Toungue Now you see why I don't want Bob on this site!
I know a couple of us are on the LinkedIn Group discussion about RH probes and Bob and I are having a cyber fist fight....

In a nutshell he's saying RH is an inaccurate and complicated method of determining free moisture in concrete, and in fact our RH probes are easily fooled by temperature, pore structure and natural concrete constituents! Sad

I have asked him to put his money where his mouth is and guarantee a slab using CaCl and EI meters, and I'll provide the slab.

I think he just wants to sound like he knows something and comes up with these cotton balls in jars and wood chip sorptive scenarios for museum curators that don't amount to a hill of beans in the concrete world.

I told him we don't put floors over jars of cotton balls.... Big Grin
