Not being a wise guy, sometimes one has to cut to losses. The lateral movement is not the problem but a product of under laying materials.
I agree with the above that wheel loading together with basement soil, base rock (hopefully not sand), and/or water intrusion is the problem.
The concrete is most likely starting a long slow process of moving about and failing.
I have only seen the solution to be to pulverize and use the existing as crusher fodder to build up the structural section upon which to construct a correctly designed drive.
If the under laying soil is clay or high in organics or located on the vicinity of a spring you will need to de-water with french or under drains.
I offer this not to distress, but as an honest opinion.
