What Is Push Pier Foundation Repair?
Push pier foundation repair is a structural stabilization method designed to lift and secure settling foundations. The system involves driving heavy-duty steel piers deep into the ground until they reach stable, load-bearing strata. Once anchored, hydraulic jacks are used to lift the foundation back to its original elevation or as close as possible. The piers remain in place permanently, providing ongoing support.
This method is highly effective for homes and commercial buildings suffering from foundation settlement due to soil movement, erosion, or poor construction. Push piers are especially well-suited for structures with heavy loads or where minimal disruption to the property is preferred.
How Push Pier Systems Work
1. Foundation Assessment
Every project begins with a thorough inspection. Our trained technicians evaluate your foundation, measure the extent of settlement, and determine whether push piers are the best solution.
2. Pier Installation
We excavate small sections near the foundation footing, install steel foundation brackets, and drive the push piers hydraulically into the earth until they reach competent soil or bedrock.
3. Lifting and Stabilizing
Once all piers are installed, synchronized hydraulic jacks gently lift the structure. The process is carefully monitored to prevent over-lifting or additional damage.
4. Permanent Support
After lifting, the system is locked into place, and the excavated areas are backfilled. The piers will continue to provide support indefinitely.
Benefits of Push Pier Foundation Repair
- Permanent Stabilization: Once installed, push piers provide continuous structural support, protecting against future settlement.
- End-Bearing Support: Push piers are end-bearing, meaning they do not rely on friction for capacity. This ensures greater stability and effectiveness in a wider range of soil conditions.
- Load-Tested for Accuracy: Each pier is load tested during installation to verify that it can support the required weight, ensuring a reliable and customized repair.
- Deeper Installations Possible: The system uses a starter tube with a friction collar, allowing it to reach greater depths to find competent, load-bearing strata.
- Durable Construction: Made from high-strength steel pier sections with sleeved couplings, these piers offer exceptional resistance to bending and deformation.
- Corrosion Resistant: Push piers have a long lifespan with resistance to corrosion, with a design life exceeding 100 years in moderate soil conditions.
- Optional Galvanized Coating: For added protection, push piers are available with a hot-dipped galvanized coating to further guard against corrosion.
- Minimal Disruption: Installation is performed with small excavation points, minimizing damage to landscaping or property features.
- Year-Round Installation: Push piers can be installed in nearly any weather, making them an ideal solution for urgent repair needs.
- Compatible with Multiple Structures: Ideal for residential homes, commercial buildings, and older structures with brick or stone foundations.
- Fast and Efficient: The process is often completed in days, not weeks, with immediate results.
