Finishing a sloping concrete slab floor

Hi there - just looking for some advice.

We currently have an at-grade concrete slab floor on the ground level of our home - no basement. The slab is terribly uneven - one corner is nearly 3" higher than the lowest point of the slab (drain), and the remainder of the slab is lower than this corner in varying amounts. We are thinking about using 2x4's as sleeper boards and tapering them on each end along the slope of the floor. My issue is - should we use pressure treated wood, as it will be against concrete? Is there another option of material or can untreated wood be used if a plastic sheeting is underneath? Should a hole be cut in the plastic sheeting above the drain hole?

Any insight would be appreciated!

You can absolutely do that with the 2x4 but you must use a sil gasket so the would isn't just against the concrete for moisture puposes and make sure it's the cienna brown pt not the green too much kerosete good luck on your project you can also rent a big cement grinder from home depot as well to level your floor too it's a bit messy but it works
