Crack in Foundation

A section of the foundation of this house has broken loose, causing an extensive series of horizontal cracks.

Failed Rebar

When a basement is built, they use snap ties to hold the forms and the rebar together. Sometimes, water migrates through an opening in the concrete around one of the ends of the snap ties and reaches the rebar. The water causes the rebar to expand—up to seven times the original size—causing the concrete to blow out.
