Bowing Foundation Walls & Sinking Floors
Basement walls will usually begin to bow before you can see any cracks. This bowing is sometimes difficult to see, but any bowing at all is an indication of a weakened structure. This can be from the external pressures on the foundation, and it’s only a matter of time before this cracking shows on the inside of the basement. Brick walls are just as vulnerable to bowing and cracking as concrete and are also susceptible to crumbling mortar.
Bowing of basement walls is a serious problem and must be addressed before the problem becomes irreparable. Although it is sometimes difficult to see bowing walls or sinking foundations when they begin, there are other signs that help you catch problems before they arise.
Look for these signs:
Cracks in the walls that are wider at the top than at the bottom- Floors that are not level
- Doors, cabinets and windows that do not shut properly
- Cracking in the upstairs plaster and/or drywall
- Cracking in exterior brickwork and/or caulking
- Leaning of outside chimneys and/or porches
