Wall Cracks


Wall cracks are a common indicator that something is occurring in the foundation of your home. When you notice wall cracks starting to appear in your home, it usually means that your foundation is moving. The only good thing about these cracks is that they can actually be a hint of the problem you are experiencing. Here is a list of the different types of cracks and what they mean:

  • Angled or Horizontal Cracks – Bowing
  • Angled Only – Settlement or Sinking
  • Combination of  Vertical and Horizontal – Bow or Settlement
  • Center Converging – Bow or Settlement
  • Horizontal Only – Bowing
  • Stair Steps – Heaving or Settlement
  • Vertical Only – Heaving or Settlement
  • Wider at the Top Vertical – Side or Differential Settlement
  • Wider at the Bottom Vertical – Center Settlement

Causes of Wall Cracks

Wall cracks are definitely a signal that something is going on with your foundation. Most cracks are due to the following problems:

  • Foundation Settlement: Settlement occurs when there are weak bearing soils, poorly compacted soil, changes to the level of moisture in the soil, or soil consolidation beneath part or all of your foundation. If the soil beneath your foundation can’t handle the load property, settlement is likely to occur.
  • Bowing and Leaning Walls: Bowing and leaning walls occur when pressure is exerted on the walls from the outside. When water levels are high in the soil this causes hydrostatic pressure to build up. It will push in on walls, causing them to bow, lean, crack, and even leak.
  • Heaving or Shifting and Moving: When there is a fast freeze or thaw, the ground can actually heave, shift, or move very quickly. There might be rapid expansion of the soil and the concrete that is above the expanding soil will heave, causing cracking in the walls.

You might also notice cracks in floors, tiles, ceiling, garage columns, slabs, foundations walls, steps, stoops, porches, drywall, and joints. These are all common signs that your foundation could be in some serious trouble and that you need to get in touch with a foundation repair specialist right away.

Solutions for Wall Cracks

Wall cracks can be fixed with polyurethane crack injections. Foam resins can be injected into cracks to seal them. The foam will expand to fill the crack and form a bond to prevent water from leaking through in the future. Underpinning solutions may also be required. This is why we recommend that you use the resources of My Foundation Repairs to find a foundation contractor in your area.
