A geotechnical investigation is essential because it provides the foundational data required to design a safe and reliable helical pier system. Soil properties vary significantly, and understanding the specific conditions at your site—such as soil stratigraphy, groundwater levels, and the presence of expansive clay—directly influences foundation stability. Key reasons for…

Stabilizing a 100-year-old foundation requires a specialized approach that balances modern engineering with the preservation of historic materials. We utilize several proven methods to address the unique challenges of aging masonry and expansive soil conditions. Because every historic property is unique, a custom site inspection is required to determine the…

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…
