- Using @CajunCountryLivin ‘s DRY POUR technique for some crack repair on my existing old concrete slab. @MichaelBuilds also did some tutorials on this, so let’s see if it works. Follow along as I very loosely follow their guidelines and if this works, will be the easiest concrete repair I’ve ever done.

I think that is an expansion joint, you need those to be flexible because the ground expands and contracts with the weather and temps. I seal mine with rapid-set self-leveling polymer sealant from HD and throw some sand on top to help blend it in with the driveway. This way it keeps water out and stops erosion under the slab.
Dry pour.. yes! I needed this video thank you!
Why not simply pour out a pile from the bag and sweep it into the crack? Seems like you're doing it the hard way.
It's important to ask why the crack is there since it is an intentional crack. Ideally, you'd fill it in but ensure that the original control joint was replicated, so when it cracks open again, it goes where you want it to.
Fill with what? Should joint be made a little wider? He mentions it was an older house & had been filled with mortar first.
For those who know it's an expansion joint, please comment about what should have been done. I've seen something that looks like black tar. Does weather, temp, etc., make a difference in what to use?
Good job thanks. Is the mixture could you please confirm the portion ratio of the mixture
You should fill a control joint with caulk only to allow expansion
What kind of caulk?
I think you should have put in backer-rod (1”-3/4” depending on crack size) first. Then maybe Quikcret with added water (as directed). Smooth it out and let dry.
I am a total believer in dry pour, but isn't that an expansion joint you just filled?
Yep, I was thinking the same thing. Not a crack…it’s meant to be there for expansion. Yikes
What about for cracks in between cement steps outside?
Concrete shrink's does not expand.
@@peterloichtl4512 shrinking concrete? Interesting.
@peterloichtl4512 oh, in school I was taught heat causes things to expand and cold causes things to contract. I stand corrected.
You need expansion foam and top it with crack filler
Tearing the bag out of his way would make it easier to get the contents out of the bag
use concrete/mortar with extra adhesive already mixed in the bag. its like $30/bag but the joints wont crack in a year.
U just goofed
A dry pour for a small slab can work though not nearly as strong as a mixed pour but for crack repairs long-term I'd say it doesn't have a prayer, I'd give it less then a year. You get an A for trying to tackle it on your own but there are much better ways to fill cracks and/or expansion joints like that. Good luck with your home improvements and remember easy usually doesn't equal best.
Realistically, the concrete could probably use replaced anyways. I did this strictly out of curiosity, and I’m gonna bust some of it back out to see how it looks. That’ll be an upcoming video, documenting the process since this video was such a hit. Thanks for the insight.
I get where Ron is coming from, but people have to realize you used mortar. This will crack anyway under stress before the weather takes its toll on expansion and contracting from the ground. Should have used a flex sealant for that part.
Well, of course as two concrete slabs move over time almost anything will crack. Maybe Michael just needed to add a piece of the cardboard type material (I don’t know what it is called but have seen it on my wet concrete driveway) on one side of his dry pour vertically along crack and in crack. Thus, his mortar won’t crack while the slabs move vertically to each other over time or other changes.
Would any labeled flex sealant work?
@@bgwilke1670 yes
Hey bub if I got a 2 inch wide 4 ft long crack in my driveway just fill it with this cement and add sprayer water every hour for 6 times and then put a concrete sealer on it.
Shouldn't you have made the ditch wet first?
You didn’t wet it or use a bonding agent it won’t work…..
Contractors charge more than you want to pay so you your idea is looking pretty good to me I like this technique it’s a lot easier too I bet it will last as long as a professional would do Thanks for video.
Dude that's an expansion joint.
That is an expansion joint. The driveway and the garage slab always have an expansion joint and should not be cemented together. Seems like this guy's driveway had a lot of movement from settling and causing the expansion joint to over expand. I would have filled the joint with Elastomer. Filling the joint with cement will crack within a year.
Concrete does not expand it shrinks.
Won’t last long. That definitely is a expansion joint
Don't cut the paper off so you don't spill product..🤣
In general, dry pour is just a RUclips fad for a dumbass mind. It should not be used for slabs, steps, etc. But, there are a few instances where dry pour is okay. Apparently this has never been treated as an expansion joint, so if you're willing to do this every couple of years, okay. Even for this, when I'm essentially using it as grout, I would probably mix with water and use a grout bag to squeeze it into the space, then trowel or sponge it. It would be great for those gaps you had between rocks as well.
Open the bigger ya all
Errr this is NOT a crack, it is a EXPANSION JOINT...not to be filled Daaaaaaaaaaaa
Why didn't you fill the large crack that comes out from your new concrete line?
I did, just not in this video. Check out my channel for the other videos regarding the rest of the process.
You just filled a control joint.🤦🏾
I think this guy “flipped” the house I bought. Oof.
Cool process l Thanks for posting l.
U just filled a expansion joint . You are going to cause ur self all sorts of problems doing that
Dude you f’ed up bad! Why is this video still up? You have an ethical obligation to take this down! I just hope people are reading these comments.
Dry pours make for weak concrete..
Why put mortar and why in an expansion joint? This will not end good.
What is the solution?
Yea…..I don’t think you’re supposed to seal those up
Lol k
No offense, but come on, dude, you could have taped it off and just poured it in there and swept it in real nice.
Concrete vs mortar are two different applications and mixtures. Mortar is not recommended in this application, UNLESS is has polymers in it. Your title is misleading. Additionally, expansion joints need to be flexible.
This is a bad bad idea. A flex filler is tequired for expansion.
Please don’t do this, it’s not tied to concrete, it will crack again, I promise. You have to use something that allows for expansion
That's not a Crack, it is an expansion seam
Dry fill don't mean you shouldn't have wet and or put water in first. Your welcome
