Yes, helical pier stabilization is an ideal solution for historic foundation restoration. Unlike traditional excavation methods, helical piers—also known as screw piles—are screwed into stable load-bearing soil deep beneath the active movement zone with minimal vibration and disruption to the fragile original masonry.
We utilize systems like Hubbell helical piles to gently lift and support settled sections, effectively transferring the structural load to competent soil without stressing the building’s historic fabric. This method is often preferred for preservation projects because:
- It requires minimal excavation, protecting the surrounding landscaping and original structure.
- The installation process uses a hydraulic drive head that allows for precise torque monitoring, ensuring each pier meets its engineered design capacity.
- It is a reversible method, which aligns with National Park Service preservation standards for maintaining structural integrity while protecting authenticity.
Before proceeding, we conduct a professional site assessment to evaluate crack patterns and soil profiles. Because permitting and inspection requirements vary by jurisdiction in Centennial and the Denver metro area, we recommend working with a design-build team familiar with local historic preservation rules.
