A lift requires a footing under it, so if the floor already exists, you're screwed.
It withstands compression very well.. especially when reinforced with rebar or put under tension in press-stressed members.
Floors are for walking on, supporting other structures, pretty basic stuff. Dirt is and was likely the first flooring material, probably stone(s) came next. Floor coverings do just that, they cover & modify the usefulness of a servicable basic floor. the Hides of the animals we killed & ate & wood, stones & even baked clay tiles that we found under the fire pit all came next. Today we use rugs, wood, Carpets, Ceramic, Stones & poured floors such as concrete as floors & floor covering.
Concrete backer board is usually used as an under layment for ceramic tile. It can be used on walls, floors or countertops. It has a solid core and is faced on both sides with fiberglass.

reinforced concrete is better than unreinforced concrete for one major reason. concrete is an extremely strong material when it is put under pressure. however, when tension forces are introduced it will tend to fail without reinforcement. short answer: unreinforced concrete will handle a lot of weight, but it is very brittle. source: carpenter
You should always use an underlayment for hardwood floors. Use either Red Rosin paper or 15lb Fortifiber hardwood underlayment. Fortifiber is recommended, heavy duty and better quality vapor barrier.
Mud jacking is a concrete or foundation repair method that is typically used in regions where the ground tends to settle, causing foundation issues. A foundation repair expert can tell you whether mud jacking is needed, a technique that basically fills in the settled area with pumped in dirt and cement mix. Mud jacking is what you need if you have sinking or sunken concrete driveways, patios, walks, steps, or garage floors. Concrete mud jacking fill the voids under the sunken concrete areas with a slurry that’s made of clean soil and cement by forcing this grout into the voids and this lifts or raises the sunken concrete back to the correct level and the grout fills the voids and stabilizes the soil so you won’t have to worry about the concrete sinking again.
You can but it will not grow. it will if theres water under the concrete
