Laminate question

kayl

I wonder whether anyone can help me.
When we moved in just over 6 years ago, we put down laminate flooring in the kitchen. It was expensive stuff as it is a large area, and it was supposed to be 90% waterproof, so it was suitable for a kitchen. After about 6 months, it began springing up in one place, and after investigaion, we discovered that our plunber hadn't put our dishwasher in properly, and so it was leaking underneath. We claimed under our accidental damage insurance cover, and replaced the affected part of the laminate.(although we did not replace the underlay)
Gradually however, the problem has come back. The boards have not come up by a huge amount, but where the edges are slightly raised, they trap dirt, which I can only remove with a knife edge, and if anything is dropped on the raised areas the laminate chips. It really looks fairly unslightly, regardless of how often I clean it.
There is no way I would replace it with laminate (aside from the cost question), and I wanted to put down heavy duty vinyl. I wondered whether I would be able to put the vinyl on top of the lamibate, or whther the raised areas would prevent this. My husband has no longer with me, cost is a major issue, and I could not afford to pay a joiner to remove the laminate

if the planks are lifting, then you must remove them, before you install anything else.
i would go for floor tiles not vinyl.
