Hi I have concrete floors in my house and at some point the kitchen has been knocked into a kitchen diner. To that ammends there is a ridge/lump where some of the previous adjoining wall has been (possibly a pantry). It is approximately 4 foot square and is raised about 1.5 inches. There are no water, gas or electrics any where near it and I want to lay laminate flooring over it. The remaining floor slopes away gently and will not be a problem but obviously if I put laminate over the ridge/lump it will look rediculous and the laminate with bend and the joines will show. Can anyone andvise me on the easiest and most effective way to remove this ridge/lump so I can then lay the floor. Any advice on this subject will be greatly appreciated.
