Carpet, tile, or maybe even wood: uneven concrete basement floor

In Denver's metro area where we are, there are houses everywhere, with basements, all built over expansive subsoils, in which the basement floors are quite uneven. We are in a community of newer homes, a couple thousand of them, all production-built, and basement slabs are anything but flat.

Recognizing the floors would heave, the builder placed construction joints on 6 to 8 foot centers, so the floors are are scored like a grid. The slabs break at the joints, and rock and roll as the subsoil expands and contracts.

A large number of these homes have finished basements, with the rooms almost always carpeted.

How is this done? Do the carpeting contractors use fillers for those deep V joints at the control joints? Do they use floor leveling compounds? Do they use multiple layers of underlayment?

Welcome to the forums. Not sure on the slab breaks. My daughter lives in Highlands Ranch, and that was my first experience with floating walls. Their floor is a continuous monolithic slab with rebar running through it so even if the soil expands, the floor will move as a unit, or so it would seem.

How much heave in the sections are you experiencing?
