The Best Way To Fix A Leak 
In A Basement Wall

If you're basement walls leak when it rains, the solution is to use a 2-Part polyurethane foam injection kit to repair the cracks and prevent water from seeping into your basement.

"This page will show you how to fix a basement wall leak from the inside"

Hi, I'm Mike Day, that's me repairing a leaking basement wall in the video above.

If you're basement wall leaks from the inside like this one did before I repaired it, I want to show you how to seal the crack and stop water from coming through it.

I want the CRACK REPAIR KIT now.

The basic steps for fixing a basement wall leak

The basic step by step formula I use is below:

  1. Clean the outside area of the crack and wall
  2. Paste on the injection ports every 8"
  3. Seal the outside of the crack with the epoxy material
  4. Inject into the bottom port first to start filling the crack
  5. Continue injecting into each port as they fill the crack from bottom to top
  6. Wait 24 hours and remove ports

Fixing a crack in your foundation wall can seem like a very challenging task to take on.

Especially if you don't know what kind of crack repair material to use.

Even more confusing is not knowing where to start, even if you already have the right crack repair kit!

If you're going to fix this crack yourself and you've never done it before, you need someone who can help guide you through the process...

Someone like a professional who is with you every step of the way to make sure you succeed.

Basement wall crack repair: do-it-yourself or not?

I made this video showing you how to fix a leak in your basement wall so you can determine whether or not you can do this yourself or if you have to hire a professional like me.

p.s. "I usually charge $500 dollars per crack to fix these"

I think you can, but why do you need to get that cracked sealed up asap:

  • It's possible your basement could flood
  • If the floor gets wet, there's a good chance anything setting on the floor could get ruined.
  • Or worse, a wet basement could lead to mold, fungus, and mildew growth that would cost you thousands to get rid of.

This is my "diy crack repair secret weapon"

That's me injecting the crack with a repair material that fills the crack and expands 20X to completely seal the crack and keep the water out.

My company, Day's Concrete Floors, Inc. does foundation crack injection as one of our services to our customers.

I can tell you that I have to charge upwards of 500 dollars per crack to fix these leaking cracks.

I know, that's a lot of money!

I'm a business, I have material costs, labor costs, overhead costs, and I still have to make some profit on top of all that to stay in business.

I've been doing concrete work and repairing cracks in concrete for close to 40 years.

After fixing hundreds of these cracks I've learned some tips and tricks that make repairing these cracks quite easy that I want to share with you. 

What are Some of the Benefits of Fixing the Crack myself?:

Some reasons why you may want to think about repairing your own foundation crack are:

  •  Save yourself a significant amount of money
  •  Don't have to worry about hiring a "bad" contractor
  •  Get the crack repaired faster by not waiting for a contractor
  •  Save a lot time - getting multiple estimates could take weeks
  •  I have an easy to follow diy tutorial that shows the step by step process
  • You can watch the video of me actually fixing a basement wall crack and showing you my tips & trick to easily perform this task.

What's my "secret weapon" repair material?

It's called RadonSeal DIY Foundation Crack Repair, it's a diy crack injection repair product that's easy to use and will completely seal your crack, stopping it from leaking.

I wouldn't use it for my customers if I didn't think it was the best crack repair product out there. (Trust me, I've tried a lot of them)

Radonseal's Crack repair has never let me down, It's always sealed any leaking crack I've injected with it. 


My "SECRET" is that it's so easy to set-up and inject the crack with I really don't want diy's to know. If all you guys know how easy it is to use, you'll stop hiring me.

"I'm just kidding" , there'll always be someone who needs a professional to do it, but if you're even a little bit handy around the house I honestly feel like you can complete this project yourself.

Why is this crack repair kit diy easy?

What makes this foundation repair kit so easy to use?

  •  You can completely seal the crack from inside your basement walls
  •  No need to excavate and repair from the outside
  •  No drilling required - just inject the crack as is
  •  Fills hairline cracks - The very low viscosity of this material gets into the narrowest of cracks
  • You don't need any special tools - All you need is a caulking gun 

Why is this kit better than others out there?

RadonSeal foundation crack repair kits use a two-component injection polymer.

It's a proprietary 2-part polyurethane that expands 20 times its volume to fill the entire depth of the crack.

This 2-part hydrophobic foam repels water and will not break down over time.

Cheaper repair kits use a single-component hydrophilic foam that absorbs water but eventually fails after repeated wetting and drying.


One kit like this will repair 8 - 10 lineal feet of 1/16" - 1/8" wide crack.

Make sure you order enough to completely seal your crack(s).
