Should you fill cinder blocks with concrete?
The reason filling is not recommended in most cases is that as the joining solution (mortar or concrete) you use to join cinder block solidifies, whatever you add within will diffuse the moisture inwards. Not only with that, even if you're adding soil, there will be moisture within. Concrete, of course, will be wet.

Basement plumbing for floor drains and piping must be roughed in before the pour. Like a slab floor, the basement floor will be lined with a six-inch aggregate bed followed by a six-mil polyethylene vapor barrier.

Wire mesh comes next for structural strength, and flex tubing is set in place if using in-floor radiant heating. Finally, the concrete is poured on top and leveled with a screed.
