Concrete failure under epoxy coating

[Love2Shine]

I had my garage floor coated by a local floor coating business about 2 years ago. They did an excellent job. Full project with diamond grinding, filling gaps and repairing cracks.

Unfortunately, with the crazy winter we had in central PA, it seems some moisture has penetrated into one of the cracks on my apron and is blowing apart the concrete from below.

The floor is holding up well in general though:

Tomorrow morning the flooring company is coming by to check it out and tell me what can be done.

How old is your concrete?

How old is your concrete?

It is about 12 years old.

Call them back. Repairs are possible. They'll need to grind the area to solid concrete and re-coat easily enough. They could just touch up that area.

When I do my floors, I cut a key joint where the seal sits. I then treat the floor as two separate areas ( inside the garage, outside the garage) I hate coating outside the door, for the inevitable failure ( At least here in Canada) When it fails, it can be re-coated easy enough at minimal cost (Whether you're paying, or they're paying) I suggest to my customers to not coat outside the door, but rather just to paint it to match the driveway.

Stronghold Floors came out Friday morning to take a look at the damage. As I suspected there is additional concrete repairs that need to be done. They said they will take care of it with no charge to me.

He also gave me 2 tubes of Sikaflex urethane caulk to apply to the joint between the apron and the driveway after the repairs are done. Hopefully this is to bridge the existing gap to keep water intrusion to a minimum.

We are scheduling the repair sometime in April.

Sounds like they are a reputable company, they are fixing it for you at no charge.

That is good of them to come out for no charge... let us know how they go about fixing it.

I cant seem to see the pictures, but I would recommend cutting out the area that is failing, priming, filling with a resin/silica mix, grinding flat, and then re-applying the entire coating system over the patch. It will most likely look like a patch though, but will blend back over time/traffic. Make sure all the joints exposed to moisture are filled.

Not sure what happened to the pictures. However...

The crew came out and over a process of 3 days they repaired both aprons. They ground down to solid concrete and then built the floor back up with something that set up in about 5 minutes. They said it is some pretty nasty stuff to work with.

They ground that stuff smooth and they laid down the new coating and then the wear coat. I am very pleased and it is a pretty good match to what is currently on the floor.

That area is usually the weak spot in any garage. It received the last of the pour and was likely the last thing troweled. Many masons "wet the trowels" to make it workable as it begins to get hard. This makes for surface weakness. Repair looks great.

Seems like a very decent company to do business with. Looks great.

What a great testament to Stronghold Floors. We've heard stories like this about them. There are many installers out there that would be quick to say it's your problem and want to charge you for the repair. They did a good job.

I have had a couple contractors run the epoxy to the expansion joint and it aways fails. I like that you cut a joint great idea. We have been telling the contractor to do the same but most don't listen.
