Sagging Floor Evaluation in Greenwood, IN
Where floors sag in older Greenwood housing, the cause is usually beneath the basement slab rather than in the framing. The main girder is carried by a line of steel columns, each sitting on a footing pad, and those pads bear on the same clay that surrounds the house.
Clay has a property that makes this specific: its bearing capacity is a function of how wet it is. A pad that comfortably carried its column for thirty years can begin to settle after a plumbing leak, a failed sump, or a persistent seepage path softens the soil directly beneath it. The load did not change; the ground stopped being able to carry it.
That is why the first question about a dropped column here is not how much load it carries but what has been wet near it. A structural fix applied over a moisture cause tends to be a temporary fix, and the sequence — find the water, then correct the support — is not interchangeable.
What We Look At Here
- Floor elevations along the girder line to locate the actual low point
- Column base condition: settlement, corrosion at the slab, and bearing area
- Evidence of past or present water near each column footing
- Sump operation, discharge routing and any history of failure
- Girder size and span against the load it carries, to rule out simple overload
- Whether basement finishing added walls or loads the original beam never carried

Questions
Frequently Asked Questions
One basement column in my Greenwood house has dropped. Why just one?
Most often because the soil under that particular footing was softened by water — a leak, a seepage path, or a sump discharge. Clay loses bearing capacity when wet, so a single wet spot produces a single settled column.
