All patios need to be built on a level surface no matter what materials you end up using. Cracks in concrete, uneven surfaces and pooling water on the patio can all be attributed to an ill prepared sub-base.

There are differences on how your patio will be built depending on the hardscape material you choose. Typically, it  takes about one week to install a basic patio, but longer for larger, more elaborate designs along with nearby planting installations.
