Fast-Set Polyurethane Concrete Crack Injection In a Basement Wall 

I just finished using this system. I had a crack from floor to ceiling and it traveled between 2 joist bays. They say removing studs is not required, I would do it. Otherwise, you will get leaks when you inject the Hydra Stop. Everything worked exactly like this video shows without a single issue. When injecting the Hydra Stop it does get a little messy, make sure you have the plastic down on the floor for that step. Also make sure your plugs are in all the way! The Hydra Stop will continue to expand well-after you are done and can push the plug out if it's not all the way in. Happened to me and luckily I was standing right there. I replaced it and tapped them all with a hammer to make sure they were all the way in. We'll see how well it works, but I feel confident that it penetrated the entire crack. So far, I recommend.

I used used this product during the early part of fall 2018. As of Jan. 3 2019, no water has gotten in. Worked perfectly.

Great video and comments. Been waterproofing basements walls for years and never repaired concrete walls like this. Best stuff use it

I did the same thing with bondo and plastic straws cut to 1" lengths and held in place with toothpicks in the crack while the bondo hardens around the straws. The straws are 6" apart. Use cement crack filler tube from Lowe's in an ordinary caulk gun, inserted into each straw, Go from bottom to top of crack. Finish with 6 coats UGL waterproof paint. Been leak tight for 11 years now

I bought this product.i also tested epoxy with waterproof foam. 8years later, same results. The s1E did get a small seep 3 months ago. Did the epoxy coat inside and injected that great stuff waterproof, so far so good. And it was cheaper. Since from what I’m reading this has a 10-20 year life. I will polyurethane seal the out side of crack. I was looking for a permanent seal when I purchased. O well

Had this done 10 years ago. Just starting to re-leak. They are coming back next week to see if they can repair it.

You should do a new updated process review. I just ordered today. Looks good to me.

I just did this on a very narrow crack that did leak a lot of water and I'm just waiting for it to rain. The only issues I had was injecting water into that narrow crack. It would just run out. So what i did was just inject the water with my mouth using a a little pressure. That worked well and I could judge how much water I injected. Maybe if the water bottle had a 90 degree tube it would work better. Waiting to see if I'm successful because if I get 2 inches or more of rain in a short time I get lots of water in my basement. Grrrrr.

Well done, video would be a good learning tool for anyone trying it yourself. Thanks, for the help

Do you need to make a v-groove (using a chisel or power tool) if the crack is a hairline crack?

I highly recommend that you put the bottom port as close to the bottom as possible, not 6-inches up as in the video.

It's a great video. I know this method, it 's easy to fix rather than outside this foundation. Thanks.

Anyone know where I can get this stuff nowadays, or something similar? I've checked the usual places and stores. Most carry the sika brand caulk like sealers, but not the injection kits.

Thanks, great job & nice clear video

I used this method but the resin never came to the upper injection port. I guess it went straight through the crack. Any suggestions?

Hi.. thanks for the video... Question: why we inject the water, isn't the water will stay and prevent the sealant from flowing??? and how long after the water we can inject the sealant??

My question is if this is already installed and after a few years they leak to do you fix , is there a video on this thanks

what happens if water never flows through to the lower port?

I'm looking for the technic to seal inside corner wall, any knows any videos or other infos ? This corner is in fact an old basement that has been extended so it is not a real crack but a joint between an old and a newer wall (done over 20 years ago), there was metal bracket, sealant and waterproofing from the outside but is probably worn from the time... the only technic i'm finding on the internet is cracks on a flat wall... do you think i will have to seal the corner joint and drill at 45 degrees and use thoses holes for the plugs ?

Will this work with rock foundations as well ????

Should I use a Chisel or an angle Grinder like suggested in other videos to open the crack?

Ty THAT WAS VERY HELPFUL

My crack was repaired this way by reopened

How would this work on a crack where concrete wall meets concrete floor?

I've flipped over 500 houses in the last 17 years and have used this and similar products on at least 20 houses. It's simple and I teach my renovation crews how to do it. As long as the wall is structurally sound, this is a permanent and effective method to repair cracks and prevent water intrusion from them. Follow the directions EXACTLY or the results will fail. On a poured concrete wall, this will protect the rebar inside the wall to keep the foundation structurally sound. I don't think this would work on a hollow concrete block wall and have never attempted it.

I have a rock pocket that sits in between pours that is leaking. Would this be able to fill that in, or is it too rough?

So how do you clean floors got some on my floors

What do you do if the crack is ok exterior ?

would this work on a garage interior wall crack that extends to exterior with stucco on interior/exterior over cement block

In what application would you use foam over epoxy? Does it merely come down to costs or does foam have an advantage over epoxy? I am considering expoxy for my basement wall cracks that are minor (less than 1/2" side)

After the resin cures and dries, can the paste and ports be removed from the wall with a putty knife or something like that or would that negate the whole process? And if they can, is it hard to do/leave a lot of residue on the wall?

It worked!

So use Flexseal.. if it's wet.. it won't matter

Should I seal crack with proxy paste from the outside first no minimize the oozing out of polyurethane?

How does this penetrate the crack by sitting flush against it? This seems like it just seals the surface. You need to drill the crack, this system is whack.

Can the epoxy paste be removed along with the plugs after the repair has dried?

why not mix an elastic solution in the concrete when you build the house ?

4:44 drop of water from the outlet ....

How do you do this for a crack in the floor?, start anywhere? at one end, etc?

I odered the ten foot Crack repair kit from a dew weeks ago The one I rdered is not for leaking Crack I ordered the one to strengthen the Crack I see in this video you say to add water first with a squirt bottle Do I need to do that also? Or is that only for a different epoxy?

fantastic

how do you get the corners?

My basement wall was previously sealed with tar the cracks re emerged and water is leaking again can I put the epoxy over the tar or should da tar be scraped off or somehow remove before the epoxy and ports are put on?

I’m installing an outdoor boiler system and will be cutting a 4 inch hole in my foundation to put a 4 inch corrugated pipe through that carries my waterlines. I will have a little gap around the pipe. This should still get the job done wouldn’t you think? I plan to cut the hole just big enough to put the pipe through.

Can this be used in a basement concrete wall around a water pipe that enters the house. I had the main line repaired, but the when it rains I get water in around the pipe.

Does it work for brick wall?

What is the best way to dry the crack out before starting the repair?

Why not inject from the outside as well?

are this materials available here in the Philippines..thanks

Is the product available in india.

Hi, the kit looks good! Would this kit apply if I just have cracks but no water penetration? Will your epoxy keep the crack from spreading further? Thanks!

So is this product used to stop water leaks or strengthen the wall, or both? My basement is dry but I have older cracks which I want to seal with an epoxy or something that will help strengthen the wall. Any suggestions?

Do you ship to Canada?

Where can I buy the product you used in the video?

my leaks in the corners how do i do this???

what if the water doesn't flow to the next port and that next port is clear from the epoxy 300?

How do we do this for horizontal cracks?

so this isn't a fix for integrity but water proofing?

There is one KEY FACTOR that is not mentioned in this video. You should determine what caused the crack. If you don't the crack may expand and leak again. Cracks are an indication of a potentially significant structural problem.

This should be called repairing your crack.

Can I go to Home Depot and buy it

Were do I buy it what's it called

I am not grinding the ports down why the hell can't they just be removed before everything dries damn

Why was water injected before the polyurethane?

I found a quick and easy way to fix a crack in my cellar wall. I used a hot glue gun and it worked like a champ. It is quick and easy to do and if you need to buy a hot glue gun they are cheap and good to have around.

The slow-motion is unnecessary and delays my understanding

🖒🖒🖒

Epoxy doesn't stop water leaks. Epoxy is used for structural repair. I really hope you guys don't waterproof like this. if you do please tell me where your located so i can come take all your business. Leave waterproofing to the professionals

Seems to take too long and way too much work. I have seen better methods.

Is this safe to use around a PVC sewer pipe in my basement?

News papers? What are those?
