Sloped or Sagging Finished Floors Detectable with a Marble

A marble or round object that rolls consistently toward one wall of a room is physical evidence of floor slope caused by foundation settlement. Slopes of more than 1 inch over 10 feet are structurally significant and progressive.

NJ second-floor joists typically span onto load-bearing walls that sit on the foundation. When the foundation drops, the finished floor drops with it. Underpinning restores stable support and often allows partial re-leveling during the lift phase.
