Our house is under construction at early stage. The poured concrete foundation wall was finished two weeks ago. I find many small cracks (about fifteen) on the surface of the concrete wall, and most of them pass through the reinforcing bars. (I guess that the builder did not put enough water in the concrete.) We see some of cracks have gone a couple of inches down from the top of surface. Will these cracks continue going down? Will they cause any major problems in the future?
Would you please kindly give us answers to these questions, and give us some advice on what we should do?
