What Is Foundation Failure?
Foundation failure happens when the soil under your home can no longer support the weight of the structure. The foundation starts to settle, sink, crack, or bow. Left alone, the damage gets worse and the repair gets more expensive. Most residential foundation failure starts in the soil, not the concrete.
What Causes a Home Foundation to Fail?
Foundation problems almost always trace back to the soil and the water around your home. Here are the most common causes of foundation failure.
Evaporation and Dry Soil
In very dry conditions, clay soils shrink. Clay soil is common across the Chicagoland area. When it shrinks, it leaves gaps under your foundation. Without support, the foundation settles and sinks. The sinking often continues even after the dry weather passes.
Drainage Problems
Bad drainage from your gutters lets water pool around the foundation. The extra moisture makes the soil swell. The shifting soil then pushes on the structure and can lead to foundation damage.
Grading Problems
Poor grading around your home pushes water toward the foundation instead of away from it. This adds pressure against the walls and can cause them to bow inward. Over time that lateral pressure weakens the foundation.
Unsuitable Soil Conditions
Soil that was not compacted well during construction expands and contracts over the years. This movement causes the foundation to settle. Poorly prepared soil is one of the most common foundation problems.
Trees and Roots
Trees planted too close to your home can damage the foundation. Their roots pull moisture out of the soil and cause settlement. Large roots can also press against the foundation and make it crack or bow.
Plumbing Leaks
A hidden plumbing leak can wash away the soil under your foundation for years before you notice. The added moisture puts pressure on the foundation and can lead to cracks or failure.
Insecure Foundation, Framing & Poor Construction
If the foundation was not properly secured to the framing during construction, it can shift or lean over time. This leads to structural problems and eventual failure.
Common Signs of Home Foundation Failure
Catching the problem early saves money. Watch for these signs of foundation issues:
- Cracks in walls, floors, or the foundation itself
- Crumbling or flaking concrete on the foundation
- Doors and windows that stick or will not close
- Uneven or sloping floors
- Gaps around window and door frames
- Bowing or leaning foundation walls
- A chimney that tilts or pulls away from the house
How to Prevent Foundation Failure
You cannot control the soil under your home, but you can control the water around it. These steps help you avoid foundation failure:
- Keep gutters clean and extend downspouts away from the house
- Grade the soil so water drains away from the foundation
- Water the soil during long dry spells to keep it from shrinking
- Plant trees a safe distance from the foundation
- Fix plumbing leaks as soon as you find them
- Have your foundation inspected at the first sign of trouble
Does Homeowners Insurance Cover Foundation Failure?
It depends on the cause. Most standard policies do not cover gradual settlement from normal soil movement. They may cover damage from a sudden, covered event such as a burst pipe. Read your policy and ask your provider about your specific coverage before you assume you are protected.
