I expect the crack will reappear because there is nothing of any strength holding together the two sides of the crack. Filling in like this only works if you first create a good bond between the two sides of the crack, typically with epoxy or with metal fasteners (I use 4mm diameter gr 304 stainless rod that won't rust and is cheap. Also, when you fill in the crack with mortar you need to first make the concrete quite damp so the mortar sticks to it and it helps to also apply a bonding agent (typically liquid) as well. Step one - open up the crack like in the video though you don't need smooth edges but in fact rough irregular edges are better because they aid bonding. Step two - brush or blow out crack to get rid of loose material. Step three - wet the concrete crack. Step four - while the concrete is still very damp but not wet, brush on a bonding agent. Step five - fill in the gap with mortar (cheaper to make your own with one part cement, three parts coarse sand, and two parts patching compound). When the mortar is still damp, brush like in the video and then sprinkle over it some sand of a shade that best matches the colour of the surrounding concrete (Reduces the white bleached look) or brush on a soupy mud mixture made from water and plain old dirt to make it look like old concrete. Optional Step 6 - to hide the repair completely, apply a concrete resurfacer to the entire concrete pad/path/ driveway or whatever, or paint it.
My builder did it like we see here in the video, i think it's pretty common because it's easy. Every single crack was back again within one season. These types of patches don't even last temporarily.
I'm thinking that you could have saved the dust and debris from the angle grinding to put on top of your patch, which would allow a better color match and blending to the original surface
That was my thought too. I’m going to use concrete to sprinkle on top and then lightly press it into the still wet patch material. I’m going to sift the concrete to remove large rocks first.
Correct…it’s the same it’s wood when you drill a hole save the sawdust and then mix it with glue, fill the gap with the sawdust job done can’t see the hole
The best is to use a crack chaser wheel in your 4” grinder. Then backer rod in the widen crack then self leveling Sika Flex joint compound. I’m a retired contractor and did many cracks that way.
Good video you did a good job I just have one suggestion that I do for blending in with old concrete whether it be cement to fill in a crack or that light gray caulk I'll usually let it dry to 50% dry and then smear black dirt on top of it and leave it to dry rest of the way and it pretty much Blends in with the rest of the cement. It was a tip I got from an old Mason works pretty well
I gotta say, the 45 degree angles were backwards...if you have the bottom of your repair area wider than the top, you don't get pop-outs from the freeze thaw cycle. If you're in an area that never freezes, it's not that big a deal, but in northern climates, you need to "keyway" your repair.
I like the Quikrete. I have watched some videos by an old school mason from Pennsylvania, Mike Haddock. He puts a mud slurry over his concrete patches to give it that used look.
I’ve tried many concrete fixes over the years. The best for cracks, for me, is Sashco products, Gray Slab which comes in a convenient tube for a caulking gun. IT STICKS, STRETCHES & STAYS.
Yes.. the dudes concrete cracked because concrete doesn't "stretch".. so the patch must Stretch, or it wil crack too. Thanks for the product tip... I have some repairs to do!!
Kintsugi...came to mind when the same thing happened to the concrete path...but with leveled river stones and pea gravel...kinda inspired by those river tables....maybe opening up those cracks to fill in with fun and treasure.
Thanks for the tutorial. It would be great to see the way it looks after full cure and a little wear on it. Personally if the crack repair remains quite visible then i would have gone ahead replaced a little larger panel for aesthetics. That is not a criticism just personal preference. Great video.
Every crack like that becomes an expansion joint that moves with thermal variations. So it is more convenient fixing it with a self levelling flexible compound, uness you cross stitch the two sides with pre-drilled dowels, and then you can use a rigid expansive mix.
I cut vertical sides along the crack. I can only go 1" deep with my grinder. I cut strips of 1" felt paper and put them in the crack. I mixed 1 part Portland with 2 parts sand to make mortar. i used the trowel to work mortar in on both sides of the felt paper. Fixing cracks in concrete is always temporary. The felt paper will allow for some expansion, which is why the crack formed in the first place. When it cracks again, it will likely follow the paper, rather than make a jagged mess.
Nice vid! I have added a little aggravate and sand to the top to match like an “art project”. I am not sure if that will ruin the integrity of the mortar? I use Dow Seal, but it’s expensive like $20 per sausage. Loved the tips on expansion joint vs. crack. That was super helpful bc I treated them the same. Your way creates a better line. I used a rotor hammer chisel that works well.
I used a chisel and made a1 to 2 inch GAP in my crack. I left the jagged edges and a lot was 45 degrees under. Then I used concrete bonding agent. Used paint brush and applied very liberally to all surface area inside the crack. Then I dry poured mortar into the crack. Tapped a hammer on both sides of the crack. I used a trowel to level, I used the mist setting on house and done. Applied water every hour for 4 hours. Came out perfect.
Good idea! I had a question to ask; wouldn't it be better to have the 45 degree angle a reverse 45 degree angle? That way it would be less likely to pop up; the 45 degree angle would hold the mortar in place. I appreciate your input and thanks for the video and idea! Blessings to you and your family, Kevin Barron
Thanks a lot your video. It”s very useful for me because there are a lot of cracks on my drive way, the same as you have exposed aggregate concrete. I see some people using pea gravel toon top surface so it can match to the rest.
Lots of good comments. As far as adding the ground up powder for a color match. I would say dampen it first. Drawing out too much moisture too quick as powder can do may cause cracking. Letting it cure in direct sunlight, especially on a hot day might not be such a good idea either. Rapid drying may cause cracks. Laying something over it to block the sun might be a good idea.
I'm just a lay person but my thinking is the crack is due to ground shifting. Where I live the soil is heavy clay. If I am correct the joint should have flex in it and because of that I would have used a silicone based filler. I like the idea of opening up the crack with angle grinder. Look forward to other comments
Exactly what I was thinking. By filling it with the inflexible mortar, I would think that the crack will just reappear. Perhaps an expansion joint would have prevented the crack from forming in the first place. But in this case, the crack also goes across the asphalt, so it is not due to simple expected expansion but from other forces like shifting ground or tree roots. I would have gone with the flexible concrete caulking. I would like to see a follow up video showing how the mortar patch holds up, or a video showing examples of how well both types of patches last.
How old was the crack? Years, months? The ground might have shifted and then settled. If it stopped settling, I think the mortar would work well. It would be nice to see a one-year update on this repair.
My driveway cracks were filled with the flexible guys and it shrunk and looks awful. Lasted about a year or less! I now am going to try exactly what this video suggests.
I’m in Italy and about to do a slightly wider gap early AM. Using instant cement at 92 degrees forecast in the afternoon. I’m ok with that drying temp?
I personally would use this for damaged concrete etc.. to fill cracks like this I would still use a flexible product like the " sica crack flex sealant " because that's most likely going to crack again with more movement unless you correct the root of the problem, the foundation underneath. Nothing against what is going on here, just me personally and how I personally feel about the situation. Great Video!
Use a power washer or chemical (bleach) to clean up accumulated algae on the concrete (that's why it looks dark). When you patch, the color will match better. Also, use a rough wet sponge to blend the sides into the existing concrete.
Hey my friend, I enjoy your videos and gave me pointers on certain projects. I do have a question with exterior wall seal and cement slab. Can you recommend a product that seals the transition between the bottom of an exterior stucco wall with the adjoining cement slab? I appreciate your help. Thanks.
Can a watery slurry of Portland cement be used at first so it can go deep down the crack? Then after it dries up, apply some kind of concrete sealent on top?
Thanks for the video, I have a huge crack on my driveway going horizontally, I wish you were near by to give me your opinion. I might try your method to close it.
I definitely think the first is better. Matches your driveway better and looks like just a one time application vs a two app. With the other. But Its funny that your video came up today because I'm actually getting ready to do my driveway.
Thank you so much for the meaningful comment my friend! Sikaflex will be good on expansion joints to allow flex, but for 150’ long fix I would with the quickrete my friend 🙏🏽😊 I wish you the best on your project! Email me if you need help on anything 👍🏽😊
@@thevoiceofthelordpastorkei7165 i hope you stayed with the sikaflex as you are repairing a crack,which was caused by the concrete and ground movement, hard concrete or patch will just crack again or come loose, the flex will stick and shrink and expand as needed
I have cracking on my drive way will this method work good for this? Or should I try another method. Please provide recommendations I plan on doing this in about 2 months
Do you have a solution for leveling my garage floor ? A number of years back I used to much pressure in power washing garage floor and etched a good number of areas and left a lot of areas very very rough… how do I cure that?
I’ve been looking for a video on best way to fix cracks on driveways. Your 2 days late and already used the Ready mix one and I think the mortar looks better. 😔
I would lean towards using the flexible stuff. That crack is there due to settling and if (big if) the settling continues over time it will crack again.
1) For safety, they make chisels with a protective ring near the top so you don't hit your hand with your hammer. Also, after I used the ready-mix product, I read the fine print closely. The last line in English stated that it should not be used where there is vehicular traffic, which would be a driveway.
On another vid you made for cracks, you used a "sand" type (1/2). To blend in the color to the surrounding area, couldn't you put some of that sand on top? It appeared to be multi-colored.
I’m about to fix several cracks but I wonder why people don’t sprinkle on a little bit concrete on the still wet patch to match the texture of the rest of the driveway. It would make the patch virtually disappear. Of course you’d want to remove the largest pieces of stone from the concrete before lightly pressing it into the still wet patch material. I also will be repairing a few expansion joints using rubber tubes and covering them with a liquid patch material. Once I Apple the liquid patch I’ll sprinkle sifted cement on the still wet patch material.
Rule 1 - concrete will crack if it has insufficient tooled and expansion joints. The purpose of tooled joints is to control the cracks, hoping they follow the joints. However, since your crack extends through the adjoining asphalt, the sub surface preparation/compaction is the likely culprit. Rule 2 - Crack repair only lasts through one or two freeze/thaw cycle(s). Also, the crack often returns in parallel adjoining areas, leaving a bigger crack to contend with. Check out what the pros do for tennis court cracks. The cracks always return. The sub-surface prep work was deficient.
Good video but if you don't want the crack to return take care of the actual problem. In this case when you showed the crack you showed us the problem too. Its that tree at the other end of the crack. The tree roots don't stop growing unless you grind the stump. So in summary, the repair you made will more than likely show up again.
I'm guessing when fully dried, it looked like what the edge looks like. My suggestion would be to wait a day, take an "After" video and include in the video before uploading.
In petrochemical industry, we require face shields for angle grinders, also. Too many people have had the wheel fly apart and had pieces go into their face.
I have to wonder what you think about sidewalk joints that are extra large. I just blew the dirt and grass out with the pressure washer but they are now fairly substantially sized.
I recently redid the caulking between pool coping stones and concrete deck surround. Also resealed the space between the coping stone and waterline tiles. These areas flex in the northeast freeze/thaw cycles with any water penetration. If expansion joint (or even large crack) use close cell backer rod and Sikaflex Concrete Fix No-Sag Concrete Crack Filler Repair Polyurethane Sealant. I have used the self-leveling version thinking it being more runny, it would adhere to the side walls better. Switched to no sag for vertical application. Self leveling version comes in gray or tan. No sag also comes in white. Tape off the seam with masking tape. Before it skins over, sprinkle on sand or any grindings you have if you created any in prep. Remove tape right after sanding and touch up whatever has pulled away. Let set for a day and dust off extra sand. In my case, I only sanded the horizontal repair. The area between tiles and coping stones were left white matching the tile grout. Sorry, I can't figure how to attach a picture.
Patch will pop out within 12 months as water intrudes and slab continues to move. Use urethane glue (resin) to seal the crack through the thickness of the concrete slab, and then top dress the cured glue. Even that will not last as there is probably a root or underground utility under the slab continuing under the blacktop.
One time I removed the guard from my angle grinder (Don't remember why I did that).Then I cut my finger in no time. Lesson learned. Never do that again under all circumstances.
Great video but if someone's got the ability to use an angle grinder I would have thought they'd have the ability to mix up some sand/cement mix themselves to fill the gap in. It's like filling the cracks in a wall - scrape it out to make it bigger and fill with filler then sand. Except in this instance you don't sand it, you brush it before it dries :)
Why is this guy pushing the grinder??? You have terrible control like that, and if it catches something, the grinder is going to jump right back in his direction, his arms and body.. Always use a grinder so it is pulling away from you, so if you lose control, it will go away from you and turn off out of your hands....

I think I would have sprayed a binder in the crack before putting in the concrete mix.Cement doesn't stick well to dry cement.
Good video but if you don't want the crack to return take care of the actual problem. In this case when you showed the crack you showed us the problem too. Its that tree at the other end of the crack. The tree roots don't stop growing unless you grind the stump. So in summary, the repair you made will more than likely show up again.
I'm guessing when fully dried, it looked like what the edge looks like.
My suggestion would be to wait a day, take an "After" video and include in the video before uploading.
In petrochemical industry, we require face shields for angle grinders, also. Too many people have had the wheel fly apart and had pieces go into their face.
Just open the garage door! Will make the job so much easier
I have to wonder what you think about sidewalk joints that are extra large. I just blew the dirt and grass out with the pressure washer but they are now fairly substantially sized.
Hi! Are they expansion joints or cracks? Could you send me a picture on my email? Fixthishouse1@yahoo.com
@@FixThisHouse Just expansion joints. -I would email, but I'm now away from that property, thanks though!
Proper prep and backing rod.
I recently redid the caulking between pool coping stones and concrete deck surround. Also resealed the space between the coping stone and waterline tiles. These areas flex in the northeast freeze/thaw cycles with any water penetration.
If expansion joint (or even large crack) use close cell backer rod and Sikaflex Concrete Fix No-Sag Concrete Crack Filler Repair Polyurethane Sealant. I have used the self-leveling version thinking it being more runny, it would adhere to the side walls better. Switched to no sag for vertical application. Self leveling version comes in gray or tan. No sag also comes in white.
Tape off the seam with masking tape. Before it skins over, sprinkle on sand or any grindings you have if you created any in prep. Remove tape right after sanding and touch up whatever has pulled away. Let set for a day and dust off extra sand. In my case, I only sanded the horizontal repair. The area between tiles and coping stones were left white matching the tile grout.
Sorry, I can't figure how to attach a picture.
I would have done different 😊
Patch will pop out within 12 months as water intrudes and slab continues to move. Use urethane glue (resin) to seal the crack through the thickness of the concrete slab, and then top dress the cured glue. Even that will not last as there is probably a root or underground utility under the slab continuing under the blacktop.
One time I removed the guard from my angle grinder (Don't remember why I did that).Then I cut my finger in no time. Lesson learned. Never do that again under all circumstances.
I’m glad you’re ok, but yes do not remove. They are there for a reason 👍🏽🙏🏽😊
It Cracked for a reason.. that patch will crack too, unless the patch material is compliant, mortar is not.
The cost 3.19 , 9 min.13 sec.to finish 😊.
For the life of me, I cant figure out why you didn't open the garage door and grind away like you did the rest of the grind?
Should have just put sand on top so it looks more like the weathered concrete
Great video but if someone's got the ability to use an angle grinder I would have thought they'd have the ability to mix up some sand/cement mix themselves to fill the gap in. It's like filling the cracks in a wall - scrape it out to make it bigger and fill with filler then sand. Except in this instance you don't sand it, you brush it before it dries :)

You should do a video on how to stop toilet tank sweating on the outside if you know.
Nice work, but definitely not how a professional does it
the job is good but the visual needs a little more work.
Pull the grinder down toward your body dont push the grinder up
Thank you for the safety tip 🙏🏽😊
Also have some water on hand to cool that blade, it'll will help the longevity of the blade and it makes it easier on you
What do you mean? I’m about to fix driveway cracks and I’m unsure what you mean about using the angle grinder. Thanks.
From Crack to the GRand Canyon ,
What he’s is using is for patch/repair, not for cracks that will continue to move. Need to use a concrete flexible caulk.
Missing most valuable info. Follow-up months later.
So it'll match a little better??? Why didn't you show that? It looks terrible.
It will crack again and again 😂😂
Why is this guy pushing the grinder??? You have terrible control like that, and if it catches something, the grinder is going to jump right back in his direction, his arms and body.. Always use a grinder so it is pulling away from you, so if you lose control, it will go away from you and turn off out of your hands....
