Concrete question?

[armascott]

I know there's a few threads on here about concrete, but I could find an answer I was looking for. Therefore I'm starting a new one.

My my garage floor has too much slope to it. It's a triple with 2 drains, one on the single side and one on the double side. I'm planning on putting polyaspartic on my floor this spring but I would like to level the floor out a bit first. What should I use? I'm guessing it needs to go up about 1" around the drains and taper out to nothing closer to the walls.

I would recommend Sika self leveling underlayment. Sika products are the best you can get with out getting into the ridiculously expensive products. It takes a little bit of work to use it and try to still keep some slope but can be done with the proper self leveling/gauge rake and some time and patience

So I was a bit off on how much to needs to go up. 3 1/2” drop over a 8’ span.

Hate to say it, but holy crap is that floor a pile of chit. It won't be fun trying to top that to get rid of the insane slope, get it to actually stick, and raise the drains. You're going to need to top the entire thing IMO, because it is so unlevel, if you go down to a reasonable slope of 1% suitable for a garage, you're going to get a lot of puddling. In 8' you should have 1" of slope. Topping 2.5" is a lot.

Do you get any puddles now?


I would trade that extreme slope for my mild slope puddle fest anyday!

 

[armascott]

LOL no puddles now, my issue is working on anything in there. For example dirt bikes on stands any more than 1' away from the wall are pretty tippy on stands. I have to cover my drains with rags, put bikes in the middle of the garage to do any wrenching. I've also had to shim up all the legs on tool boxes, shelving units etc to level them up.

If it were me I would do that in two pours, regular for the thicker part down it about 1.5 inches then the expensive quick setting topping concrete for the perimeter edges. Then finish the whole thing off with a garage flooring material, I think Costco carries tiles.

Wow that is quite the finishing job. I do concrete for a living in the states and I have no idea y someone would put that much slope to a drain. If it was me personally I would tear it out. Raise the drain and repour with 4" of concrete. I am not sure on what equipment u have available to u but if u tore it out yourself and have a concrete guy pour it and finish it for u. You would save a lot of cash sense there is a lot of labor in tearing it out. It will definitely be a better finished product then top coating.

I’d would trade the shims for puddles personally! I have a decent slope but still have a couple spots that dry slow or collect a minor puddle. Sucks extra when my outside dogs that sleep in the garage at night, leave the piss puddle. I think it will be really tough to get it to drain perfect with the minimal grade, especially if it’s a topping coat.
