WOODEN FLOORING RISING Help, advice, information, answers and tips on all types of flooring from laminate and carpet to timber and vinyl

[suzanne hughes]

OUR DOWNSTAIRS FLOOR IS CONCETE, THEN A LAYER OF PLY WOOD AND FINALLY WOODEN BLOCK FLOORING. THIS IS IN MY TWO DOWNSTAIRS ROOMS AND HALLWAY. I HAVE NOTICED IN THE TWO ROOMS THAT IN CERTAIN AREAS THE FLOOR IS RISING. THE HOUSE DOES SUFFER WITH CONDENSATION. COULD THIS BE THE REASON THAT THE FLOOR IS RAISING? COULD THE PLY BE ABSORBING THE MOISTURE AND THEN EXPANDING? THE PLY WAS SCREWED DOWN INTO THE CONCETE. IF WE PULLED UP THE FLOORING WE WOULN'T BE ABLE TO RELAY IT AGAIN. ANY ADVICE?

suzanne hughes,
When the floor was laid an expansion gap of about 5mm should have been left on all side of the plywood. You have little choice but to relay the floor.

Was there a Dpm placed under the ply and on top of the ply? if not then get in contact with your floor fitter and ask why!
