Learn how to replace a segment of sidewalk with this DIY Sidewalk Repair Video. In this Video, you will learn how to remove and demolish the existing sidewalk, how to prepare the sidewalk subbase, how to mix and pour the new concrete, and how to finish the concrete sidewalk with rounded concrete edges, control joints, and a concrete broom finish.
To Replace a cracked or damaged segment of sidewalk, start by removing the old sidewalk. Excavate and compact the soil as needed and add apply a ~4” gravel subbase beneath the sidewalk area. Next, use lumber to “form” the sides of the sidewalk and apply concrete to the sidewalk area. Screed the concrete surface to get a uniform layer and then finish the sidewalk concrete surface using a hand trowel and edging trowel. Apply a broom-finish to the concrete surface and add control joints as needed. Finally allow the concrete sidewalk to cure.
Specifically, video will focus on how to replace a damaged section of concrete sidewalk at the end of a driveway.

Below are the step by step instructions for how to Replace a Segment of Concrete Sidewalk:
1. Plan out your Sidewalk Project
Before you can pour a concrete sidewalk, you will need to spend some time planning out the project. Things you will need to think about before starting the project are:
- How much concrete will you need to replace the segment of sidewalk?
- How thick will the concrete sidewalk be?
- Will a gravel subbase be used?
2. Demolish and Remove the Existing Concrete Sidewalk
The first step in replacing a damaged segment of concrete sidewalk is to remove the existing sidewalk. To remove an existing sidewalk, it is recommended that you rent a jackhammer from your local big box store so that you can break up the concrete into smaller, more manageable chunks. Additionally, use a concrete saw or an angle grinder to cut a control line in the concrete. This will allow you to use the jackhammer to remove a clean, straight line in the concrete.
3. Excavate the New Sidewalk Area as Needed
For most new sidewalks, I recommend that you excavate approximately 8” below grade. This will allow for a four inch gravel sub-base and four inches of sidewalk concrete thickness. Compact the soil using a hand tamp or mechanical compactor.
4. Apply a Gravel Subbase to the Sidewalk Area
After compacting the soil, you will want to apply approximately 4” of a gravel subbase to the excavated area. Typically, No. 57 stone is used for the gravel subbase.
5. Construct Your Concrete Forms and Position Them in Place
After applying gravel to your new concrete sidewalk area, you will want to construct the concrete “forms” for your sidewalk. Concrete “forms” are simply the frame/perimeter for your sidewalk. To construct the forms, it is recommended that you use 2”x4” lumber. If you are replacing a curved section of sidewalk, you will need to use a flexible form material.
6. Reinforce the Concrete sidewalk (if necessary)
Consider using steel “rebar” or steel wire mesh to the concrete to give it additional strength and to help prevent it from cracking.
7. Apply Concrete to the Concrete Sidewalk Application Area
At this stage, simply mix up the concrete (or get it delivered via concrete truck) and fill up the entire sidewalk form area with concrete.
8. Finish the Concrete
After applying concrete to the sidewalk form area, you will need to “finish” the concrete. Start by using a straight piece of lumber to screed the surface of the concrete. Then, use a finishing trowel, edging trowel, etc. to finish the surface of the concrete. Give the Concrete Sidewalk a "Broom Finish" if desired.
9. Finishing Touches
Lastly, remove the forms and enjoy your new concrete sidewalk!

As a retired mason I would like to say that you should have replaced the apron while you were doing it because it was broken also. The reason your sidewalk was broken up is that it’s to thin for the application, it’s a driveway and should be a full six inches thick for both the sidewalk and the apron. I’m not sure what state you’re in but most states (and cities for the most part) spec out six inches in a driveway area. It seems that a lot of your viewers think that the city should replace that broken concrete, but if you would look into it you’d find that homeowners own to the center of the road and they have an easement from the center of the road over usually 25-30 feet and is probably right to the back of the sidewalk (the side closest to the house). You are required by city law to maintain the sidewalk on your own property, and any street repairs or replacement is usually assessed to your property taxes. It’s pretty much the same everywhere so it’s just part of owning property in town.

It varies from area to area. In our town he wouldn't be allowed to replace that sidewalk. Our town owns and takes care of right of way. Usually 50-60 feet. So 25-30 feet from center of road.
Looks amazing. Didn't know I'd like this kinda stuff but I do

Just a note to this. If you are putting mesh in for keeping concrete from cracking. It is always best to keep it in top 1/3 of the the concrete pour. If you push it down to the bottom like they did in this video it doesnt do much for cracks on top of the slab. Other than that great job.

“Push it down to the bottom”? He literally explained he laid 2 inches of the 4 inch slab and then placed the mesh. Your 1/3rd still holds but I don’t think it’s “at the bottom.” Anyway, just saying…
I need my walkway and a step repaired. Thanks for the tip. Will have to hire someone to do it. Great video!
Great. I need to replace some of my sidewalk and I’ve never done concrete work so I’ll be jumping in like you if I do it and just going for it.

Interesting, I always assumed that fixing a single lane sidewalk like that would fall on the city - because it would be outside the property line. Just googled myself and - it turns out that the city doesn’t care and actually requires the property owner to take care of it. Boy…glad taxes go somewhere 😂

I actually called the city to see if they could replace it since it looked like a lot of other segments had already been replaced. BUT it turns out the the segment on front of your driveway falls on you unfortunately 😅. Thanks for watching!

That turned out great! Now all you have to do to make the apron uniform is tear up the apron and poor some new concrete. LOL Probably not in any future plans, right? Keep up the good work Andrew.

You can power wash the extra concrete off the apron after the new concrete has fully set; probably a better result than power washing while the new concrete is still wet. The poor bond and thin layer should pop right off.

Or small area like that, just tape plastic down along the edge and cover the apron. Especially if it's nice to begin with. Not the case here. Hahaha
Or you could make your concrete a little dryer and use Masonite for your edges so you don't have to worry about the wind blowing plastic away.
How big was this slab man? Great content! 👋🏽👋🏽

So what about when you pulled out the 2x4 , is there a gap left between the two edges of concrete a nd the existing driveway? You didn't say anything about that?
Did you have to get permit to do that?
The reason for the sub-base is if water freezes in the ground under your walkway it will expand break your walk way.

Oh my goodness! Where to start? I forgive you reiterating your lack of patience about setting concrete; I mean how often do you get to make your own sidewalk, especially since you own your own jack hammer and concrete maker, right! As for the stains, perhaps mix a slurry of concrete mix with water - a weak solution and 'wash' the old concrete surface with it - might make it match. As for the back-breaking work; that job would have ended me for sure, but you mentioned B. was in school for PAs (physicians Asst) and I'm sure he does not want you to get hurt, but would probably jump right in for a chance to practice on a real case :) :) ! Seriously, you guys heavy lifted lots more fixing that house up to be bothered with a little jack hammer job. I forgot that the GOP is running MD so I can see why citizens have to fix their own municipal problems! You should ask just where your city taxes are spent! Id like to know (too). Andrew this was great job and I am excited for the next challenge in your future. Take care. Best to all.❤

Haha I totally agree! I feel like the City should WANT to do that work to ensure that everything is uniform and done correctly. 🤷🏼♂️ oh well.. at least it was some more concrete practice that I desperately need. Thanks for the support, Patrick!
Was sealing not necessary, every patch of sidewalk I see replaced gets sprayed with some kid of seal but maybe it’s dependent on season/geographic location.

A lot of the extra are to deal with freezing as water expanding is the number one cause of ruined concrete. Well that and tree roots.
Can’t you just use an angle grinder and grind off the spillover concrete
Is there a cheaper way to DIY for complete dummies with no experience, and without using a jackhammer at all. Im a woman in my 40s now. I can’t handle a jackhammer as most women can’t lol. Any advice for me?
Too thin not code too wet to broom ..💩😉
Back in the day when we had functional city governments and maintenance program the city would fix it. Now I need to watch KZread video and go to Lowe’s and get it done myself and they still increase our taxes.

In my city they lost a court case in 2009 where they were supposed to fix the sidewalks because they weren't ADA compliant. The city tried to claim no responsibility or ownership of the sidewalks because somewhere in the code they had written that homeowners are responsible for repairing sidewalks, but they still have to get permits from the city, make it uniform with the city's sidewalks, etc. Anyway, it's 2023 now and today sidewalks are worse than ever. 😅 I'm thinking about doing my own, but I'm worried the city will stick their nose in my business and fine me for fixing "my" sidewalk.
