Thank you for creating this video. I am a retired teacher who just bought a little farm that needs some minor repairs. Most of the stuff I've never done, and I am so grateful for your help. Thanks again.

Use tape on both sides of joint prior to applying the self-leveling sealant if you want the job to turn out cleaner in the end.

Use foam pipe insulation with backer rod inserted to make it solid. If the gap is huge, use different size pool noodles.

I was just quoted $60,000 to redo my driveway and to fix the gaps in back of my house. I appreciate this video thank you very much!!!!

Twisting and doubling the backer rod is not a good solution. The rounded backer rod gives the sealant the proper profile to per form correctly . Also it needed to be wire brushed and primed. It also should be tooled both directions to insure a proper bond. I installed sealants professionally for 40 years and can’t remember how many times I have been called out to fix sealant a homeowner installed. It is not really difficult but there are basic things that need to be followed if you don’t want to replace the sealant every couple of years. With just a few improvements this would have been installed correctly. Get the right size backer rod, at least10-15 percent bigger than the joint. It has to be a very snug fit They make it all the way up to 4”.this is far more critical than most people think.As a professional if a tech rep from the manufacturer found the wrong size backer the warranty would be void. Wire brushing the sides of the joint is absolutely essential, we do it even on brand new concrete. And it only takes minutes. Finally every quality sealant ( like Sika) makes primers for their sealant and concrete. Use it. Just go to the manufacturer web site and find the data sheet for the sealant.Most sealants say something to the effect of “ no primer needed on most substrates” but if you take the time to read their product literature they all have primers and say to test adhesion first. Again one of the first things tech reps look for. Finally don’t use a water hose to clean the joint. The reason for not twisting or doubling the backer rod is that the optimum profile for sealant is an hourglass shape “) (“ Where the top and bottom of the diagram are the sides of the joint. Since the sealant is self leveling the top of the joint won’t be concave so it is critical that the bottom is.

Thank you! If i had known that there was a KZfaq video for everything before I got divorced I would have ditched Mr I don't know how way sooner than I did!

A side note for inexperienced caulkers. Make sure when you’re caulking concrete that you rough up (score) the concrete where the caulk will be before applying the caulk. This will help the caulk bond to the concrete. If the concrete is smooth or slick, there’s a good chance the caulk will peel off.

Thank you so much for creating this video! This idea is absolutely genius. Just purchased a home where the concrete walkway is splitting from the foundation and it was creating a lot of stress for me. I will definitely be implementing this to prevent any water damage! Definitely subscribed!

I used an old flexible garden hose. Worked great!

Thank you! Just bought my home and sealing the parameter is my number one project.

Good video. Glad you talked about backing rods before caulking. It keeps the correct shape of the sealant. Nice!

Great video and tops. I would tape the sides of the concrete and remove it after the job to give it a cleaner look. Looking forward to more tips.

This totally answered a question that 3 home depot guys couldn't. And shocker, they sent me home with the wrong stuff! I HAD a self leveling calk in my hand and they steered me to something different. UGH ! Miss the days when there were skilled tradesmen at the Depot. Thanks so much Hammers Home Reno!

I wish I had come accross this video before I hired a handyman who used concrete accross all the large foundation gap. This was the video I needed.

Fantastic and so helpful. I was in the process of paying someone to do a task I am more than capable of doing after watching this guy's video. Thanks

Great attitude and information. Being confident and humble at the same time is a skill few have. Oh ya the information is solid too.

Going to do this before it gets cold outside. Double up if the crack is big squeeze your caulk inside the crack. Let dry for 24 hours. Thanks for the tips!

Saved my basement, thanks a million.

Exactly what I needed. Gap between garage and sidewalk. Will do this today.👊👍

Dude, exactly what I needed. Didn't roll no doobies though. My mind already messed up. But like, really, appreciate it!

this is awesome.. I came looking for this exactly and it doesnt' cost an arm and a leg or my first born!! thanks sooo much.

Thank you.. I am currently lakhs miles away from your location.. Internet helped me to reach out.. Thank you for your idea.. It's worked out very cool.. I will post my video very soon to u

Thank you for your awesome advice!

Thanks so much! I was going to pay someone $400 to do this. I can definitely handle this.

Very cute when you can’t find your words. Thanks very helpful video.

Thanks bro, I’ve been having roaches just chilling in between here and nesting. I’ve always have to spray pesticide every couple of months. Now I can keep them out for good.

Thanks for the great demo. Helped me figure out how to tackle the gap between the concrete porch and house on my side garage door.

Thank you! This is what I was thinking of doing to my new house before the weather changes. I appreciate your honesty and the tips on how to do this. I’m not sure if my house needs it, but I’ve been around the building trades as long as I can remember, since we had builders, architects, and appraisers in my family. I’m always looking for potential problems that I can deal with myself. I’m a single woman in my 60’s, and I’m tiny! I need simple ideas! Thanks again! Does anyone have a video on sealing a basement window on the inside? It’s finished, but I see holes and bugs are everywhere!

Thank you handsome man! this was so helpful

I was thinking of using leveling cement and then calk over it. Not sure if I can find Backer Rod but that sure is cheaper. 50 lb bag of leveling cement is about $50. Thanks buddy.

Thanks for posting this. I also noticed your tattoo. I was in the 8th Division. Pretty cool.

I did this 2 years ago with Sikaflex. It doesn't hold up to concrete movement. If the concrete moves more than 1/8", which it probably will, then the sealant will break and leave a gap. It has very little stretch to it. I'm ripping mine out and putting in the rubber sealant strips

Can direct cement can be poured in gap. Like dry cement add water according to consistency.

Looks good

Dude I love your caduceus tattoo!! 🔥🔥🔥

Thank you, just what the Doctor ordered

For the larger gaps, consider using sand as a filter instead of backer rod. Way cheaper and you don't have those ridges from twisting the backer.

Thanks for the video. Now I know how to get the job done that's been an ongoing problem.

If you have a large gap, could you use spray foam? (ie. great stuff). Then go over with the caulk?

great video well explained.

Thanks buddy, this is very helpful. That's what I was in need.

A Structural engineer is the last book worm I would ask 😂

Thank you for sharing. It’s a big help.

You said caulk in hand. 😂 Thanks for the video...having this same problem.

Thank you, you answered all my questions.

Enjoyed the video keep up the hard work. Be blessed

Thank you for sharing this!

Very good method love your idea! I'm gonna do just that this weekend

Caulk in hand

Thank you sir for your very informative video! However, a very important step was missed here. On both surfaces inside the crack you need to apply a clear primer. This soaks into both surfaces and acts as two-sided tape. This is used to prevent the separation of the caulking. Good luck my friends!

Real genius to put a patio right next to the house.

This is very helpful. Thanks buddy.

as far as sealant concern, anything that is flexible, will last longer

Wow!! A man that will actually get up out of his lazy boy and fix something around the house!! Thank god he took video because this type of man is on the verge of extinction!!! 😆 LOL On a serious note i appreciate the tutorial it helps!

looks great I need to do this to my house

Thank you for the video it helps alot

That was helpful. Many thanks!

Genius! Thank you!

you have done termite treatment under concrete steps. I saw the 3-inch-away holes on your concrete, which were drilled for pouring termido SC into the soil under you steps

good video. You should put links to all the tools/items you used to fix it? So that its easier to identify at Home depot/Lowes.

I have this in gap between my house & cement walk way. Does it mean there is something wrong with the structure of the house/ foundation?

He said caulk in hand. Haha, thank you though, all jokes aside, this was a helpful start

Thank you for the video!

i need to do this on my back porch. thanks, for the video!!

Not the best presentation, but you get the idea and it works....GOOD JOB !!

Thanks for the video!

Just saw your video. Thanks! It’s been 4 years since uploading. Is it still holding up. Going to try this method

nice work buddy, next time try using a painters tape strip to get that straight edge!

How many tubes did you need? My crack looks similar in width and length, just trying to get an idea how much to buy....

I'll put sand on top of culk it gives a good look try it out

Thank you very very much man!! 👍🏻👍🏻👊🏻👊🏻

If the gap is too big, can you use a pool noodle?

This question is coming from the girl who had to KZfaq how to open a caulk tube. So far so good, but... How did you end up cleaning up the mess? I happen to have caulk on the concrete and the house.

Just found same situation in one side of my house, big gaps! Will went to buy something to repair it!

throw sand on this to blend it in , even if you messed a bit

Can I use hydronic quick stop cement instead?

About to start this project. My driveway is running on the long side of the foundation. I was thinking I would fill the crack with sand and then some small pebble rock then more sand yet no one seems to mention rock. Why is the backer rod better than rock?

Can you resurface over the caulk ? Only so it matches , if you are doing concrete resurfacing

I had 19 ft in length and 6ft wide sidewalk added to the side of my house. The contractor used rebar, but just mended the new sidewalk slab to my existing garage slab, which was built in 1967. This new sidewalk slab won't mend with my garage slab. Right? It looks like it did, but I am being told it will not.

My washroom is made of stucco and chicken wire and it was added on to the south side of a brick house. There's over an inch gap on the top between the brick and stucco and then coming down to the sides they taper down one side more than the other thought would this be the same concept as far as trying to patch it up? Cuz I have a real problem with my hands but it's up in the air it's not on the ground

Dude nice vid, you resemble keanu reeves 👍

Would this type of gap ie; between the pathway and the outside wall, cause damp? And if so would this method stop any further damp rising?

I have 2000 sq ft or so of giant baseboard gaps. I think this is the way to go. lol. Thx. But thx mainly bcuz I was stressing. Was so pissed off about it.

Which brand of self-levelling sealant is good? I've seen some from SIKA. It has to say self-levelling right? Great video - thanks.

Will this prevent water from seeping into my basement during huge storms? Are the materials for waterproofing or just aesthetic purposes?

How does this work in -40degrees Celsius

Will that hold water. I have a area by my front door concrete that butts up to my door so will that hold water

How did this hold up?

The gap I have isn't very deep, so should I skip using the backer rod?

Best way to clean it up? You mentuoned coming back to do some clean up. Best ways to get caulk off concrete?

Thank you

Thank you for the tips!

Great teaching guide

What lead you to seal this off??? Was water leaking into your basement?

Hello, If I want a sidewalk next to an XPS plinth, do I still have to leave a gap? Can I fill it with bitumen? Thanks

What do you do if the crack is so small it is hard to put backer rod in?

My gap is just above 1 inch. Can I still use this method?

I have a concrete block compartment built on a foundation that extends beyond the edges of the compartment. There are leaks and I am looking for a solution. since I don't have a gap as in your example, could I just put the sealant along the base at the side wall or is the product likely to flow and lie flat since you state that it is self levelling?

Thanks mate 🤙

Would this work for in-between stone tiles on a back porch area? Ours just have dirt between them and grow weeds no matter what we do.
