New carpet tile on basement concrete floor

Have removed the 1960s indoor/outdoor carpet that was glued to the basement floor. Concrete is cleaning up reasonably. Next step is to put down the new,large carpet tiles.

First, do I need an under layment for moisture like what was needed for engineered hardwood? Or can I glue direct to the concrete? No moisture problems ever.

Varying views from carpet suppliers

Any comments appreciated, have installed lots of tile, never carpet tile

If you had previous carpet down there then you should be good to just move forward with your carpet tiles. Understand that carpet tiles use a pressure sensitive adhesive to adhere. You trowel it on, let it dry, it is tacky at that point and you install your squares. Don't use regular carpet adhesive.

With carpet, if you get a little moisture it can evaporate through the carpet. With a moisture barrier, moisture can sit underneath it and grow mold.
