I am laying a laminate floor onto a downstairs chipboard floor. It seems as though the sub floor is beams and boards placed on some sort of insulation, which I guess then sits on dpm/concrete.
Along one edge the level drops slightly - it was noticable with carpet so will be a nightmare with laminate. So I need to level it up before I start - the discrepancy goes from nothing to about 1.5cm in the space of about 4ft up to the wall. I think previous occupants have had heavy loads in this area that maybe has squashed the insulation material - or that the builders bodged the level of the concrete - there is no sign of huge gaps appearing under the skirting so it doesn't look like it's dropping - and it hasn't changed in the 18 months we have lived there.
I got the thicker underlay (fibreboard stuff) to iron out the usual slight bumps and lump but this won't help here I think.
I was thinking of packing using old carpet underlay / foam underlay as appropriate for the depth of problem, and then putting the laminate underlay on top of that but this could be tricky to get right?
The house is under 10 years old so is built out of paper and glue it seems!! The builders haven't fixed any of the chipboard down so I'm going to be screwing that down in the corners of all the boards first.
Anyone got any other ideas? Can you use self levelling compound on top of chipboard - and can you use it in a specific area rather than the whole floor?
Many Thanks.
