For historical home renovations, the most effective method for foundation stabilization is steel piering. This approach is specifically designed to handle heavy masonry and historic finishes while addressing the challenges of expansive clay soils common in the Littleton area.

We recommend this method for historical structures due to several key factors:

• Permanent Load Transfer: Galvanized steel piers are driven through unstable surface soil until they reach bedrock or competent load-bearing strata. This transfers the entire weight of the building to stable earth, permanently halting settlement.
• Immediate Stability: Unlike concrete underpinning, which requires time to cure, steel piers are immediate-load capable. This means the structure is stabilized the moment the piers are installed, which is critical for preventing further stress on delicate historic framing.
• Minimal Site Disruption: We use small, isolated access pits (typically 2×2 feet) that can be dug by hand or light equipment. This precision preserves original stonework, mature landscaping, and patios that are often central to a historic property’s character.
• Vibration-Free Installation: Our certified crews use hydraulic driving or rotary techniques that are quiet and virtually vibration-free, protecting fragile interior finishes and plaster from the damage often caused by heavier construction methods.

While helical piers are also a high-performance option often used for light structural loads or new construction, driven steel piers remain the preferred choice for heavy historical renovations due to their brute driving force and predictable refusal at bedrock.

We recommend consulting a licensed structural engineer to provide a definitive diagnosis and design recommendations tailored to your specific property.
