Uneven floor

Hi, I'm trying to finish my basement and the floor is giving trouble in one particular room (the laundry).At first, there was two water heater in the room and a workshop and there was no plan on finishing this room until I moved everything in the garage. The floor is really (really) uneven. There a slope making it in the center of the room where is the basement drain. From the center of it, there's about a 5 inch difference between the exterior wall (which is about 5 feet far). So the slope is quite "intense". From the other side the slope is about 2 inch on 7 feet distance. I'm just trying to figure the easiest way to finish it off. Any suggestion? I'm not planning to add any concrete for this project, maybe a subfloor (but how?).
Thanks.

Since it's the laundry and there is a floor drain, you need some slope. I'd say you should just clean the floor up and epoxy it.

 

And you should be thankful that it's there!

So depending on what your wanting to do to the floor your not going to really want to change that. So what type of floor are you thinking about? Many are just concerned about overall flatness and the slope would not be an issue!

 

, exactly. If there's a small slope, no problem about it. But has I said, 5 inch slope on a near 4 feet distance, it's too intense. I was thinking at first to put tiles and "reduce" the slope with cement but when I measure de 5 inch difference, I step back. Somebody told me that contractor would just put a subfloor over it (leave the floor drain as it is just in case) and put whatever I want on it (vynil...).

 

Could make a subfloor over the top, guess you have to decide if the effort is needed?

 

It's just a bad idea. To level a floor with a 5" slope you would add tapered sleepers over the floor, then a subfloor on top of that and your finish floor would be a minimum of 6" higher than your low point which would create a step up at the doorway or wherever that new level subfloor would end. If you want to envision it, borrow a laser level to see the level line on your walls, and measure up from the floor to the laser line at various places. Plus if you bury the floor drain you would get sewer gas out the floor drain trap when it dried out (you need to dump water in them every so often) or in the event you had a sewer backup you would need to tear all that out to clean up the sewage underneath.


As I said my suggestion would be to forget it and epoxy the cement so it looks better and is easy to clean.
