Hello. I’m in need of some advice. I’m in the negotiation phase with a builder for a new home which is being built as spec. The foundation was poured about a month ago and the house has been framed and roofed. I walked into the basement this evening to take a look around and saw the attached small cracks. Note - Chicago got some heavy rains over the last few days and there’s no windows anywhere. The full basement will be finished with carpeting. Should I be concerned? Should I approach the builder to repair and/or fill? These appear to be about 1/16" in size. Any help would be very much appreciated. Thank you!
