How I fix cracks in concrete floors and walls

Hi Everyone!

It's no secret, we all know concrete cracks. In most cases it's just normal shrinkage cracking.

In other cases it could be the sub-grade settled, or the ground froze and heaved causing more stress on the concrete than it could handle with the end result being a big crack.

If you have a crack in your concrete floor or foundation wall, I'm going to show you how to fix it.



We recently completed a project where we had to repair 75 cracks in a foundation wall.

This was a large warehouse and a lot of the cracks were leaking. The owner wanted the building to be water tight so the cracks had to be repaired.

We repaired all the cracks using a DIY crack repair kit by RadonSeal.

I show you how we did it here: How I fix cracks in foundation walls


We also repair a lot of cracks in concrete floors, just like the one you see in the picture below.



When we do an epoxy coating on a garage floor we always repair the cracks first.

I made a video to show you how I repair these cracks, it's easier than you think.

The crack repair kit we use to fix these cracks is also from RadonSeal. If you follow my instructions step by step, I'm confident you can do it also.

If you need to hire someone to fix cracks like the ones above, it can get expensive. That's why I'm showing you how to do it yourself.

Let me know if you think you can fix these kinds of cracks after reading my information and watching the videos.

ALSO: Let me know if there is a topic about concrete you would like me to write about.

Have a good day,

Mike Day
