Quick, low-risk steps
- Hire a Texas-licensed structural engineer for an independent evaluation before contacting contractors.
- Ask each contractor to explain why they recommend a specific method for your home's soil and foundation type.
- Request a detailed scope of work including pier type, quantity, depth, and installation method.
- Compare proposals side-by-side using a foundation quote comparer tool.
- Verify that the chosen method has a track record in your local soil conditions.
Common Foundation Repair Methods
Several piering methods are used to stabilize and lift residential foundations. The right choice depends on your home's foundation type, the underlying soil, and the extent of movement. A structural engineer can help determine which method is appropriate.
No repair method is universally superior. Each has advantages and limitations. Understanding the basics will help you ask better questions when reviewing proposals.
- Concrete pressed pilings: precast concrete cylinders driven into the ground.
- Steel piers: hydraulically driven steel sections that can reach deeper, more stable soil.
- Helical piers: screw-like steel shafts that are turned into the soil, often used for lighter structures or additions.
- Mudjacking or slabjacking: pumping a grout mixture under a slab to fill voids and lift concrete.
- Polyurethane foam injection: injecting expanding foam to lift and stabilize slabs.
How Soil Conditions Affect Method Choice
Dallas–Fort Worth area soils often contain expansive clays that shrink and swell with moisture changes. This movement can cause foundation distress. The USDA provides soil survey information that can help you understand general soil risks in your area.
A local geotechnical engineer or structural engineer can interpret soil data for your specific property. They can recommend a repair method and depth that accounts for the active soil zone.
- Expansive clay soils may require deeper piers to reach stable strata.
- Soil surveys show general conditions but cannot replace a site-specific investigation.
- Ask your engineer how the repair depth was determined.
- Consider drainage improvements to reduce future soil movement.
Evaluating Repair Proposals
When comparing bids, look beyond the total cost. Examine the engineering rationale, pier specifications, and warranty terms. A lower price may mean fewer piers or shallower installations.
Ask each contractor to provide a detailed scope of work. This should include the number and type of piers, target depth, and how they will handle interior and landscape restoration.
- Compare pier type, quantity, and installation depth across proposals.
- Check if the proposal includes a plumbing leak test.
- Ask about permit and inspection requirements.
- Review warranty coverage and transferability.
- Understand what triggers a change order and additional costs.
Questions to Ask Before Choosing a Method
A reputable contractor will welcome your questions. If a contractor pressures you to sign quickly or cannot explain their recommendation, consider it a red flag.
An independent engineer can review proposals and help you understand the technical details. This second opinion can protect you from unnecessary or inadequate repairs.
- Why is this method recommended for my home's soil and foundation type?
- How do you determine the required pier depth and quantity?
- What is the expected lift, and how is it measured?
- What restoration work is included, and what is excluded?
- Can you provide references for similar projects in my area?

Common questions
What homeowners ask next
Which foundation repair method is best?
There is no single best method. The right choice depends on your home's foundation type, soil conditions, and the extent of damage. An independent structural engineer can recommend an appropriate method.
How deep should foundation piers go?
Pier depth depends on the depth of stable, load-bearing soil. In areas with expansive clay, piers often need to extend below the active zone. A geotechnical investigation can determine the required depth.
Do I need a permit for foundation repair?
Many municipalities require a permit for foundation repair. Your contractor should handle permitting, but verify this before work begins. Check with your local building department for specific requirements.
