My ranch style house is built on a slab over clay soil in N.E. Indiana. There are close to a dozen vertical hairline cracks visible in the base of the foundation at various points around the house (i.e. from the ground extending up to where the siding covers the concrete.
There are also hairline cracks in the drywall inside in several places and the linolium in the kitchen has a 3 or 4 foot line where it looks like the cement floor may be cracked underneath.
Is this something to have checked out? Other than cracks there is no obvious problem this is causing right now. Is it likely to get worse?
