So to cut a long story short I have had some 'bouncy' pieces of laminate since fitting earlier this year after moving into a new build, it turns out the floor was all tight against the wall and appears to have had no expansion. Its laminate from carpet right and their timbersafe underlay with the silver moisture barrier (new build concrete sub floor) the whole down stairs is the laminate, hall, lounge and kitchen/diner.
The fitters have been round a few times trimming pieces to try and level it and finally came back yesterday to take the flooring up and re-do (its been down since January) and when lifting the timbersafe underlay which is a kind of rubberish material witht he silver bottom felt damp/sweatty and appears to have lost the silver colour on the sweaty parts and turns out it was this way throughout the whole of down stairs where the boards sat. Under the kicthen units where there was underlay but no boards was still like new. They said there must have been damp in the floor (no damp probe to check) although the floor is bone dry and even the saw dust on the floor left from original fitting was still dry and 'dusty' the building site manager also popped round and had a look to confirm the sub floor is ok since theres no moisture damange to MDF skirtings etc.
I have attached pics of the old stuff, they also re fitted with new underlay which is the 3mm foam with the moisture barrier which is attacked also. This was the original stuff https://www.carpetright.co.uk/underlay/timber-safe-silver which was rolled out and not taped or anything. It looks to me like between the laminate and the moisture barrier of the underlay was 'sweating' somehow which has made the underlay look 10 years old.
Is that underlay fine on concrete? The house was build for a few months before we moved in so the sub floor should have been OK to lay strait on to at the time. The fitters said they have never seen that underlay go like that. They didnt use any moisture metres or anything, said they are not really needed.
