What does a structural engineer look at in St. Clair County?

St. Clair County ranges from Belleville's nineteenth-century brick to new construction around O'Fallon and Shiloh. As in Madison County, old coal mines run under parts of it, so cracks and sloping floors are read with that in mind.

What is different here

  • Old coal mines. Subsidence is a known cause of damage here, and its pattern differs from soil settlement.
  • Belleville brick. One of the largest groups of old brick houses in the state, with the masonry questions that come with age.
  • Newer subdivisions. Poured basements near Scott Air Force Base, often inspected for buyers on a short clock.
  • Illinois seal. Reports and letters for these properties are sealed for Illinois.
