How To Repair a Crack in a Concrete Slab Floor

[@ahmedseyam4017]

How's it looking 5 years later? Still holding?

[@MiKa-fu2wi]

How's the crack holding up a year later? I may have missed it in the video, but what was the cause of your crack?

[@TheRealDogfart]

Don't use zinc plated threaded rod. Use 1/4" or 3/8" rebar. Also, don't use mortar to embed the tie rods; use the same epoxy compound you're going to use to seal the crack.

[@alexanderharo4550]

Watched this with my family, you are a life saver sir! We are going to definitely use this approach!

[@mariusd5913]

It can work i the foundations are stable, if it settled that way, but if you have expansive soil which cause this crack to move with the seasons then this may cause more damage as the crack cannot close again, if you keep filling cracks then the crack keeps pushing away with movement. I would first check the soil and foundations to ensure that slab is stabilized.

[@mariusd5913]

For example if you reinfoce the crack and make it super strong, any further movement of foundations will cause a new crack to form somewhere else where its weaker. Something has to give...The key is, stable foundations and soil.

[@AnitaBarneycastle]

​@@mariusd5913how can you have stable soil in a drought?

[@mariusd5913]

@@AnitaBarneycastle Its not about having stable soil it is about having a stable foundation. There a various methods from underpinning to water control such ensuring the soil remains dry around your house at all times. Damage is not cause by the conditions, but mostly due to the change in conditions.

Hi there can u give me the description of what kind of motor your using to fill in the cracks and stitching

[@victorvek5227]

Anchoring cement

[@jes587690]

Your repair job turned out amazing! Going to do this in my own basement floor. Thanks for sharing your how to video.

[@falsealarmno]

Not sure if those rods can withstand the pressure off that foundation movement.

[@SteveDab317]

if there is continuous movement, every little bit helps slow down the rate

[@Saywhatohno]

Amazing video!!! how big of a crack is worth fixing because basement floors usually have a bit minor cracks here and there? also please tell us what products you used?

[@ralphexwhyzee8168]

Can you please tell me what was the name brand of that compound you used to fill up the cracks? Thank you!

[@ericcasas7398]

ralph exwhyzee it's the home Depot stuff called Quick-crete.

[@howtohomerepair777]

Yes, Eric is right, it's Quickcrete Anchor Compound

[@MorticiaAttoms]

This is exactly what I have at my new house. The previous owner bought from someone that just slapped vinyl planking over it. I found it two days ago because we're doing all new floors.

[@devonmccormick690]

I had my closing today and started ripping up the old cheap laminate floors this evening and found a crack like the one showed in the video..I feel your pain. Did you come up with any solutions?

[@ricksmith7110]

Didn't watch the whole video, but you definitely do not have enough embedment into the slab even if you use the best epoxy, it will pop. Whenever we pin concrete or stone we always use stainless steel threaded rods. I hope your repair held up and thank you for your cool ideas

[@AmanSingh-wb5tp]

Is the track doing ok

[@two1968]

You only need 2 stitches for an entire room that size be doing stitches every few feet?

[@albertoabreus6230]

how the hell are you just going to embed that rod a few inches into the slab and then slop some quikrete over it?? that's not going to do anything. you're just pacifying the client and applying what amounts to a used band-aid to the issue. water is still going to seep up through the slab (provided there is no vapor barrier underneath) and it will completely ruin that patch over time, but the biggest issue is that the slab is blatantly settling!!! you even stated that one side of the crack is higher than the other. you need to pier the slab and/or apply fill to the area underneath the sinking portion of slab to mitigate the settlement. your method only conceals a much greater issue. anyone with $15 for a bag of quikrete and a bucket of water can do pretty much the same exact crap in this video. i promise that rinky dink little rod isn't going to do crap either. you need to dowel the entire slab in set increments (usually 24in or so, depending on structural design). you also need rebar, as it has braiding for the concrete to adhere to. the rod he used is smooth and concrete will NOT bond well to it. if anyone ever walked into my home and tried fixing a settling slab like that, i would throw them out prontoooooo. the method he detailed is ONLY good for minor expansion/contraction and stress cracks. the slab in this video is severely compromised and requires much more involved remediation methods. source: i do building inspections with a civil engineering firm.

[@briank8482]

Is foundation remediation covered by homeowners insurance? TIA

[@jesseparris6507]

Don't put tile over this without laying down a membrane; like Schluter's Ditra.

[@lorimerinombaeabrokerassoc9627]

How far apart should the stiches be?

[@sheliawilliams7887]

How much does this cost With labor?

[@genecarden780]

This is not the correct way to pin concrete. It needs to be near the center of the slab, at least 2” deep (impossible to do with. Mini grinder) the correct way to do it is to drill an angled hole aiming to have it pass through the crack near the center of the thickness of the slab. Fill the hole from the bottom up with structural epoxy gel then insert stainless steel rods making sure it forces epoxy out of the hole. Much easier and structurally far more sound. His stitches are far to close to the surface. Th3 surrounding concrete will break.

[@genecarden780]

@@tailgatecarpenter26 correctly pinning a concrete slab is a valid repair in a lot of cases.It very often can stop the crack from getting bigger ( stabilizing the crack,depending on the cause) by essentially placing rebar where it was missing. It is not going to help in all cases The way he did it has zero structural integrity.( I know you understand this but a lot of homeowners don’t) It’s funny you bring up fault lines. After the Loma Prieta earthquake we did a LOT of concrete and stone pinning and epoxy injection BTW 6X6 would never work maybe an lvl beam🤣🤣🤣

[@stevemaher3272]

We have lots of water in our basement... constant flow actually and they are saying it is the water table and water is coming up through the cracks, I can not even see some of the cracks. Would this work for me? Planning on gettin a sump pump soon as well. So upset, we just decided to sell our house and this happens.

[@rayzubi658]

How much does a job like the one you just did cost? I just need a ballpark figure.

[@99tercelpower]

1 million dollars

[@brewsterly2927]

Doesn't take the paper sticker off the endless thread?!

[@mannys9130]

It's called "all thread" and it doesn't matter too much, but you can take the sticker off if it satisfies your OCD. I definitely would myself.

[@pdkrace]

I would also like to know what you used for filling the crack. I have a big job ahead and really need to know.

[@ericcasas7398]

Mark McKinley looks like the home Depot stuff called Quick-crete.

[@howtohomerepair777]

It's Quickcrete Anchor Compound

[@grantjennings4743]

what is the purpose of stitching?

[@deborahbrancheau1373]

Our crack, I think, runs from our kitchen, through the living room and into the garage. The kitchen doesn't have any flooring but the living room has wood floors. Would I need to stitch in all three rooms? Or is the kitchen (and garage?) enough?

[@howtohomerepair777]

I suggest getting a free estimate from a structural repair company in your area. They will give you the specifics of what is recommended for your particular house. That's just my personal opinion as are all my tips, the final decision is up to you of course, hope that helps. Fix at your own risk, got to cover myself!

[@amigacherished5002]

use stainless steel stiches with a fibre glass bandage also pour an epoxy in the crack with the bandage on the top coated in epoxy also.kzbin.info/www/bejne/mJXdknSgirp0qsU

[@christophermoeller8221]

Hello. Where did you get the stitches? Thanks.

[@howtohomerepair777]

I got them at Lowe's, near the hardware supplies, there is a section of metal rods of different lengths and thicknesses.

[@ronfromtucson]

1/2" x 12" stainless steel rods?

[@howtohomerepair777]

You can just use wrought iron rods, that's what is used to reinforce concrete, it won't rust. 3/8" x 12" is what I used. Take your time, do a good job, good luck!

[@venictos]

Good job

[@oddopops1327]

👍👍😉

[@jackiepayne1902]

THANKYOU FOR sharing!!

[@jackwebster2348]

NFI! no guards, wrong steel, no dustless shrouds, wrong angle to use for cup stone

[@dizzyrooster]

Anchoring compound is not good for crack repairs. One year later, tell me how are the repairs?

[@impactajuvenile]

So what should he have used to repair that concrete crack instead?

[@azlandlord766]

that looks pretty easy

[@victorvek5227]

If you’ve gone that far; I don’t see why you didn’t etch and steel brush out the crack with a muriatic acid wash first. Then power wash out & brush in a bonding agent prior to the anchoring cement.

I need to do this to the garage
