**EXPERT Advice Needed** - VERY Moist Slab With LOTS of Vapor! What to do?

[john macdonald]

Contact Ben Warner @ ben@hi-techinteriors.com. Ben had a vapor transmission problem very similar to yours. He had installed an epoxy floor for a hospital, it failed 1 1/2 years later. He returned saw blisters, opened these and found water. He had installed this after confirming that the VT was 3lbs. The reading was now 8lbs and he could not understand this.

After calling all his contacts he was told to call me. I am not a flooring expert but a concrete hydration specialist. I asked him why he was surprised at the VT variation as OPC concrete is simply a hard sponge and any VT reading today can change tomorrow (as his did).

I am not going to tell you what I told Ben but if you call him tell him John Macdonald from Calgary told you to call him about water in your concrete and how to rectify this. After, if you believe Ben then call and I will explain to you how concrete without sealers, membranes or any other deflection technology can be it's own vapor barrier by simply managing the cement and water efficiently at the time of placement or reactvating the cement content 100 years later.

Best regards.
