What Causes the Need for Foundation Repair in Austin Homes and Businesses?

The integrity of every structure depends on a sound foundation. Small cracks and shifts in your foundation can turn into big problems in a hurry, especially here in Texas where our dry climate and expansive clay soils leave homes susceptible to foundation movement. Expansive clay soils respond to moisture changes at an extreme rate compared to non-expansive soils. High or low moisture levels result in the expansion and contraction of molecules, causing upheaval or settlement to the soil directly underneath the home’s foundation.

Blackland clay east of I-35Limestone shelf west of MoPacBalcones Fault splits the metroLate summer is crack season

Austin sits on a geological dividing line. The Balcones Escarpment runs roughly along MoPac and I-35 and splits the metro into two very different foundation environments. East of that line, the Blackland Prairie brings deep expansive clay that swells in wet winters and shrinks hard in July and August. West of it, the Edwards Plateau puts thin soil over fractured limestone, where the problem is usually drainage, slope and uneven support rather than heave. Which side of the line your home sits on is the first thing our technicians look at.

According to a study performed by the University of Texas at Arlington, the damages to infrastructure resulting from structural movement caused by expansive clay soils is close to 9 billion dollars per year! The threat of structural problems is very serious and very real in Central Texas. If you examine the expansive clay soil map and drought conditions provided by the US Drought Monitor, you’ll see that Austin is located right in the middle of a high-risk zone for structural damage.

austin-foundation-problems-map

The geological and weather-related evidence is validated by the high level of demand for foundation-related services in Travis County. According to Google Trends, a database that tracks Google search activity in various regions, Austin is among the nation’s top 5 most active regions for “foundation repair” search volume.

The takeaway: in a metro where foundation movement is this common, catching it early is the difference between a minor repair and a major one.

Unfortunately for property owners, expansive clay soils aren’t the only factor working against your real estate investment. Here is a more comprehensive list of issues that includes the top 5 most common causes of foundation problems in Travis County. This list was determined using data collected from Olshan customers in the region over the past decade.

Seasonal Weather ChangesPeriods of wet and/or dry climate can have a volatile effect on the soil underneath your foundation. As the soil expands and contracts, over time, the structural integrity supporting your home can weaken, causing the foundation to settle and crack.
Poor DrainageProper drainage management systems are an important component of a healthy home. Too much or too little water near the home can lead to stress. Standing water around your home, large amounts of water dumped by downspouts or a negative slope near the landscape around your home can all cause drainage problems to emerge.
Expansive Clay SoilsThere’s little that can be done to avoid the problems caused by expansive soils in Texas. It’s important to address any structural problems early, before the damage gets worse.
Trees and Tree RootsBelieve it or not, a large tree can consume as much as 150 gallons of water per day. When roots are under or near your foundation, the drying process may cause a portion of the soil to shrink. The differential in moisture content below the home may cause one part of the foundation to move more than others. Root barriers, tree removal and foundation watering can often help.
Under-Slab Plumbing LeaksLeaking water underneath the slab can create excessive moisture levels deep under the structure, causing the affected area to heave upward and disturb the stability of your slab. Under-slab leaks often go unnoticed. Hydrostatic testing is recommended to check for plumbing issues hidden deep below the property.
Wood RotThe wood used in crawl space homes can rot or warp, affecting the stability of the foundation. Central Austin’s pier and beam homes are the most exposed: poor crawl space ventilation and years of moisture soften sills, beams and joists until floors sag and doors drift out of square.

Other problems we commonly encounter include:

Lateral MovementSoil movement caused by erosion, sliding or sloughing of soils. Mudslides can be caused by lateral movement.
Soil CompactionSupport materials found underneath the property can fail due to compaction.
Frost HeaveThe water that accompanies the soil underneath the property can freeze, leading to expansion and upheaval.
Building DefectsFaulty design or construction during the building process can lead to failure.

Damage caused by structural problems should not be ignored, it’s important to fix the damage early, before it spreads. If you are seeing signs of trouble schedule an assessment with a Certified Structural Technician or reputable Structural Engineer.

How to Find Signs of Foundation Damage in Austin, TX

Regularly inspecting your home and foundation for signs of damage can play an important role in preserving the long-term performance of the home. Here’s a checklist of the most common signs of foundation problems.

Uneven, sagging or warped floors
Bowed walls
Cracks in walls and ceilings
Separation of baseboards from walls, especially at corners
Crooked doors and/or doors that won’t open/close properly
Cabinet doors that hang askew
Windows that stick (are hard to open and close)
Cracked chimney – improper exterior drainage may be the cause of chimney cracks
Cracks in exterior walls
Building corners that appear separated
Portions of the house that seem to be sagging into the ground
Pooling water or swampy spots in the lawn, especially near the foundation

If you live in Texas, make a habit to check for these items every year. The best time to walk your Austin home is late August or September after the summer dry-down, and again in March after winter rains. If you suspect you may have a problem, schedule an assessment. At Olshan, our staff not only fixes the damage, we also carefully investigate your property to discover what the underlying problem truly is. We don’t just mask the symptoms, we correct root of the problem to ensure a long-lasting solution.

4Plain-English findings.You see the elevation map and hear what it means. No pressure, no engineering jargon.

What is the Cost of Foundation Repair in Austin, Texas?

There is a lot of information on repair costs available online, but you’ll find that a lot of it includes data on basement homes and waterproofing. Although the extra space might be nice, basement foundations are just not that common in Texas. That can be a good thing though, as basement homes are vulnerable to a unique set of problems all of their own. What we do have are crawl spaces, and they present their own set of problems.

Here is a very basic outline for estimating cost:

  1. To establish a rough estimate you will first want to determine if you have a pier and beam, slab-on-grade, or base and block foundation.
  2. Next, a contractor will determine the extent of the problem. A large problem like upheaval will be more costly.
  3. The type of solution used will also impact the price. First, the contractor will need to determine how accessible the area that needs repair is. Tunneling underneath will often be more costly than other alternatives, like injecting the area between the slab and soil with polyurethane grout. If piers are used, the build materials and the number of piers used will affect the cost.
  4. Special considerations will also be made since each home is different.
  5. A repair plan is configured that may include other, related components, such as root barriers, drainage management or tree removal.

gutters-that-leak On average, basic foundation repair services range from about $3,500 to $8,000, depending on the extent of the problem and the size of the property. Some homeowners receive a pleasant surprise after an assessment reveals that an extensive repair job is not necessary.

Some homes may simply need preventive maintenance, which could cost between $500 and $3,000. Any company inspecting your foundation should offer a free estimate as well as a warranty for any work performed.

Foundation Issues by Austin Neighborhood: What We See in the Field

Austin is not one soil profile. Where your home sits, when it was built and what kind of foundation the builder poured all change what goes wrong and how we fix it. Here is what our technicians see most often across the metro.

East & Southeast: Manor, Del Valle, Elgin, Montopolis, MuellerBlackland clayDeep expansive clay sits directly under mostly slab-on-grade homes, and many subdivisions east of 130 were built fast on freshly graded ground. We see seasonal heave at the center of the slab, edge settlement after a dry August, and diagonal cracks at door corners that open and close with the seasons. Typical fix: Cable Lock ST Plus perimeter piers, root barriers and a watering plan. Pflugerville homeowners, see your page.
Central Austin: Hyde Park, Travis Heights, Tarrytown, Clarksville, Bouldin, Allandale, CrestviewPier and beamHousing stock from the 1920s through 1960s, much of it pier and beam, built before modern drainage standards and remodeled several times since. We see sagging or bouncy floors from rotted or undersized beams, moisture in poorly ventilated crawl spaces, and settling under second-story additions. Typical fix: SafeAdjust columns, beam and sill replacement, crawl space drainage and encapsulation, LumberKote on exposed wood.
West & Hill Country: West Lake Hills, Rollingwood, Lakeway, Bee Cave, Steiner Ranch, Dripping Springs, Lago Vista, Marble FallsLimestone shelfThin caliche and clay pockets over fractured limestone on sloped, terraced, cut-and-fill lots. Heave is rare here; differential support and drainage are the issues. We see settlement on the fill side while the rock side holds, water running downhill into the foundation, and retaining wall movement affecting slabs and patios. Typical fix: piers seated on rock where reachable, surface and French drains, regrading, concrete leveling.
North Suburbs: Round Rock, Cedar Park, Leander, Georgetown, Hutto, Liberty Hill, Brushy Creek, Anderson Mill, JollyvilleProduction slabsThe 1990s-and-newer corridor. Production-built slabs, many post-tension, on clay that was moved and compacted during development. We see corner and edge settlement on slabs 15 to 30 years old, brick veneer cracks at garage corners, and doors that stick every late summer. Typical fix: perimeter piers, drainage correction, polyurethane void fill under the slab where needed. Georgetown homeowners, see your page.
South Austin & Hays County: Oak Hill, Shady Hollow, Manchaca, Buda, Kyle, Circle C, Sunset ValleyMixed soilsSouth Austin straddles the escarpment, so soil can change street to street. Homes on clay pockets move; homes on the limestone shelf stay put but drain poorly. We see uneven movement between the front and back of the same house, cracks near mature live oaks and cedar elms, and localized heave from under-slab plumbing leaks. Typical fix: hydrostatic plumbing test first, then piers, root barriers and drainage correction.

Selecting the Right Foundation Contractor for Your Austin, TX Home

Olshan-CST To help ensure you find a qualified contractor, consider the following.

Search for contractors with at least 10 years of industry experience in Austin. Some companies determine “years in business” by adding up the number of years each of their employees has worked. Check with the Better Business Bureau or Best Picks Report or Yellow Pages to validate the company’s advertised years in business.

Make sure the contractor you select is fully insured and licensed. Check to see if the company is financially stable to ensure they will be able to stand by their warranty.

Since foundation repair is a complex procedure that affects your entire home, make sure the contractor you choose has the technical aptitude to adapt repairs to the unique build of your structure. A one-size-fits-all approach wont always cut it. You also want to determine if the contractor has access to all of the latest equipment used to repair foundations. Access to a comprehensive selection of tools, equipment and know-how means they will be able to find the best possible solution to your problem.

Five questions to ask every contractor: Who pulls the permit? How deep do your piers go and how do you know? What exactly does the warranty cover and does it transfer? Will you give me before and after elevation readings? What happens if the house moves again?

Austin Foundation Repair Questions We Hear Every Week

Does homeowners insurance cover foundation repair in Texas?
Usually not. Most Texas policies exclude damage caused by soil movement, settling and drought. Coverage is more likely when the damage is caused by a sudden plumbing leak under the slab, which is why we recommend hydrostatic testing when a leak is suspected. Check your policy language and talk to your agent before assuming either way.
Do I have to repair my foundation before selling a house in Austin?
No law requires repair before a sale, but Texas requires sellers to disclose known foundation problems and prior repairs on the Seller’s Disclosure Notice. Buyers and their inspectors will find movement anyway. A completed repair with a transferable warranty typically makes the home easier to sell and protects your price.
How long does foundation repair take?
Most residential pier jobs in the Austin area are finished in one to three days. Larger homes, interior piers that require tunneling, or jobs that include drainage and plumbing work can take a week or more. Your technician gives you a schedule in writing before work starts.
Do I need a permit for foundation repair in Austin?
Many Central Texas jurisdictions, including the City of Austin, require a permit for structural foundation work. Requirements vary by city and county. Ask any contractor who is responsible for pulling the permit and scheduling inspections before you sign.
Can you repair a post-tension slab?
Yes. Post-tension slabs are common in Austin subdivisions built since the 1990s. They can be lifted and supported with piers, but the cables inside the slab must be located and avoided. Our technicians identify post-tension construction during the assessment and plan pier placement accordingly.
Will my foundation move again after piers are installed?
Piers are driven below the active clay layer to stable strata, so the piered portion of the foundation is supported independently of surface soil moisture. The unpiered interior can still respond to moisture changes, which is why drainage correction, root barriers and consistent watering are part of a complete repair plan. Our Available Lifetime Warranty covers adjustment of the piers we install.
Should I water my foundation during an Austin summer?
If your home sits on clay soil, yes. Consistent moisture around the perimeter keeps the soil from shrinking away from the slab in July and August. A soaker hose 12 to 18 inches from the foundation, run on a schedule, is the standard approach. Your technician can tell you whether your lot is clay or rock.
What is the difference between concrete piers, steel piers and Cable Lock ST Plus?
Pressed concrete piers are economical but can shift on their joints. Steel piers drive deeper but cost more. Cable Lock ST Plus threads a steel cable through concrete cylinders and locks them under tension, combining the mass of concrete with the strength of steel. It is patented and installed only by Olshan.
How much does a foundation inspection cost in Austin?
At Olshan it is free and comes with no obligation. A Certified Structural Technician performs an elevation survey, reviews drainage and trees, and gives you written findings. If you want an independent opinion, a licensed structural engineer typically charges a fee for a written report.

“Overall, simply a great overall experience given the bummer it is when your home needs foundation repair.

All started with Sara’s open communication and patience in explaining all the details and answering my many questions when she came to check our place out when we started seeing those dreaded horizontal cracks in our walls.

Continued with Daniel and his crew as they came to do the hard work. He was kind and professional. The crew was amazingly hard-working. And it was fun to hear them laughing and singing a bit while they dug holes around our house. Just gave me a good feeling to know their work was being done with good spirits and not begrudgingly. Daniel communicated well, too. Answered my questions. Addressed my concerns. And made sure the work was done right and the crew took care of our property.

Heather was very responsive to my questions regarding financing the work. A great communicator as well.

I’m sure I’m missing a few folks. My bad!

All in all, Olshan made a stressful situation a little easier with their professionalism, communication and dedication to their craft.

I can’t recommend them enough.”
