What steps , and type of professional's should I talk to , to find out if my foundation is being damaged? Any help appreciated , Thanks. Jing: We took a look at your photos of "cracks" in a poured concrete foundation.

Those are cold-pour joints. Indeed in some cases a cold pour joint can be a source of foundation leakage; if a foundation were also totally lacking in reinforcing steel mesh or re-bar, then a severe cold-pour joint might also be a structural problem.

I agree that if there is water entering the concrete then sealing the wall exterior might be a smart idea both to stop leaks and to stop or at least very much slow down serious rust damage to the steel reinforcement in the wall.

RE-posting May 10, Jing said: I am buying a house built in that has horizontal cracks in the concrete foundation in the crawl space. I asked a foundation consultant to do an inspection on the house. He checked the leveling of each room with his tool and also went to the crawl space to look at these cracks.

After that he told me the structure of house is fine and these cracks are hairline like and thus no concern. But I am still very concerned about these cracks becuase I see online many people say horizontal cracks in foundation can be problematic. As times goes the moisture can go into cracks and then the steel can have corrosion and expansion and finally the concrete foundation can collapse.

I have very little knowledge on house and thus would like to get a second opinion. I have posted some images about the cracks in the following website. BTW I think maybe some cracks are not hairline like.
