Floor Cracks 

Floor cracks often appear in homes with concrete slab foundations. When these foundations experience settlement and sinking, it causes the non-flexible concrete to crack.

Have you noticed a large crack across a concrete garage floor or somewhere inside your Austin or San Antonio home? This is a sure sign of foundation damage, and it shouldn’t be ignored. If your home rests on a concrete slab foundation, there’s a likely chance that you will experience this problem sign. Thankfully, FSS has solutions designed to protect your home from this very issue. Read on to learn more about what causes this problem sign, and how you can fix it. 

The Importance of Foundation Cracks

There are a number of reasons why you should be concerned about cracked floor slabs around your house, even if a few cracks may not seem like a big problem. Cracks in your slab floor can begin as hairline cracks and grow larger and larger, eventually presenting a tripping hazard. Regardless of size, floor cracks are primarily a symptom of damage and instability in your home. They are a warning sign that all is not right beneath your floors.   

Slab floor cracks at your San Antonio or Austin home indicate a structural problem that won’t fix itself and will only get worse with time. If you notice floor cracks, be sure to do a full inspection of your home’s foundation, both inside and outside. Look out for other structural problems like: 

  • High Indoor Humidity 
  • Uneven Floors 
  • Gaps in Walls and Doors 
  • Tilting Chimney 

If you’re having any doubts as to the structural integrity of your home, it’s best to have an expert from FSS access your foundation. The inspection is free and no obligation. The longer you wait, the more costly the repairs could be. Schedule your free inspection today.   

What Causes Floor Cracks?  

Floor cracks are a symptom of foundation damage, which is caused by problematic soil. Here’s the most common soil issues your concrete slab will have to contend with.

Soil Washout 

Rainfall isn’t as common an occurrence in Austin and San Antonio as it is in other parts of the country, but when it does come, it causes issues for the soil in your yard. Most often, precipitation causes your soil to become eroded, soft, and muddy. Soil particles may also be washed away as the rainfall drains around your yard. As soil washout makes the ground around your foundation weaker, it may cause the concrete slab to sink into the ground. Since concrete slab foundations are not flexible, floor cracks inevitably appear.

Expansive Soils 

Clay soil is common throughout Bexar and Travis County, making up a majority of the soil content in this particular region of Texas. Something to keep in mind about clay soil is that it expands when it absorbs water. While Austin and San Antonio both receive below average amounts of yearly rainfall, even just a little bit of rain can cause clay soils to expand. Expansive soils wreak havoc on the floor of your home, especially in a home with a concrete slab. As the soil expands, it pushes up onto your foundation and causes the floor to split.

Dry Soil and Drought  

Being located in Texas, we’re well aware of the dry and hot environment of our state. We also know how much these dry conditions impact the soil in your yard. When soil suffers from a lack of moisture, it shrinks in volume and becomes brittle to the touch. As the soil shrinks, a gap forms between your foundation and the ground. Gravity forces the foundation to collapse into this hole, and a floor crack may form. Moreover, the brittle nature of dry soil cannot withstand the weight of your foundation. This causes even more settling as your foundation crushes into the weak soil, causing more cracking.

FAQs

Unfortunately, fixing cracks in your concrete floor is no simple task. DIY solutions such as caulk or cement coatings won’t solve the main cause of the issue – problematic soil. While these store-bought solutions might make your floor crack look better, the soil below your home will still cause damage in the future. Eventually, these DIY solutions will break down as well, costing you time and money. Contacting FSS for professional foundation solutions is the best way to ensure that floor cracks are fixed efficiently and permanently. Solutions such as slab piers and push piers are designed to prevent soil from ever damaging your home in the future.  

Floor cracks are just one problem sign brought on by foundation damage, and often one of the most noticeable ones.

One you’ve seen floor cracks, looks out for drywall cracks, uneven floors, floor and wall gaps, and more.
