What causes foundation problems, and could you have prevented yours? When something goes wrong at home, you replay every decision hunting for the moment you messed up. Also known as “Why is this happening to meeeeeee?” Syndrome.
Foundation problems are no different. That “why” hangs in the background, even though knowing the answer won’t undo the cracks. It’s human curiosity, and it’s completely normal.
Good news: we can answer it. Anchor Foundation Repair has been diagnosing foundation problems (and fixing them) for friends and neighbors across Bryan, College Station, and the Brazos Valley since 1985.
Below we cover three things: what causes foundation problems, whether you could have prevented them, and how to decide if yours needs repair. Spoiler: most of this isn’t your fault.
What Causes Foundation Problems?
Foundation problems in Central Texas come down to a recipe with two main ingredients. Mix the expansive clay soil under your home with our wild swings of weather, and you get a reliable recipe for foundation movement.
Yes, we’re cooking in a kitchen now. Stay with us.
Ingredient 1: Expansive Clay Soil
East of I-35, expansive clay soil dominates the landscape. This is the main ingredient, and it earns its name from how it behaves: it expands and contracts depending on how much moisture it’s holding.
The easiest way to picture it is with a room full of balls. So here we go.
Medium Moisture Levels
Picture a room filled halfway with not-quite-inflated balls. Those are your clay molecules. Now squeeze two walls together like the trash compactor scene where Luke, Leia, Han, and Chewy almost get flattened in Star Wars®.
Since the balls aren’t fully inflated, they squish together tightly. Keep pushing the walls until it’s nice and snug. That’s a medium moisture level: not too wet, not too dry, but just right.
Oh great, now Goldilocks is in the kitchen too.
Wetter Moisture Levels
Now inflate all those balls at once. This is where it gets interesting.
Packed in tight, the molecules can’t push out sideways, so they push up into the space above. That space happens to be where your foundation sits. During rainy seasons, that upward force lands on your foundation with real power.
Can you visualize what I’m sayin’ here?
Drier Moisture Levels: aka Summer, aka Drought, aka the 10th Level of Hades
When it’s dry for weeks with no rain, the clay molecules shrink and deflate, and your foundation drops along with them.
Deflate every ball in the room until they’re loose and saggy. The whole level sinks, and so does anything resting on top, like your foundation.
Now repeat this lift-and-sink effect through the seasons, year after year. Your foundation slowly weakens, sometimes cracks, and shifts from its original spot. In the industry, we call that settlement.
The forces of expansive clay are like daylight savings time for your foundation: springing up every wet season, falling back every dry one. Wait, this kitchen has daylight savings too?
Ingredient 2: Climate Conditions
The second ingredient is our delightful Texas weather. We get long stretches of heavy rain, then nothing. Like none, for a long time. Welcome to Texas.
Because our wet and dry seasons run kind of intense, our soil acts a little manic-depressive. Some seasons it’s lifting and powerful, busy messing with your foundation. Other seasons it slumps down, sad and sinking.
Enough to make any local foundation, well, crack up a bit. And yes, the manic-depressives are now in the kitchen, eyeing Goldilocks with mild contempt.
If our climate stayed consistent, the soil would too, and none of this would be much of a problem. But welcome to Texas, where “inconsistent climate conditions” is our three-part middle name.
Could You Have Prevented Your Foundation Problems?
Could you have prevented your foundation problems? Now that you know the soil and climate follow a predictable-ish pattern, it’s fair to wonder. Well, maybe. But probably not.
Two things are out of your hands. You can’t change the soil, and you can’t control the weather. The one variable you can nudge is moisture, so let’s talk about that.
Thoughts on Watering Your Foundation
You may have heard you can “water your foundation” to keep moisture steady. You can try it (we can’t stop you), but matching your wettest-season moisture all through a Texas drought is nearly impossible. We’re talking a swampy mess and a sky-high water bill.
Opinion alert: this technique works better in other climates. If you live somewhere with different soil or steadier weather, don’t rule it out. Here in Central Texas, though, it barely moves the needle.
Our best suggestion: water your grass and landscaping like normal to keep them alive, and stop there. You’ll get some moisture consistency without sending your water usage into orbit.
You Are Not to Blame for Your Foundation Issues
Here’s the part you came for: this is not your fault. The strong forces of expansive clay and our climate will win out over any small-scale watering effort, so don’t chase some impossible ideal of perfectly consistent moisture. Keep your plants and grass alive, which is what you’d do anyway.
Now that you understand the specialness of our soil and weather, know there was little you could have done to prevent foundation problems in Central Texas. Yay, this one’s not on you!
It might be your fault (or possibly your parents’ fault) if you’re hanging out in your kitchen with the cast of Star Wars®, Goldilocks, and some manic-depressives living on daylight savings time. But we’ll save that one for your therapist.
How Do You Decide If Foundation Repair Is Needed?
Deciding if foundation repair is needed isn’t a clean pass/fail test. You can’t dodge the dirt or the weather, so some movement and settlement are simply expected, and it’s often no big deal. So how do you tell a big deal from a no-big-deal?
Tough question, and there’s no tidy bulleted answer with hard measurements. It’s hard to define in exact numbers. But we know it when we see it (or hear it). Here’s what tips us off in either direction, and how to think about settlement versus real problems.
When Foundation Repair Is Not Needed
Settlement happens, and it leaves small flaws in your otherwise perfect home. These are the things you notice because you live there every day, but they don’t really bug you. A guest wouldn’t spot them, wouldn’t think twice if they did, and wouldn’t judge your home over them.
“I think of normal settlement as more like small hairline cracks in walls or drywall tape joints that ripple or shear just a little. A slight separation at brick frieze that could use just a touch of caulk and paint. A mortar crack that is so small you almost don’t even see it. Window separation you don’t notice until up close.”
-Craig Tripp, Anchor Foundation Repair President, Owner, CEO, Foundation Repair Extraordinaire
There’s no measuring stick here. No “X inches means settlement, Y inches means repair.” No pass/fail ruler exists for this.
Little flaws that don’t affect how your home functions land in the “to be expected” range and usually don’t need repair. Your doors still open and close, you can caulk the trim, and you need a magnifying glass to find that mortar crack. All is well.
When Foundation Repair Is Needed
The “normal settlement” line gets crossed when the problem starts affecting how your home performs. Is it still keeping you safe, secure, warm, and dry?
And just as important, is it doing its job to make you feel safe, secure, warm, and dry? Notice that word, feel.Deciding when a foundation needs repair often comes down to how the homeowner feels.
A few examples of things that cross the “failing to perform” line (not an exhaustive list, in no particular order):
- Cracks in walls that look “scary,” so you don’t feel safe
- Doors that won’t lock, latch, or close, so you’re not safe or secure
- Brick separation or cracks letting in air, water, and bugs, so you’re not warm, dry, or bug-free
- Anything a little caulk and paint can’t cover, so you don’t feel happy with your home
“We also cross that line when the owner starts to have reasonable doubt, worry, or unhappiness with their home. These things are more feelings-based vs. an engineering amount of settlement that is acceptable or unacceptable by some measurement.”
-Craig Tripp, Anchor Foundation Repair President, Boss Man, Bill Payer, Foundation Repair Master
Why the Answer Differs from Homeowner to Homeowner
Sometimes there’s no clean “pass” or “fail” because homeowner tolerance is part of the equation. The call depends partly on opinion and how you feel about the problem.
According to The Foundation Repair Master (nope, not letting that title go), the line between settlement and failure is fluid. Everyone’s tolerance for physical flaws, performance flaws, and general home feelings is different.
Maybe some deeply philosophical sayings will help:
One man’s crack in the wall that must be fixed is another man’s “meh.”
or
One woman’s not-locking door is another woman’s “oh well, we live in the country.”
or
One child’s arachnophobia is another child’s “yay, bugs are my friends and I want to be an entomologist when I grow up.”
Follow me for more terrible sayings that will never make it into the common American vernacular.
Feelings Matter in Foundation Repair, but So Do Professional Opinions
If that last section didn’t make it clear: your feelings are a real part of choosing foundation repair. Still, even after this compelling, wisdom-packed narrative, some homeowners won’t feel solid in their gut call and will want a professional opinion. Fair enough.
So here’s where you land. You now know foundation problems come from our expansive clay and swinging climate, that there’s little you could have done to prevent them, and that the repair decision blends real performance with how your home makes you feel.
Guess what? We’re full of professional opinions, with 40+ years of experience assessing and repairing foundations across the Brazos Valley. It would be kinda weird to call ourselves Anchor Foundation Repair otherwise.
Your next step: confirm what you’re seeing is actually foundation-related by learning the true and false signs of foundation problems. When you’re ready for a set of expert eyes, we’re here.
P.S. Maybe book a therapist appointment to process everything that happened in this article. Or maybe that one’s for us.
