Horizontal Cracks In A Basement Foundation Wall This discussion relates to cracks in the concrete foundation wall for a house with a basement. This is not relevant to slabs on grade or to cracks in walls above grade level. A horizontal crack in a foundation wall, below grade, which runs the length of the basement, is likely a sign that the foundation is failing under the weight of the surrounding soil. The soil outside the foundation wall exerts an enormous pressure on the foundation wall. Foundation walls are designed to be strong enough to resist this load. Occasionally, unanticipated, additional loads exert pressure and the foundation begins to fail, resulting in a horizontal crack in the foundation wall. Settlement Cracks Foundation settlement cracks are vertical, extending up through the structure. For a brick home, you may see cracks following the mortar joints in the brick wall. In most cases, the settlement crack itself has no structural significance. Rather, we are concerned that the house could continue to settle over time. Most settlement cracks are the result of short- term settlement. Ongoing settlement is unlikely and uncommon. Unfortunately, it is very difficult to identify ongoing settlement from a one- time visit to the home. Since multiple visits to the home over a few years is not compatible with a real estate transaction, we have to use our experience to âread the cracksâ and take an educated guess as to whether ongoing settlement is likely. Settlement crack size: A larger settlement crack is more likely to be due to ongoing movement than a smaller settlement crack. While there are no hard and fast rules, a settlement crack or series of settlement cracks that have a sum total opening of less than 1/4 inch are probably not due to ongoing settlement. Direction of movement: A typical settlement crack is vertical, where the crack opens up. The bumps and crevices line up and fit together like the pieces of a puzzle. ![]()
If the crack face has moved in any other directions, such as a shear crack, the quarter- inch rule described above does not apply. This can be a significant structural concern. Repaired and re- cracked: A settlement crack that has been repaired and has re- cracked (not just a hairline crack) also could indicate ongoing movement.
