bit of equipment falls under the umbrella term "jack hammer," which is essentially a pneumatic hammer (i.e. it's operated by air).
These tools, and the air compressors that power them, come in all shapes and sizes.
Even the drill bits on the end are interchangeable—wide chisels, narrow chisels, pointed chisels, etc.
In addition to the tools needed to break the concrete, you'll also need other safety and disposal tools, including but not limited to:
- Safety equipment - This includes the basics, like safety goggles, work gloves, and sturdy boots (steel toe is best). You'll also want to use a respirator to prevent unsafe inhallation of cement dust.
- Plastic sheeting - A thin sheet of plastic (6 mil polyethylene typically works well) is great for containing dust and keeping pieces of concrete from flying everywhere.
- Pry bar or shovel - If you're lucky enough to have another person helping you, a pry bar or other prying tool, like a shovel, can be used to pry up the concrete slabs while the other breaks the concrete. This makes demo much easier because the slab absorbs the energy of each blow rather than the sand or gravel base underneath it.
Can demolished concrete be recycled?
Yes. Most metro areas have a recycling facility where you can take your concrete, keeping it out of the landfill. Find out if there's one near you.
Concrete recyclers crush the concrete and reuse it as an aggregate in new cement.
If you're demolishing the concrete yourself, renting a dumpster will likely be your best bet for recycling/disposing of the concrete.
