Hi Tiffany! You should check out Basement Systems ThermalDry flooring! They have plenty of options based on what you need. Feel free to reach out with any questions you may have.

If you're not finding liquid water, the likely sources are: 1) vapour diffusion through the concrete due to the inevitable pressure differential between the soil and the basement interior; 2) interior humidity hitting the cold basement floor. (See here for an impartial expert summary of moisture management in basements.)

Instead of wasting more money trying to transform the concrete into a water/vapour barrier, use a subfloor system that equalizes pressure and protects the finished floor surface.

I would recommend using a subfloor product such as dricore which creates a small channel under the floor for small amounts of water.

To the worthy's "inevitable" point, unless the slab is done REALLY well, you're going to end up with water under the concrete somewhere, and concrete wicks. I've yet to see a "normally produced" home that has the poly under the slab done completely right (i.e. all seams taped, penetrations from pipes sealed, use of non-sharp gravel to avoid small punctures). Once that small amount of moisture is in your slab, You can deal with that small amount a few ways. 1) use a subfloor system that permits the moisture through but attempts to provide a drying or draining mechanism and keeps it away from the finished floor for it. 2) Cover the concrete in something with a very low vapor permeability that won't rot or degrade and make an insulating vapor barrier (i.e. XPS foam board) under your flooring. Your "tote" is a perfect example of this. All the water under that container was kept there until you lifted it. Imagine one large unbroken tote from wall to wall. Unless you have running water, this will keep the ambient moisture in the slab right where it is if done well. 3) Use a flooring product that is semi permeable, like stone or tile, and simply condition / dehumidify the space and be mindful of what is left sitting on the floor. If you try to use a masonry flooring that blocks the water, it may loose its bond over time from vapor pressure.
