Are these interior cracks in garage normal? 3+ year old build.
This was a "cheap" build., concrete block with monolitch slab.. I doubt it was excavated before pouring the slab. But I do believe fill dirt was added and compacted. I first noticed hairline settlement cracks at about the three year mark. They were very minor, however the ones near the exterior of the garage did appear slightly "staircasing," That side of the house is on a grade, picture in comments. The garage foundation has no signs of cracks. I park my car in there.
I had the house repainted about 6 months ago, and the exterior cracks have not reappeared. On in the interior of the house.
The cracks of concern are in the interior of the garage, on the exterior walls, although there are cracks where the ceilings meet all the way around. I have posted pictures of the worst of them. They are definitely much bigger than a quarter in some areas.
Any suggestions would be appreciated. The slab is warrantied for 10 years. But it requires a engineer's inspection, which I don't have a problem doing.
