It would always be best to remove the existing, but sometimes it is cost prohibitive. To pour a slab over an existing slab, especially if it is uneven or fractured, will cause weak points in the new slab for various reasons.

Commercial solutions are available also to aid in the adhesion of new concrete over old. These products are available at most home stores.
