My apologies, the original message was not very helpful. After heavy rainfall, we noticed approximately 1/8" cracks in the floor of the garage. These radiating out from a point near the front center of the garage (away from where cars are parked) and extend to each wall. The cracks appear to be approximately 1/8" deep as well. This is split level construction - the garage is located at ground level and a slab foundation was used. I have not noticed drywall cracking or any tightening of doors or windows.
