How to Identify And Repair Bowing Foundation Walls

Walls Caving In? How to Spot and Solve Bowing Walls - Image 1

We’ve all heard the phrase “the walls are caving in” to describe feeling under pressure or a lot of stress. But what if the walls in your basement are actually caving in? Now that’s stressful! Don’t worry quite yet, if caught early, this foundation problem can be solved to protect your home from buckling down both now and in the future. Keep reading to learn how to spot signs of bowing walls and the solutions offered to address them!

Signs of foundation wall problems to watch for

Foundation problems can occur for different reasons. Fortunately, your home throws up red flags in several distinct ways:

  • Wall Cracks. Both horizontal and stairstep cracks can be a sign walls are beginning to bow. This sign often occurs on walls built with concrete blocks, where you can likely notice diagonal cracks between blocks.
  • Tilting. When the top of a wall begins to lean inward, it is affected by the soil pressure surrounding the home and may require repair. Tilting can also cause doors and windows around your home to stick or refuse to close.
  • Bowing. When a wall begins to weaken and get pushed inward, it displays a curve or bulge in one section of the wall, revealing bowing in action.

Walls don't crumble overnight and it can take years for these small warning signs to result in major structural damage. But these red flags are not something to ignore. If you spot these signs in your home, it is important to contact professional help as soon as possible! Catching a foundation problem early can save you a ton of money and headaches in the long run.

Causes of Caving Walls

Bowing and cracking basement walls are ultimately caused by what's happening outside your home within the soil and water

Pressure builds up in the soil surrounding basement walls, causing them to cave in over time.

Clay soil surrounding your home and basement soaks up water like a sponge, expanding and puffing up. This swollen soil puts a lot of pressure on your basement walls - we call this hydrostatic pressure. Walls can begin to crack under pressure, resembling cracks like the ones in the photos above.

But the problem continues. When the ground outside begins to dry out, the soil shrinks back down, leaving weak spots around your walls. Then when the rain returns and the ground swells back up, walls caught in the middle become weaker and are pulled inward.

All this drama is caused by heavy rain, poor drainage, inadequate grading around your home, frost, and even tree roots. Your driveway and porch can also add to the pressure underground, causing serious damage in the long run.

Keeping an eye out for early warning signs like cracks or water sneaking in through the walls can help you catch foundation problems before they get worse. If ignored, the walls could fail, resulting in serious damage to the safety and structural integrity of your home.
