Repair Off-Center Footings during Building ConstructionIt is sometime hard to position footings in the trench, so contractors often see walls that are not in the center of the footing (Figure 1). The foundation wall has to be located correctly to support the house, of course, so it has been placed off-center on the footing.
Figure 1: This incorrectly placed footing caused the foundation wall to be off-center. If the soil is very strong, this may not lead to problems. If the footing is on a weaker soil it is recommended that it is fixed.In good bearing soil, it is not the matter of much concern about this foundation for the loads involved in a simple wood frame house. The full width of the footing is not needed to support the loads; wall can be constructed right on the edge of the footing and still have enough support. However, if it goes over the edge and have the wall sticking out past the footing on the side or on the end, then rotational force is generated which the footing is not designed to handle. In that case, an engineer has to get involved. If soils are relatively soft, the risk is even greater.
