I would like to switch to a gas cooktop. The difficulty is that the island where the cooktop is located does not currently have a gas line run to it. The nearest line is ~20 feet away and I have a concrete slab foundation. Is there a practical means of cutting the concrete to run the line? If not what is the process?
Thanks,

Before cutting concrete consider hiring a horizontal driller (AKA "directional drilling") to bore under the slab. Circumstances permitting: the exterior is not hardscaped, a driller is available (with limited access equipment if necessary), the new gas line will require two access holes only (less mess and patching than the other option).

BTW, sizing and installing the gas line should be hired out to a qualified contractor. Doing so on your own, and without a permit, is foolish.

If the slab must go: saw cut the top 1" with a diamond saw (wet or dry [preferably wet with a wet or dry vacuum]) to within 2' of the exterior wall, drill 1/2" holes at all four corners to stress relieve the concrete, then break with a paving breaker. (A hole can be drilled under the remaining section with a standard garden soil drill).

Before cutting or breaking it's a good idea to: tightly mask all cabinets with plastic, then drape plastic from the ceiling to floor to encapsulate the room. During the breaking operation protect the base cabinets, windows, and other valued items with heavy cardboard.
