Understanding Foundation Lifting: Is This the Right Solution for Your Home?
Foundation lifting is a specialized repair technique used to raise a settled or sunken foundation back to its original, level position. This process, which uses methods like steel pier installation or polyurethane foam injection, restores your home’s structural stability and prevents further damage. If you see cracked brick, uneven floors, or sticking doors, your foundation may have settled.
Quick Answer: What You Need to Know About Foundation Lifting Services
- What it is: A process that lifts settled foundations using piers or foam to restore a level state.
- Cost range: $4,500 to $38,000+, depending on the severity and method.
- Common methods: Steel pier installation ($1,000-$3,000 per pier) or polyurethane foam injection ($1,000-$3,000 per injection).
- Timeline: Single-day foam repairs to week-long pier installations.
- Best for: Differential settlement, severe sinking, or homes requiring flood protection.
Foundation settlement occurs when the soil beneath your home shifts, compresses, or erodes, causing part of the foundation to sink. In the Texas Hill Country, this is often caused by expansive clay soils that swell when wet and shrink when dry. When this settlement is uneven—a condition called differential settlement—it creates stress throughout your home, leading to wall cracks, sloping floors, and jammed doors. Total Foundation & Roofing provides expert foundation repair solutions designed to address these exact issues.
Foundation lifting corrects this by physically raising the settled portion of your foundation, transferring your home’s weight onto stable soil or a reinforced base. However, not every crack requires this level of intervention. Minor issues may be resolved with crack repair services or drainage improvements. An accurate diagnosis from a qualified professional is essential.

With over 18 years of experience in the Texas Hill Country, my team has restored hundreds of foundations in communities like Kerrville, TX, giving homeowners lasting peace of mind. This guide will explain when lifting is necessary, the methods available, and how to choose the right solution for your home.
What is Foundation Lifting and Why is it Necessary?
When you see sloping floors or zigzagging wall cracks, you are witnessing foundation settlement. Foundation lifting is the definitive repair process that returns a sunken foundation to its original level, restoring structural integrity and preventing further damage. It addresses the root cause of settlement—unstable soil—by transferring your home’s weight onto deeper, more stable ground or by reinforcing the soil directly beneath it.
Without this intervention, minor issues can escalate into a major structural crisis that threatens your home’s safety and value. Total Foundation & Roofing provides expert foundation repair solutions designed for the unique soil challenges in the Texas Hill Country, ensuring a permanent solution that protects your investment.
Telltale Signs Your Foundation Needs Lifting
Your home communicates distress through clear warning signs. Ignoring them can lead to more extensive and costly repairs.
- Large diagonal or stair-step cracks in drywall or exterior brick are a classic indicator of foundation movement. These often appear near the corners of doors and windows.
- Doors and windows that stick or fail to close properly indicate your home’s frame has been twisted out of alignment by a shifting foundation.
- Uneven or sloping floors are a direct result of differential settlement, where one part of your foundation has dropped below the rest.
- A tilting chimney that leans away from the house signals serious, localized settlement.
- Gaps forming around window frames, door frames, or between the wall and ceiling show that the structure is being pulled apart.
- Sagging or bouncy floors in homes with pier and beam foundations suggest the support system has failed.
Addressing these signs early with a professional inspection can prevent the need for more extensive crack repair services later.
5 Key Warning Signs to Watch For:
- Diagonal or stair-step cracks in walls
- Doors and windows that stick or don’t close
- Uneven, sloping, or bouncy floors
- Visible gaps between walls and ceilings or floors
- A chimney that leans or pulls away from the house
Common Causes of Foundation Settlement in Texas
Understanding the causes of settlement in the Texas Hill Country can help you identify risks to your property.
- Expansive Clay Soil: This is the primary cause in our region. The soil swells dramatically with moisture and shrinks when dry, creating a constant cycle of movement that stresses and shifts your foundation.
- Poor Drainage: Water pooling near your foundation saturates the soil unevenly, leading to differential settlement. Clogged gutters and improper grading are common culprits.
- Soil Erosion: Heavy rains can wash away soil from beneath your foundation, creating voids and leaving it unsupported.
- Plumbing Leaks: Undetected leaks under your slab can create soft spots in the soil, causing localized settlement.
- Tree Roots: Large tree roots can draw moisture from the soil, causing it to shrink, or grow directly under the slab, exerting upward pressure.
- Extreme Weather: Prolonged droughts and torrential rains, common in Texas, cause drastic changes in soil moisture and volume. Proper water management is critical, as highlighted in FEMA guidelines on mitigating flood risks.
These local challenges make professional expertise crucial for homeowners in areas like Kerrville, TX.
A Homeowner’s Guide to the Foundation Lifting Process
Foundation lifting is a technical repair that restores your home’s elevation and structural stability. The process involves carefully raising the settled portions of your foundation and transferring the structure’s weight onto a solid support system, providing a permanent solution to settlement issues.
The specific approach depends on your foundation type, the severity of settlement, and local soil conditions. A professional assessment is necessary to determine the best strategy, as a home with minor settlement requires a different plan than one that has dropped several inches. Our house leveling services are customized to address each home’s unique situation.
Exploring Foundation Lifting Methods: Piers vs. Foam
Two primary methods are used for foundation lifting: foundation piers and polyurethane foam injection. Each is suited for different scenarios.
Foundation Piers: The Deep-Support Solution
Also known as underpinning, this method involves driving steel piers deep into the ground to reach stable, load-bearing soil or bedrock. Hydraulic jacks then lift the foundation, which is secured to the piers. The two main types are push piers, driven by the house’s weight, and helical piers, which are screwed into the ground. Piering is ideal for severe settlement and heavy structures. It is an invasive process requiring excavation and typically costs $1,000 to $3,000 per pier, with most homes needing 8 to 15 piers.
Polyurethane Foam Injection: The Modern, Less Invasive Approach
Often called poly-lifting, this method involves injecting high-density polyurethane foam through small, penny-sized holes in the slab. The foam expands to fill voids, compact loose soil, and lift the concrete. This process is fast, minimally disruptive, and can often be completed in a single day. The foam also helps stabilize the surrounding soil to prevent future sinking. It is best for moderate settlement of concrete slabs and generally costs $1,000 to $3,000 per injection point.
The Unified Jacking System: Precision Lifting Technology
For complex projects, a Unified Jacking System (UJS) provides unparalleled control. This computerized hydraulic system synchronizes multiple jacks to lift the entire structure in precise, tiny increments, minimizing stress and reducing the risk of damage during the lift. It is especially valuable for large or historic homes.
Comparing Your Options: Which Method is Right for You?
| Feature | Foundation Piers | Polyurethane Foam Injection |
|---|---|---|
| Cost | $1,000-$3,000 per pier (higher total) | $1,000-$3,000 per injection (often lower total) |
| Invasiveness | High (excavation required) | Low (small drill holes) |
| Timeline | One week or more | Usually one day |
| Best For | Severe settlement, heavy structures | Moderate settlement, concrete slabs |
| Landscaping Impact | Significant | Minimal |
| Permanence | Permanent, anchored to deep soil | Long-lasting, stabilizes existing soil |
Understanding the Cost of Foundation Lifting
The cost of foundation lifting can range from $4,500 to over $38,000. The final price depends on several factors:
- Severity and Complexity: Widespread, differential settlement costs more than minor, localized sinking.
- Foundation Type: Slab, pier and beam, and basement foundations require different techniques.
- Home Size and Weight: Larger, heavier homes need more support points.
- Chosen Method: Piering is often more expensive than foam injection.
- Site Accessibility: Difficult access can increase labor costs.
- Additional Repairs: Costs may include fixing plumbing leaks or improving drainage.
It is wise to check your homeowner’s insurance policy, but damage from gradual settlement is typically not covered. For an accurate estimate, schedule a professional inspection by calling us at (830) 257-4111.
When to Choose Lifting Over Other Repairs
While some issues can be addressed with other foundation repair services, lifting is the correct choice in specific situations.
- Significant or Differential Settlement: When one part of your house has dropped noticeably lower than the rest, only lifting can correct the elevation and restore structural balance.
- Severe Sinking: If your foundation has dropped several inches, lifting is necessary to prevent structural failure.
- Flood Mitigation: Raising a home above the base flood elevation protects it from water damage and can lower insurance premiums.
- Creating New Space: Lifting can allow for the creation of a new basement or a higher crawl space.
- Unstable Soil Conditions: When soil is consistently weak, deep piers provide a permanent solution by transferring the load to stable strata.
Lifting is the only method that corrects the root cause of an unlevel foundation, rather than just addressing the symptoms.
