Mina, could we have a few more details? We can't tell you how to fix it unless we know is causing it to buckle.
1) Is the product Formica or another brand of laminate flooring?
2) Is it actual flooring or countertop laminate applied to a floor?
3) Who installed it?
4) Where was it installed and over what material? Old flooring? an old sub floor? what? Is this a bathroom, basement, kitchen, hall, where?
5) Did you have some water damage?
