Click laminate boards on concreteclic
A slow leak from the washing machine resulted in my laminate boards buckling and swelling. My builder advised concreting the base, previously false floor of hardboard. Concrete was done and the laminate laid 3 days later. Laminate has been slowly buckling such that I catch my shoe and the mop where it is raised. Some of the laminate boards were recycled and some where new but they are all buckling. The kitchen runs into a glass roof conservatory and it is the conservatory end which has been replaced, What should I do?
Your concrete has not dried completely. Depending on the thickness it can take several weeks.
Remove the laminate and let concrete dry. Damp test it occasionally. Once it's dry enough to lay laminate, make sure put DPM (damp proof membrane).

as vp property have said the concrete is no where near dry yet, although a couple of weeks is very short of the drying time it takes as a rule of thumb roughly 1mm a day to dry so an average concrete base will take in the region of 18 months to dry naturally. After a minimum of 4 weeks you can fast track this with a paintable surface DPM but this must be completed by your flooring professional and no other tradesman it is specialised work.
