Underpinning Repair: A Comprehensive Guide
Your home’s foundation is the bedrock of your family’s safety and your property’s value. When foundation issues arise, they endanger both. At Groundworks, we’ve helped millions of homeowners restore their homes’ stability through professional underpinning foundation and repair services.
Foundation problems do not improve on their own, and waiting too long can lead to costly repairs. Whether you’re noticing subtle signs of foundation stress or facing significant structural issues, understanding your options for foundation repair is crucial. In this comprehensive guide, we explore what underpinning is, why it might be necessary, and how Groundworks’ proven house underpinning solutions can protect your home for generations to come.
What Is Underpinning for House?
When it comes to protecting your home’s structural integrity, underpinning repair plays a vital role. But what is underpinning? Simply put, it’s a construction technique used to strengthen and stabilize an existing foundation by extending it to more supportive soils or bedrock.
House underpinning becomes necessary when the original foundation is compromised or needs additional support. This can happen due to many factors, including:
- Soil erosion or settlement
- New floor additions
- Nearby excavation
- Foundation damage or deterioration
8 Signs You Need Underpinning Repair
Foundation damage comes in many forms, including:
- Foundation wall cracks
- Floor cracks
- Cracks in drywall
- Doors and windows that stick or won’t close properly
- Sloping or uneven floors
- Separation between the walls and floor or ceiling
- Cracking and tilting chimney
- Foundation settlement or sinking
The Best Underpinning Repair Methods
House underpinning takes many forms. However, they are not created equal.
Some traditional underpinning foundation methods—including concrete underpinning, concrete or steel concentric piers, and square or round shaft helicals—simply cannot withstand the structure’s weight and problematic soils, and ultimately fail over time.
At Groundworks, we care about your safety and creating a stable living environment for your family. We install house underpinning solutions tested and proven to permanently stabilize your home’s foundation. We offer three types of foundation piers for underpinning repair:
1. Helical Piers
Our helical pier system provides exceptional stability for both light and heavy structures. These steel piers feature helical plates that screw into the ground like a giant corkscrew, reaching stable soil layers deep beneath your home. They’re ideal for:
- Lighter structures like porches and additions
- Areas with varying soil conditions
- Projects requiring minimal excavation
- Sites with limited access
2. Push Piers
Push piers, also known as resistance piers, are our go-to solution for heavier structures requiring significant support. These straight steel piers are hydraulically driven into the ground until they reach bedrock or competent soil. Benefits include:
- Maximum stability for heavy structures
- Potential foundation lifting capabilities
- Minimal site disruption
- Fast installation process
- Immediate support after installation
3. Slab Piers
Specifically designed for concrete slab foundations, our slab pier system addresses settlement issues in slab-on-grade homes. These specialized piers:
- Stabilize settling concrete slabs
- Provide an opportunity for slab lifting
- Require minimal interior disruption
- Offer a permanent solution to slab settlement
- Can be installed in tight spaces
The Underpinning Repair Process
Since we install three types of house underpinning, each process looks slightly different. For example, we attach a bracket to the foundation footing to allow for the easy installation of push piers; but this bracket is added after helical piers are placed in the ground.
You can learn more about how each system is installed by visiting the solution pages linked in the previous section.
While individual installations may vary, all our underpinning repair solutions have the same goal: to permanently stabilize your foundation and potentially lift settling sections.
Here is a general overview of the underpinning foundation process:
1. Initial Assessment
- Structural evaluation
- Soil testing
- Foundation inspection
2. Planning Phase
- Underpinning repair method selection
- Design development
- Permit acquisition
3. Implementation
- Site preparation
- Sectional excavation
- Installation of new support
- Quality testing
4. Completion
- Benchmarking
- Site restoration
- Final inspection
- Documentation

Underpinning Repair FAQs
The duration of house underpinning varies based on the project scope, but our efficient crews typically install underpinning repair solutions for residential properties within a few days to a week.
While possible, temporary relocation is often recommended due to noise, dust, and potential safety concerns. Your inspector will review the underpinning repair process based on your home’s needs.
Coverage varies by policy. Some homeowner’s insurance plans cover house underpinning if the damage was caused by covered perils, but many consider it a maintenance issue. Check with your provider for your policy’s specific details.
