Normally people will raised their platform using laminated wood. But my friend is supplying tiles, I plan to raise my platform using tiles. Is that alright?

The platform size that I plan to raise is somewhere 100sqf with 6 inch height. My current family hall flooring is laminated flooring / parquet (I not sure). Do I need to hack the flooring before lay the tiles? And what I should use to raise the 6 inch height? Cements? or ..?
