Screw Pile Foundation System: The Modern Building Solution

A screw pile foundation system offers a revolutionary approach to structural support, combining engineering precision with installation efficiency. Unlike traditional concrete foundations, these steel pile systems provide immediate load capacity, year-round installation capability, and exceptional longevity. At Down Force Piling, we specialize in designing and installing screw pile foundations tailored to Calgary's unique soil conditions and climate challenges.

What Is a Screw Pile Foundation System?

A screw pile foundation system consists of:

• High-strength steel shafts (typically 2⅞" to 4½" diameter)

• Helical bearing plates (8" to 16" diameter)

• Corrosion-resistant coatings (hot-dip galvanized)

These components work together to:

• Transfer structural loads to stable soil strata

• Resist frost heave and seismic forces

• Provide adjustable elevation control

Key Benefits of Screw Pile Foundations

1. Superior Engineering Performance

• 50+ year design life (ASTM A123 galvanized steel)

• 150% load-test verified capacity

• Below-frost-line installation (6-8 feet in Calgary)

2. Economic Advantages

• 30-50% faster installation than concrete

• 20-40% cost savings on average projects

• Minimal site restoration required

3. Environmental Benefits

• No concrete curing waste

• Low carbon footprint installation

• Fully recyclable materials
