Damp wall and floor lifting - vents causing this?

How where the oak floorings laid in the 1st place, ie, were they nailed, glued to each other and the floor, or just glued to each other.

The point is it either needs to be fully floating or fully fixed, the fact that you say he has removed a section of flooring makes me wonder.

If the floor isn't fixed, the weight of furniture can cause solid wood to lift during periods of high humidity as it can prevent expansion. It becomes easier for it to lift rather than to push out towards the walls.

There are wooden floorboards under the oak flooring....

The floor was nailed (using a special instrument)...he used glue too (in the grooves??)

To clarify, he removed the last section of the flooring - next to the wall...

This is the OPs second thread on the subject. You contributed a lot on the other one.

The problem remains the same IMO. Your outside ground level is too high potentially bridging the DPC. Water in one form or another s getting in through the air vents, water is probably splashing up over the DPC during heavy rain.

In short you have humidity and ventilation problems in that room which need addressing or the floor will never be right.

Hi All,

I have 2 separate issues

Issue1: My solid oak floor that was laid 2 months ago started to lift. The guy who laid the flooring came back and removed the beading to check. There was still space to move (even though very little in some cases). He then removed a few rows and said will come back later to check if it has settled down.

I have a through lounge. There is an external vent exactly below the garden door. If you draw a line from the vent to the other end of the lounge/diner, thats where the floor lifted. On the other side of this "line", there is another external vent.

Could the rains + vent have caused this?



How do I resolve this???

Insufficient expansion gap has caused the floor to buckle. Fitter needs to fit the floor properly.

Yes, I thought it was a double take:D

I totally agree with you, treat the disease not the symptoms. If I recall now the floor was nailed.
Not well enough evidently.;)
