Hello,We had an engineered oak floor installed in our home two weeks ago. The floor was glued down over the cement slab. What we have noticed is (1) there are a lot of gaps between the slats (some as big as 1.5 mm); and (2) there is one area where the glue did not stick and now the wood is lifting. This area is in the middle of the entry hallway and we hear a hollow sound when walking on this place (it can be pushed down by hand). My question is are these normal or do we need to contact the installer/dealer to have something done or complain? Thanks in advance for your advice.Jim
I'd start by getting the installer back in to see your problem. It may be an easy fix.
I think the floor was improperly installed,if they didn't leave a 1/4 to a 1/2 inch expansion joint around the edges your floor is buckling.
