Leveling part of concrete slab

[R3DS!X]

Howdy,
We are trying to partly level out our slab to build a subfloor. Most of it is level enough but a section that is about 20ft x 5ft starts to slope and fairly aggressively in some parts. I see self leveling concrete says it's only for up to 1-1/2". For anything beyond that depth should I fill with gravel? Use pressure treated wood? Regular cement?

do multiple pours of the self leveling stuff.

has the reason the slab isn't level been fixed?

I don't think it was ever level throughout. The house is on a hill and the back half of the house was level and the garage has a slope and we are building out into the garage a bit.

Good luck. That sounds like an expensive undertaking.

My neighbor got a "good deal" on a job to level his home- it was $30K. I have looked at doing the same and it's gone up!!!!

Why not float a subfloor?

Maybe I don't understand construction well

Take the self-leveler to a point and then do sleepers after that. I have no idea what you're trying to level and what you expect to put on top of it. The short answer: cutting corners or not really knowing what you're doing doesn't mean that it won't look good--for a while. Usually the trade-off comes in longevity. Craftsmanship and knowledge are two different things.

So the base is concrete, which is cold and moist, so you gotta make level subfloor for laminate flooring. pressure treated wood goes down on top of concrete(sleepers) and xps foam is going in-between those. on top of that tongue and grove 5/8" plywood on top of those. That all works fine and good except for the one end of the floor where it aint level.

so i need to level that shizz

Someone sacrifice a goat for me I'm gonna give it a go tonight.

Interesting. I guess I was thinking of a floating subfloor as being similar to a second story floor.

Seems a bit different

Thanks for the informative

I could be wrong im no geneius but usually when i hear floating floor its not a sub floor but a top layer

add in vapor barrier too. How much are you trying to level? Can't you scribe the sleepers to fit level or shim them?

could for the sleeprs, but then im, stuck with the xps foam not being flush, which adds rigidity to the subfloor. the XPS foam serves as a vapor barrier.

He might mean between the floor and the wood. And just because something can withstand water doesn't mean you don't want to keep it from getting wet, insulation being one of them. Performance is compromised, and now the water is just that much closer to stuff that can't get wet.
