Garage Floor

Rambone

Does anyone know if you can grind down a concrete floor to make it level and smooth. I have a house that the builder poured his own floor and did this to SAVE $ . Now the owner has water running in the corners and the garage doors won't sit flat on the floor because it's to unlevel.

How far is it off? - Grinding ain't cheap, and rather messy. What about a self-leveling top coat?

It has a 18' door and is about 2" differance from one sid e to the other.
I was thinking of a top caot but how will that hold up in the long run.
Oh ya did I mention this garage has radiant floor heat.

No, you didn't mention that, I believe that will make a difference...:-)

A couple of years ago, did a job at a bank that had ceramic tiles on the entrance to the building. People were doing backflips whenever we got a little snow. We removed the tiles and cleaned it down to bare concrete. After a bit of research we found a product that could be poured a 1/2" thick (a grout) that, as long as you used the recommended bonding agent was guaranteed. We could only go 1/2" thick (thickness of the tile because of the doors).

I believe it's designed as a topcoat for driveways?? You'd probably have to do a slight coat on the whole pad (I would think feathering it would probably crack near the edges). That was 2 1/2 years ago and still holding up great. Check around at some wholesalers I'm sure they probably have a product suitable for the situation.. You might have to tweak the garage door too (no biggy) ..

2 inches? WOW......I think someone would have to work at that! You won't enjoy grinding down 2 inches of concrete...overlay would be the feasable way...or saw it out and re-pour it higher maybe...floating it to the sills....

This may sound crazy but I was going to suggest a garage mat that should rase it enough to seal the garage door. but the cost of these mats are around $2,000.

About 4 years ago we did a job that at a school. In one corner of the music room there used to be a small 3' deep 4 step down for students with instruments to sit on and play. Well a few years earlier the school wanted to fill this in and just have a flat slab, the room was all concrete. The gc who did the work must have had a bad laser or something because it was out by 4 inches in the worst spot. We came in and did some reaserch and found a product that was a mix between a thinset and a grout. It only came in 80lb bags and we had to mix it in buckets but we feathered it out over about 200 sqft from 4" to nothing. It had almost no lip at the edge and self leveled great. I can't remember the name of the product and can't find it in the records but it didn't take much work to find it. It was covered with commercial grade carpet after a month or so and I've heard nothing from them. Worked slicker than s--t.

Standard concrete garage floor construction requires that the garage slab of a 20’ deep garage, be sloped 4” towards the garage door. Grinding the concrete floor is not a satisfactory solution. There are many good top coating materials on the market and it should be noted that most good top coating systems involve special preparation of the existing concrete floor.
