Why would a laminate floor dip at the edge near an supporting wall when heavy item placed on it.
We are looking to buy a house but noticed where the laminate sits at wall edge next to a set of French doors the floor laminate splits down showing a 5/6 Mum gap around 1cm long. The grove seems to slip out on the lock and does this at both sides where the cabinet stands.
Any ideas why this might be. Current owners didn’t lay the floor and are not sure if the floor is cement or suspended plus they do not know what underlay was used.
Any advice about what might be the cause and if it’s a problem to start clear or or something that won’t be costly to correct

Often people install laminate floors on a foam based underlayment. It's possible the heavy object is compressing it sufficiently to cause the gaps.
