What Are Helical Piers and Why Are They So Effective?
Helical piers are steel foundation anchors with spiral plates that are mechanically screwed deep into the ground until they reach stable soil. This creates a strong, long-lasting foundation that resists settling, shifting, and frost movement.
Unlike traditional concrete footings, helical piers install quickly, require minimal digging, and can support weight immediately—making them a reliable solution for many construction projects.
Helical piers are commonly used for:
• Deck foundations
• Porches and patios
• Home additions
• Garages and sheds
• Retaining walls
• Foundation repair and stabilization
Because they extend below the frost line, helical piers help prevent movement caused by Minnesota’s freeze–thaw cycles.
At TR Construction & Outdoor Services, we use helical piers to build stronger, more stable foundations that last for years.
