What Causes My Home’s Foundation To Sink Or Move?
The word foundation itself should reveal to you how crucial it is to your home. Your home’s foundation serves as the load-bearing base of your home, located just beneath the surface, that keeps the entire structure stable and level. It’s normal for the foundation to experience minor shifts as the soil underneath settles, but more significant movement can jeopardize the entire building’s structural integrity.
So, what causes a home’s foundation to sink? Numerous single or combinations of factors and conditions can lead to foundation damage, including the type of soil beneath your house and the amount of moisture it retains.
Recognizing the underlying causes of foundation movement is essential not just for safeguarding your investment but also for ensuring a safe living environment.
In this article, we’ll explore the key contributors to foundation problems and provide insights to help you protect your home from potential pitfalls.
Reasons Why Your Foundation Is Sinking
While it’s not a good thing, it’s also not unheard of for pier and beam or concrete slab foundations to suddenly be uneven, sink, or settle. Otherwise, there wouldn’t be a need for experts like us at Xpert Foundation Repair, and we’re busy all the time.
Here are some of the more common reasons why foundations sink.
Home Sits in a Drainage Point in the Area
Living in a home that sits at a drainage point can significantly impact your foundation’s stability. This unique positioning in the geography of the area often means that your home is more susceptible to foundation issues due to irregular moisture levels.
Maybe you’re on a slope, in the middle of a valley, or the homes right next to yours are higher up, and their excess water is draining toward your home.
When excess water consistently accumulates around your home, it can disrupt the stable soil that supports your foundation, leading to uneven settling or even sinking.
It’s crucial for you to feel secure in your living space, knowing it stands on solid ground. Therefore, addressing these moisture-related challenges becomes essential.
Implementing better drainage solutions can mitigate these risks. Consider regrading your property to encourage water flow away from the foundation or installing a more effective and proper drainage system.
Poor Soil Conditions
Poor soil conditions often lead to foundation sinking, a major concern for any homeowner. Some soils, like expansive clay, swell when wet and shrink when dry, creating movement beneath your home that can cause significant damage over time.
You might wonder why some areas are more affected than others. Well, soil composition varies widely from place to place. If your community is built on soil that isn’t stable, you’ll likely see signs of distress in the homes around you as well.
Addressing these issues might seem daunting, but recognizing the problem is the first step toward fixing it. Understanding that poor soil conditions are a common issue can help you feel less isolated as you take action.
Don’t hesitate to reach out to professionals who can assess the severity of the damage and offer tailored solutions. Remember, you’re not in this alone.
Natural Disasters
Natural disasters, from earthquakes to floods, can severely impact your home’s foundation. When the ground shakes or becomes overly saturated, it puts unexpected pressure on your foundation. This can lead to cracks, shifts, and even collapse if not addressed promptly.
Many homeowners face these challenges, especially in disaster-prone areas.
Extreme Weather
Extreme weather events, such as severe storms and prolonged droughts, can critically undermine your home’s foundation. When you’re facing these conditions, it’s not just the weather you’re battling but also potential damage to where you live.
Heavy rains can saturate the soil, causing it to swell and exert pressure on foundation walls. This can lead to bowing or cracking, signs you might notice if your doors begin to jam or fail to close properly.
Conversely, droughts can be just as detrimental. The soil dries out and shrinks, pulling away from your foundation and creating gaps where your home may settle unevenly.
Age of Structure
While extreme weather conditions pose significant risks, the simple passage of time also plays a pivotal role in the sinking of your home’s foundation.
As your house ages, the materials used in its construction naturally deteriorate. This process isn’t just about the bricks and mortar; it extends to the very earth—the dirt beneath your home. Over time, this dirt settles and shifts, a phenomenon that can be exacerbated by the weight and pressure of your house pressing down year after year.
This gradual movement mightn’t be noticeable at first, but it can significantly impact the integrity of your foundation.
Think about it: the older your home, the more likely it’s that you’ll start noticing doors that won’t close properly or cracks appearing in walls or floors. These are telltale signs (which we’ll detail more later) that your aged foundation might be moving.
Bad Construction
Many foundation problems stem from poor construction techniques or materials. When the crew building your home cuts corners or uses subpar materials, it’s not just an aesthetic issue—it affects the very stability of your place and poses serious safety risks down the line.
The use of inadequate concrete or improper soil preparation can directly impact the integrity of your foundation. It mightn’t be obvious at first, but over time, the foundation begins to settle unevenly and eventually leads to house sinking.
To bring back your peace of mind, it’s crucial to address these construction flaws.
Warning Signs That Your Foundation Might Be Sinking
If you’re noticing foundation cracks or unusual diagonal drywall cracks, it’s time to pay attention.
These signs, along with others, might mean your foundation is sinking.
Foundation Cracks
A visible crack on your slab foundation is one of the top signs that your home’s base might be sinking. It’s unsettling to discover these signs, as they not only suggest your home is shifting but also that you’re facing a potentially serious issue that needs addressing.
These cracks can vary in size and appearance, but all point to the same underlying problem: the ground beneath your house isn’t holding up as it should. It’s a common issue, especially in areas with unstable soil compositions or excessive moisture.
Addressing these signs early can prevent more severe damage. So, if you see foundation cracks, it’s crucial to act swiftly.
Diagonal or Unusual Drywall Cracks
Diagonal or unusual drywall cracks are clear indicators that your foundation may be experiencing issues. When you notice these jagged lines creeping across your walls, it’s a sign to take a closer look at what’s happening beneath your feet.
These cracks often stem from shifts in your foundation, which can be exacerbated by the type of soil around your home. Particularly, clay soils are prone to expanding and contracting with moisture changes, exerting uneven pressure on your foundation.
Cracks can also appear near window frames, where the stress is often more pronounced due to the rigidity of the frames themselves. This is a sign that the surrounding foundation is moving, and the non-flexible steel window frames can’t adapt to these changes.
Every step you take inside your living space might feel unchanged, but beneath the floor, there’s a gradual, relentless movement that’s pulling at the seams of your house.
It’s crucial to monitor the extent and direction of the cracks. A small crack might seem innocuous, but it’s often the first whisper of a larger conversation your home is trying to have with you.
Don’t ignore it.
Cracks in Foundation Walls in Basement
You might find alarming cracks in the walls of your basement, which often signal that your foundation could be sinking and putting the structural integrity of your living space in jeopardy.
These visual cues are critical in understanding the health of your foundation.
Bulging Patches Of Lawn Or Concrete
Amidst your regular yard maintenance, if you notice bulging patches on your lawn or concrete, take heed—these could be signs that your foundation is shifting.
This bulging can result from the soil expanding underneath due to moisture absorption. It’s a common issue, especially in regions where the soil composition fluctuates with the weather, alternating between dry and wet periods.
Uneven Floors In Your Home
If your home’s floors feel uneven as you walk across them, this may signal a sinking foundation. It’s an unsettling feeling, isn’t it?
This common issue often stems from soil issues beneath your home that cause the foundation to settle unevenly.
You might start seeing small gaps where your floor meets the walls, or perhaps your once smooth floors now have a gentle slope.
One common way to make sure is to place a ball, marble, or anything that can roll multiple ways on the floor and then see if it rolls or “sinks” to another area of the floor.
This will be a clear indicator.
Opening Doors And Windows Is Difficult
Many homeowners find that doors and windows that once opened smoothly are now stubborn and difficult to manage. This common issue often points to a deeper, more serious problem—your foundation might be shifting.
When your foundation moves, it can warp the frames of doors and windows, making them stick or not fit properly in their frames anymore. It’s like your home is slowly changing shape around you. If you’re struggling with doors that won’t close without a good shove or windows that stick, even after fixing any hinges or accounting for humidity, it’s smart to take action sooner rather than later.
Gaps Around Doors and Windows
In addition to doors and windows that are difficult to open, you might also notice gaps forming around these features, signaling potential foundation sinking.
These gaps often appear as uneven spaces where your doors and windows no longer align with their frames. It’s a clear indication that your house isn’t just settling; it could actually be shifting. The gaps can widen, pointing towards more severe structural damage if not addressed.
As you observe these changes, it’s important to connect with professionals who understand your situation. They can offer solutions that prevent further damage and restore your sense of security.
Excess Moisture in the Basement or Crawl Space
Excess moisture in your basement or crawl space isn’t just a nuisance; it’s a major red flag for potential foundation problems. When you discover water pooling or damp patches, it’s essential to take action.
This is a common issue, especially in areas with high rainfall or poor drainage. This unwanted moisture can weaken the soil beneath your home, causing it to shift or settle unevenly.
Imagine the ground under your home like a sponge; when it gets too wet, it can no longer support the weight above it effectively. That’s when you might start noticing cracks in walls or floors, doors that won’t close properly, or even tilting chimneys.
Common Foundation Repair Techniques
Now that you understand the warning signs, it’s crucial to explore how you can address foundation issues like foundation sinking.
Each method targets specific problems, so choosing the right one is essential for effective sinking foundation repair.
Helical Piers
When dealing with foundation issues, helical piers are one of the most effective methods and go-to solutions for stabilizing and lifting sinking structures. These tools, akin to giant screws, are driven deep into the ground until they reach stable soil, ensuring a solid base to support your home.
Many homeowners opt for helical piers because they’re not only effective but also minimally invasive compared to other methods. They can be installed quickly, with little to no disruption to your daily life.
Plus, they’re versatile, working well in both light and heavy structures, which makes them a popular choice.
Helical piers also bring longevity to the repair process. Once they’re in place, you can rest easy knowing that you’ve chosen a durable solution that prevents future issues.
Push Piers
Another effective method to consider for foundation repair is the use of push piers. Push piers, also known as resistance piers, are a popular choice, especially when your home’s foundation requires robust support.
Push piers are driven deep into the soil beneath the foundation until they reach a stable soil layer or bedrock. This process not only stabilizes but also has the potential to lift your home back to its original level.
What’s great about push piers is their minimal disruption compared to other methods. They’re installed directly beneath your home’s support, requiring less landscape alteration and quicker installation. This means you can fix your sinking foundation without turning your daily life upside down.
Moreover, push piers are designed for heavy loads, making them an excellent choice for parts of your home that carry significant weight. With push piers, you’re not just repairing your home; you’re investing in peace of mind, knowing that your sanctuary stands solid.
Slab Piers
Slab piers are another essential strategy for addressing concrete slab foundation issues. These sturdy, supportive structures dive deep into the earth beneath your home, also anchoring into more stable soil or bedrock, which provides a firm base to correct and prevent further sinking.
This method involves driving steel or concrete piers through the unstable soil layers until they reach a depth where the ground is stable.
Once these piers are in place, the slab is carefully lifted and supported evenly, ensuring that your home stands firm against the forces of nature.
Plus, slab piers not only help solve the immediate issues but also act as a preventive measure against future problems.
Shimming or Jacking
Shimming or jacking is a common technique used to address specific foundation problems.
- Shimming involves inserting small pieces of material—often metal or plastic—under your home’s foundation to level out uneven areas. Think of it as slipping a wedge under a wobbly table leg; it’s a simple yet effective way to achieve balance.
- Jacking is a bit more intensive. This process uses hydraulic tools to lift your home’s pier and beam foundation slightly, allowing for the installation of supportive piers or jacks underneath. It’s as if you’re gently picking up a sagging couch to put a firmer cushion beneath it.
