Am I right in thinking that this is power floated concrete? Been down about 18 months, was carpeted but putting down engineered. After reading Matt's post from a while ago, did moisture readings with both hygrohood and probe- hood reading 62% after a few hours, probe 92% so guessing this confirms it as power floated?

Yes looks like a power floated floor They stay wet forever Needs the top grinded or shot blasted to give the dpm a key or even scratch the living hell out of it with a copper disc at a minimum
Cheers. Does it need keying even if I'm just floating the floor on an underlay? No adhesive to lift the dpm. Or best keying anyway? Sent from my iPhone using Tapatalk
If your ur floating on underlay why don't you just put down a isolator sheet? Saves a lot of mess Sent from my iPhone using Tapatalk
I'll get some prices and see what works out cheaper, thanks for the advice Sent from my iPhone using Tapatalk
If it's a domestic property, it could be agilia. Is there any waxy residue anywhere ? Sent from my SM-G930F using Tapatalk
If the integral DPM is totally impervious then 75% should be fine. Ask the underlay manufacturer what they recommend.
