What would cause water to migrate up through a slab and “sidewalk”?
We have lived in a slab Foundation house for almost two years. When it rains after a dry period we will have enough water come up through slab that it takes a squeegee to get it under control. This happens right at the carport door entry and about a foot away from a half bath wall, as well as into the first six or seven feet of parking area.
My first guess is that the downspout was directed into a pipe that may have been routed under the slab and that has failed somehow. We have noticed it more since we had the well housing and pipes raised to stop sediment from getting into our water lines.
Any ideas or suggestions in problem solving would be greatly appreciated
