How to Fix garage swimming pool

[central1ny]

I had a garage built in the fall of 2011 and the concrete guy that did the slab didn't do the best job at creating a flat slab. On one side of the garage, there is a concave area that collects substantial water. He was supposed to create a 1" slope down toward the doors, which didn’t happen. It became painfully apparent that the slab was much worst than I thought the first time we parked the trailblazer over that area and the snow melted. It looked like a shallow swimming pool.

In any case, what’s done is done. The guy was a hack and we had a few heated discussions when he was on the job. I should have fired him but I made a mistake. I don't ever want to see the guy again and it is not worth my time or money to pursue the matter in court.

So I am looking for a solution as to how I can fix a relatively large area in the center of one bay that collects a lot of water. The area is approx 10' x 10' and maybe 1/2" deep. I plan on eventually using an epoxy coating over the entire floor so the repair does not have to look pretty as long as it is smooth, can be feathered into the rest of the floor, and is durable.

My first thought was to go with some sort of two-part epoxy and fill in the area. I would try to get it fairly flat when installing it and then use a grinder to feather the edges. Is this a good idea? Any other ideas?

It can be done.
You have to do this the same way a tile installer would fill a void in a floor ready for tiling. You need to identify the area that needs to be filled by putting a long straight edge across it in several directions. As you fill you need to be able to keep checking this straight edge to make sure you are getting it done and not over doing it.

Once the area has been filled, you need grind it with a walk-behind unit to gain a smooth transition or you will have an eyesore or worse yet a tripping hazard.

I would start with the straight edge to see how big this really is, it might be larger than you think.

Pics would be good. There are some excellent installers on this forum that will give you additional tips and/or solutions.

I would look at self-leveling toppers. My personal favorites are Mapei M20+, or UltraTop.

How does the self-leveling topper compare to an epoxy conctrete patch for durability?

Subscribed. I am looking for the same thing except my garage floor is sloped to the drain. Can I use a self leveling product and still fill the low points so the water flows to the drain?
