Structural Concrete Wall Damage

These exterior concrete walls are a good example of poured in place concrete walls. These walls would have been poured in sections, over a few days, without rebar reinforcement. This type of construction is no longer allowed because of problems like the ones you're looking at.

The large crack in between the two windows on the left side of the picture that runs horizontal are definitely major structural crack.

This crack looks like it runs all the way through the wall and could be creating a structural hinge point. The window frames could be all that is holding up these walls at the moment.

Sometimes you can take photographs and send them to a structural engineer for a property evaluation. This might not cost as much money and could save the engineer a trip to the property.
