Basement rads on a rat slab ...

Folks. Image is one of a few refurb rads to be connected this week for basement heat. I'd like to try to get a moisture break under the feet to delay the onset of corrosion. What should I be considering ... pressure treated, PVC, etc? Thanks

    That’s a cool old wall.  Can you imagine wresting those large stones into place by hand?
     I use something like this for direct floor:  4-Pack 7/8 In Black Rubber Chair pads

    I built boxes out of PT 2x10 to get mine off the floor.   I also put them in on interior walls.

    Corian or granite pucks made from kitchen counter top scrap. Fake plastic wood used in outdoor deck construction. No real wood, PT or not. All basements flood sooner or later. All basements are too humid sooner or later.

    Thanks all. We found some unused synthetic panel and cut a few "coasters" from that.

    @PC7060
    IMO: I would not recommend this elevated Installation technique unless it is really necessary..
    Very little convection will remain..
    By Installing the radiators that high the BTU output is reduced drastically and additional rads may be required..
    Then again...It's just a shop and you have Plenty Outlets for the "Electrifcation"... :#

    We went with PVC pads. Copper risers to O2 barrier PEX running in the basement ceiling back to the boiler.

    @Derheatmeister - no disrespect but I don’t see how raising a radiator 15” in a 8’ tall room has any impact on performance. If that was the case how would any wall or ceiling mounted radiator be feasible or effective?

    Not disrespect taken...Proven fact is that a radiator is not as effective when you raise them off the floor...They will still work but you will loose some of the convectional properties..
    Radiant properties will remain the same not matter how high you installed it off the floor ;)
