I had a laminate wooden floor put down onto a kitchen sub floor that had had a narrow trench filled with 3 week old concrete containing new hot water pipes running through the middle of it.
After a month, the new laminate started to buckle and on inspection water was forcing its way up between the planks only along the line of the concrete. I assumed it was a leak from a bad weld of one of the pipes into the concrete under the laminate/underlay, but when we pulled up the floor the concrete is bone dry. Though the underlay was soaking, and the laminate ruined all the water quickly evaporated and there is nothing suggesting a leak.
I suspect that the concrete was and is still giving off moisture, though feels dry to the touch.
When the floor was laid, the concrete was 3 weeks old and was being heated every day by the hot water pipes running through it.
I now have a ruined floor in a brand new kitchen, and no clear advice on how it happened or what should have been done to prevent it.
NB There was no prior problem with damp, it is a ground floor room.
Can anyone advise?
