Weird conclusion from foundation engineer Had an engineer come over to look at some cracks. I live in a 1940s house with a full poured concrete wall foundation basement. New hairline cracks started appearing in the last 5 years (lived here for 5 years). Some on both sides of the wall (inside and out). Engineer stopped by, everything is plumb. However, the new cracks he said were new shrinkage cracks... Shrinkage cracks on a 80 year old foundation? He said that it happens all the time. Did i hire a boob for an engineer?
