Hey all, looking at a house for a friend. Seems like an extra skim coat was applied to the basement slab after construction on this 15 year old model home in the Chicago area. It’s flaking up and chipping in several areas, to where you can pick up a 10 inch section off the ground, exposing the slab below. Multiple damp foundation cracks as well.
I suspect its a bad/cheap foundation and slab pour, given its the first home built in a cookie cutter subdivision in one of the lower elevations in the county, leading excessive moisture to pass through the slab and separate the skim coat. Thoughts?
