Engineered Stability for Retaining Walls & Landscaping Structures
Retaining walls and landscaping features don’t just shape your yard—they protect it. Whether you’re reinforcing a slope, building garden terraces, or anchoring a hillside staircase, your project needs a foundation that stands the test of time. At Screw Pile Installers, we specialize in helical pile foundations for residential retaining walls and outdoor structures across British Columbia and Alberta—offering unmatched stability, strength, and longevity in every soil type.
Helical piles provide a cleaner, faster, and more precise alternative to concrete footings—perfect for tie-ins to existing homes where space, soil, or access can be challenging.
Screw Pile Foundations for Retaining Walls
Traditional retaining walls often rely on poured concrete or shallow footings that can shift, crack, or fail over time due to soil movement or frost heaving. Helical piles solve these issues with deep, torque-driven anchoring that locks into stable ground below the frost line—ensuring long-term structural integrity and preventing wall failure.
Whether you’re a homeowner, landscaper, or contractor, our piles provide lasting performance and a maintenance-free foundation for any landscape design.
WHY CHOOSE US
Why Choose Helical Piles for Retaining Walls
When it comes to retaining walls, strength starts below the surface—and that’s exactly where Screw Pile Installers excels.
Superior Soil Stability
Screw piles transfer load deep into stable ground, preventing wall tilting, bulging, or sliding caused by soil pressure.
Frost-Proof Anchoring
Installed below frost depth, our galvanized piles eliminate movement from freeze-thaw cycles.
Precise Installation
Torque-monitored installation ensures each pile achieves the exact load-bearing requirement for your design.
Minimal Site Impact
Compact equipment means easy access for backyards, gardens, and tight residential areas—without damaging existing landscaping.
Long-Term Durability
Hot-dip galvanized steel piles are corrosion-resistant and built to last 75 + years, even in moist or clay-rich soils.
Let’s Build a Strong Foundation Together
No waiting for concrete to cure, foundations are ready the same day, saving valuable build time.
Our process ensures precision, performance, and peace of mind for every retaining wall or landscaping foundation project.
[01]
Site Assessment & Design Review
We begin with a detailed site visit to evaluate slope conditions, soil type, and load requirements.
[03]
Layout & Marking
Each pile location is carefully marked to align with wall footings or structural anchor points—ensuring optimal support and spacing.
[05]
Bracket or Beam Attachment
Helical piles are fitted with structural brackets or tie-back connections to anchor the wall or structure securely.
[02]
Pile Installation
Using specialized hydraulic drive equipment, our certified technicians install each helical pile to the engineered torque depth, achieving verified load capacity immediately.
[04]
Load Testing & Verification
We perform on-site torque verification and, if required, full load testing to confirm each pile’s strength.
[06]
Final Inspection & Cleanup
Our team completes a full inspection to verify all engineering standards are met. The site is left clean, level, and ready for backfilling or finishing.
Comparison
Helical Piles vs. Conventional Retaining Wall Footings
Yes. Helical piles are suitable for timber, stone, block, or concrete retaining walls—offering deep anchoring and long-term lateral resistance.
Even smaller retaining walls benefit from screw piles, especially on slopes or poor soil. They prevent movement and extend the lifespan of your wall.
Yes. We can retrofit screw piles behind or below existing walls to provide additional support and stop further movement.
Yes. Installation requires minimal excavation and produces no concrete waste—making it a low-impact choice for landscaping projects.
Pricing depends on wall size, soil type, and load requirements. Most residential retaining wall applications range from $200 – $400 per pile installed, including engineering verification and load testing.
