The crack should be considered an expansion joint. Grind it out, clean it, backer rod then a flexible filler made for expansion joints. The slab will always move…
I have all the tool brands. That ryobi grinder I obtained reconditioned for 20 dollars as a backup 4 years later still works. I left it in the bed of my truck several times(rain and snow) and still works whenever I need it.
That’s an expansion crack due to no joints cut in it. Has nothing to do with base is NOT a structural issue, two separate slabs now that expand…this “fix” will not last…Period.
@@markme4 if I had done the job first day, there wouldn't have been a problem, and for time and a guaranteed fix, if I was to repair that, the first thing I would do is remove all the concrete and do the job correctly 👍🏼

yeah i get the sealer, accoustic type into the crack similar to the stuff they inject into the roadway cracks because it remains plyable, doesnt every dry completely, then patch over it. no matter what you do, the crack will always come back to hairline because the pad is moving, stablalize the pad is expensive this isnt the cistine chapel, best just to patch with grout non shrink slow setting ,to keep the hairline to a minimum. fast setting shrinks unless you get the special proprietary mixtures. regardless, slab is not stabalized. nice work, i guess. but this would have cost me 5 bucks worth of grout and some good masonry adhesive.
Everyone commenting on this being a patch job and it cracking again but nobody knows the situation without actually assessing it. If the crack was there as movement for a reason and that movement has stopped, doing this is perfectly fine. Hard filling or soft backer rod filling are two completely different solutions entirely dependent on what caused the crack in the first place. There isn’t a straight answer until you know the full story.
Concrete isn't my area of expertise, but I really have to pause for a moment when the crack is a solid half inch wide and extends across the entire building. Something ain't right. Just saying.
@@Billybob-go8hn maybe not it depends if the floor is still moving. If it is it will continue to crack it's that simple, this method cannot stop a foundation from moving
First off all I would want to know what caused a crack that lint and secondly IF it can be repaired it should be cut out and treated as an expansion joint
Good work, but a long thin 'patch' is not a 'repair'. Nothing done here helps make the slab intact again, and this is at best cosmetic, as there was no way to 'repair' under the wall. People mix up the words all the time, just make sure you understamd what your contractor is doing. In some cases the silica sand will seem to fill forever as the gravel base and vapour barrier below the slab has sunk away, and only the rebar grid is holding it together, and unless you fill that void movement will cause the crack to reappear. A repair would fill that void first (some sort of sprayfoam process normally which bears the weight and also insulates) and dramatically reduces the probability of needing to redo the patch. As always buyer beware.
From the wide angle shots looks like no expansion joints were used, zip strips etc. This crack is not from settling. Unfortunately too many unknowledgeable people here. The concrete made it's own expansion joint. If it was settling you would see elevation change from one side of the crack to the other. This is well within specs for a crack in concrete especially without expansion joints of some sort. But many are correct, it will crack again. In fact find me any concrete contractor that will guarantee that his concrete will not crack, and I'll show you a guy out of business in 6 months.
What have you really have a true foundation, crack, silica sand and that grinding is just a temporary fix that might be for minor cracks but if you have an actual foundation crack that went from one end of the foundation to the other, I did not suggest this because that is a temporary fix and if you’re selling the house, it’s better to go ahead and get it fixed and cut your losses when you’re ready to sell the house
I had the same exact problem on my old house. I found out that the problem was caused extensively from having the wall outlet covers not tight enough, they should have been tighter than that. Because they were loose, they were shaking from some occasional wind turbulence and that Rumbled through the floor and cracked the floor. It really bothered me for about 23 weeks and I finally had to get some cocaine to calm me down.

You’re fn joking right? 🤦🏽
Man finally someone who knows their stuff are you union ?
Seen unions do shitty work ... worked both sides no1 is perfect. But we both know which one pays better 😌
@@sas5177 🤡 😂
Bob does know…period.
Good 👍, but why not just pump the 2 part epoxy tube of goo into crack. It worked well for me
They make a rubberized epoxy that you can cut with a sharp floor scraper to avoid all that concrete grinding.
Sika
You can do that with this too. He just waited too long. I let it tack up, then use my scrapper.
Wear a respirator when handling silica sand, real bad for your health the particles you don't see in the air are the worst.
Totally true
He’s not joking

Did you buy it from some guy you met at the pub bet it,s stolen 😂
V blades are the way to grind cracks like that
You need to fix the problem that caused the crack....and it looks serious, once that is done....then you can look at sealing the cracks.
Yeah, settling is a big issue in building. We know.
@@qorpraltv5276 Shouldn’t be if there was a compaction test done first and of course if the Concrete work is done properly

You sold me on that 👍
My basement is full of them. Do I have to scrape out the cracks or just grout over everything as is?

Easy. It is new construction with poor base prep

Something ain't right. Just saying.
What good is that it's still going expand and contract
Exactly, joints were either on the wrong spot or none at all
That's a temporary measure unfortunately.
Had this technique done on my basement floor about 10 years ago and no movement yet.

Could you explain to me why the silica sand! Could one fill up everything with the caulking or is the silica required! Is this to save money!
The idea is to save on epoxy, also, if thick layers of caulk are applied at once, It may not cure -- the same may apply to epoxy.
First off all I would want to know what caused a crack that lint and secondly IF it can be repaired it should be cut out and treated as an expansion joint
I couldn't fit a 12' aluminum straight edge in my service van but this 4' level will accommodate.
It’s a slab on grade, it’s not structural, purely for looks
Is that repair permanent? Or will it come back after a year or two
Portland cement is our friend pals. People want to complicate everything!
Should’ve taken a grinder right down the center of that crack, and drop the concrete down an eighth of an inch to allow for more feathering…
Lay an epoxy / fiberglass cloth over for strength….. helps!!!

Just curious did you not have to cut the toe plate to fill in the crack under it ?
Naww bro if you can't see it ya fine😅
@@GamerXface Yeah but the termites can
Is that silica sand the same stuff we use for interlocking pavers?
Ты че творишь кто так делает
Customers don’t always want the structural repairs. Sometimes they only want the band aids due to the price points
This isn’t the case. This is new construction with a poor base prep
If your house cracks like this, you got a bigger problem than that
Nope
That adds strength to the foundation
Problems not on top it's underneath
Safety is a non issue here, lol
Exelente trabajo ... Un poco de vibrado para que la arena sílica penetre ...
What is that product call i cant find the same exact one
Tell everyone who the builder was, so we don't hire them!!!!!!
This is all builders in the Central Florida area!
It turns yellow but works ok. If you put sand on top for the camouflage
How did that size crack happen, then again just grind it fill it sell it on , without sorting the cors .
You need to do what WiFi Systems says. For example; extended dry periods will cause concrete slabs to crack. Large enough for you to fall into them.
Why does cement crack like that?
What is that u r filling in cracks

I used some of that stuff for a mountain here in California after the earthquake
Best stuff I use is tooth paste stuff gets rock hard when it drys
Good smooth concrete
That 8s a Mike mouse solution 😳

2 part polyurea plus carbon fiber filament which are embedded perpendicular to the Crack
Those are some serious cracks
Great repair! but please put on a proper mask.
Still gonna crack
Epoxy
more easy putting dilatation, where the architect planned
Apuesto a que en menos de un año la raja volvera a salir...
You know their own professional when you’re using Ryobi tools
Argamassa AC3 resolve é garantido!
nice.
Soma flex and done.
What tool is that?
Angle grinder with concrete blade
It will open again!
Need to saw cut it open and epoxy in rebar perpendicularly, then pour
Why the silica sand? Why not just fill the gap with the epoxy?
👍👍👍👍
and what you did? ghis will crack again in no time. concrete floor has to be made of interupted pieces
Cracks over an 1/8" are an actual structural issue, you don't just patch them over with some BS.
Ohh,,hail nooooo😮,,not a correct professional repair,,especially anyone who uses quickcrete scrap 😂
We're can I perchance this product
Hello, I believe I purchased it at a home depot. Thanks for watching 🤙
Como un pro
It's still a crack
Complete waste if time. Silicon would have given same result
The question is "what caused the crack?"
Bela maquiagem...😅
Still looks like a patch job.
That came out surprisingly well great work😊
Nice man
Thank you 🙏
Tear out replace time will just make it worst that a cheap fix
Залепить красиво можно, но не надолго
This is a bandaid really.
En un tiempo más se volverá a agrietar pésimo trabajo
That looks much worse than the crack did
An entire crack from side to side something seriously is going wrong a little filler wont cure..
Quedo bien culero
Это не поможет, когда плита фундамента треснула пополам.
Wouldn't you Wana do the repair b4 putting walls up? That would have been the right way
😂 like putting bandage on gunshot
Purdy
Wouldn't mortar last just as long and be a lot easier? Plus neater after cleanup with a sponge
And then what?
Investigate ..
if you want to teach something but show safety first.
What you did, was absolutely pointless
Crack chaser
that's mask ain't helping with epoxy fumes
Nothing really fixed there
Make up on dead body.

All that to laid down tile on that floor a waste of time and money
