The Honest Truth About Foundation Piers
When your foundation needs repair, the first question is usually "how much will it cost?" But the more important question is "what type of pier do I need?" The wrong pier type can waste your money, fail to solve the problem, or even cause new issues.
At IFR Foundation Repair, we install all three major pier types — concrete pressed piers, steel piers, and helical piers. We don't push one type because it's more profitable. We recommend the right type for your specific soil conditions and structural needs. Here's an honest comparison based on 25+ years of installing piers in DFW clay soil.

Concrete Pressed Piers
Concrete pressed piers are the most common foundation repair method in DFW — and for good reason. They're cost-effective, proven, and work well in many North Texas clay soil conditions.
✅ Pros
- • Most cost-effective option
- • Proven track record in DFW
- • Fast installation (typically 1 day)
- • Concrete is durable and corrosion-resistant
- • Works well for standard slab foundations
⚠️ Cons
- • Limited depth (8-15 feet typically)
- • May not reach below active clay zone in all areas
- • Relies on skin friction for support
- • Can be affected by very deep clay deposits
Concrete pressed piers are installed by driving precast concrete cylinders into the ground using hydraulic pressure. The cylinders are pressed down until they reach load-bearing strata — soil firm enough to support the weight of your home. The friction between the soil and the concrete cylinders provides the driving force and, once installed, the support.
Best for: Standard single-family homes in DFW with moderate foundation movement where the load-bearing strata is within 8-15 feet of the surface.
Steel Piers
Steel piers (also called steel push piers or steel resistance piers) are the premium option — they reach deeper, penetrate below the active clay zone, and provide the most stable long-term support.
✅ Pros
- • Deepest reach (20-30+ feet)
- • Penetrates below active clay zone
- • Reduced skin friction allows deeper installation
- • Best for heavier structures and severe settlement
- • Less affected by shallow soil conditions
- • Provides the most stable, long-term support
⚠️ Cons
- • Higher cost per pier
- • Steel can corrode over decades (slow process)
- • May be overkill for minor settlement issues
- • Requires specialized equipment
Steel piers use high-strength steel sections that are hydraulically pushed into the ground. The reduced skin friction of steel (compared to wider concrete cylinders) allows them to reach much deeper — often 20 to 30+ feet in DFW. This means they penetrate well below the active clay zone (the upper 5-15 feet that shrinks and swells) into stable, load-bearing strata like limestone or firm shale.
Best for: Homes with severe settlement, heavier structures (two-story, brick, commercial buildings), properties where load-bearing soil is deeper, and situations where maximum long-term stability is the priority.
Helical Piers
Helical piers (also called helical piles or screw piles) are steel shafts with helical-shaped bearing plates that are literally screwed into the ground — like a giant screw going into wood.
✅ Pros
- • Minimal vibration during installation
- • Installation depth verified by torque measurement
- • Excellent for lighter structures
- • Ideal for pier and beam foundations
- • Works well in tight access areas
- • Can be installed in unstable or saturated soils
⚠️ Cons
- • May not reach as deep as steel push piers
- • Depth limited by soil resistance and equipment
- • Requires geotechnical report for proper design
- • Cost between concrete and steel piers
Helical piers are installed by applying rotational force — the helical plates act like screw threads, pulling the pier into the ground. The installer monitors torque resistance, which indicates when the pier has reached load-bearing soil. This gives verifiable proof of capacity at the time of installation — something concrete and steel push piers can't always provide.
Best for: Pier and beam foundations, lighter structures, areas with tight access where heavy hydraulic equipment can't reach, and situations where minimal vibration is important (near sensitive structures or utilities).
How to Choose the Right Pier Type
The ASCE Texas Section guidelines emphasize that remedial measures should be cost-effective, practical, and consider the client's needs. Here's how the decision gets made:
1. Soil Conditions
What type of clay soil do you have? How deep is the load-bearing strata? Is there a shallow rock layer? Soil conditions vary significantly across DFW neighborhoods. A free IFR inspection assesses your specific soil type and depth to stable strata.
2. Foundation Type
Slab-on-grade foundations typically use concrete or steel push piers. Pier and beam foundations often use helical piers or a combination. Commercial foundations may require steel piers for higher load capacity.
3. Severity of Movement
Minor settlement may only need concrete piers. Severe settlement or deep clay issues may require steel piers to reach below the active zone. The ASCE Texas Section evaluation criteria (deflection L/360, tilt 1%) help determine severity.
4. Budget vs. Long-Term Value
Concrete piers are most cost-effective. Steel piers cost more but provide the deepest, most stable support. The ASCE guidelines note that remedial measures should be cost-effective — but "cost-effective" includes considering long-term performance, not just upfront cost.
5. Engineer's Recommendation
For complex cases, the ASCE Texas Section guidelines recommend a Level B or C investigation by a licensed Texas Professional Engineer. The engineer's report specifies the repair method, number of piers, and placement — then IFR executes the engineer-designed repair.

Frequently Asked Questions
What is the difference between concrete piers and steel piers?
Concrete pressed piers use hydraulic pressure to drive concrete cylinders into load-bearing strata. They're cost-effective and work well in many DFW clay soil conditions. Steel piers use high-strength steel that can reach deeper, more stable strata below the active clay layer. Both are recognized by ASCE Texas Section guidelines. Steel piers typically reach 20-30+ feet; concrete piers typically reach 8-15 feet.
Which type of foundation pier is best for Texas clay soil?
There is no single best pier type. The right choice depends on soil conditions, depth of stable strata, structure weight, and budget. Concrete piers are cost-effective for many homes. Steel piers are better for deeper issues or heavier structures. Helical piers work for lighter structures. ASCE Texas Section guidelines recognize all three. A professional inspection determines the best option.
How much do concrete piers cost compared to steel piers in DFW?
Concrete piers generally cost $350-$700 per pier; steel piers typically $700-$1,400 per pier. Most homes need 8-15 piers, so total costs range from $3,500 to $15,000+. IFR offers free inspections and same-day estimates with no obligation.
How deep do foundation piers go in DFW clay soil?
Concrete piers typically reach 8-15 feet. Steel piers can reach 20-30+ feet, penetrating below the active clay zone. Helical piers typically reach 10-25 feet depending on torque resistance. The active clay zone in DFW is usually the upper 5-15 feet. Piers below this zone provide more stable long-term support.
What are helical piers and when are they used?
Helical piers are steel shafts with helical-shaped bearing plates screwed into the ground using hydraulic equipment. They're useful for lighter structures, pier and beam foundations, tight access areas, and situations requiring minimal vibration. ASCE Texas Section guidelines recognize them as a valid remedial measure.
Can foundation piers fail after installation in clay soil?
Yes, piers can fail if installed incorrectly, if they don't reach stable strata, or if site conditions change from plumbing leaks or drainage problems. ASCE Texas Section guidelines note perfection is not attainable. Choosing an experienced contractor with a lifetime transferable warranty is critical. IFR has been installing piers in DFW since 2000.
Does IFR Foundation Repair use all three types of piers?
Yes. IFR installs concrete pressed piers, steel piers, and helical piers, plus pier and beam repair and drainage solutions. Our free inspection determines the best method for your specific conditions. All work follows ASCE Texas Section guidelines.
How long does pier installation take?
Most residential pier installations are completed in a single day, regardless of pier type. After installation, ASCE Texas Section guidelines recommend floor elevation measurements and testing water supply and drain lines for leaks if jacking or lifting was involved.
What is the warranty on foundation piers?
IFR offers a lifetime transferable warranty on all pier work. The warranty stays with the home, not the homeowner. Contact IFR to transfer during property sales. Plumbing leaks or poor drainage can void coverage. ASCE does not issue warranty recommendations — warranties come from the contractor.
How do I know which pier type my foundation needs?
A professional inspection is the only way to determine the right pier type. IFR's free inspection assesses soil conditions, foundation type, depth of stable strata, structure weight, and severity of movement. This aligns with a Level A investigation per ASCE Texas Section guidelines. For complex cases, we recommend a licensed Texas Professional Engineer for a Level B or C investigation.
