Shoring and Underpinning | SJ Hauck Construction

Trust in the East Coast’s premier structural support, relocation, and demolition experts. Serving nationwide with deep understanding of unique geological and structural challenges, from the clay-heavy soils and high water tables of the lakefronts to the dense urban constraints of Manhattan and Philadelphia.

Renovating a large commercial property involves complex safety considerations. Neighboring buildings often require stabilization, or foundations may need to be reinforced to reach the depth of a new construction site. Whether your project calls for relocating structural members, adding openings to load-bearing walls, or remediating corroded supports that have begun to buckle, our comprehensive shoring and underpinning solutions ensure a seamless and safe project delivery.

The shoring systems consist of bright orange vertical main posts topped with adjustable silver screw jacks, which extend upwards to support heavy horizontal steel I-beams running directly beneath the exposed wooden ceiling joists. The system is braced together with silver metallic scaffolding tubes and couplers, and the entire assembly rests on thick steel or wooden sill beams on the floor to distribute the massive load. Temporary string lights illuminate the dim, open workspace.

Underpinning & Shoring Support Services

Specialized Equipment

Our capability to conquer the most complex leveling and support projects is backed by an advanced fleet of heavy-duty machinery:

High-Pressure Hydraulic Jacks

We utilize jacks with capacities ranging from standard units to specialty systems capable of lifting up to 1,000 tons.

Unified Jacking Systems

For projects requiring absolute precision, our unified jacking machines use synchronous technology to raise or lower multiple points at the exact same rate. This prevents structural stress or cracking by ensuring the load remains perfectly level, regardless of weight distribution.

Precision Load Points

Our systems use high-yield cylinder pads and custom grillage to ensure even load distribution across all support points, protecting the existing structural fabric from localized distortion.

Frequently Asked Questions About Shoring & Underpinning

What is the relationship between Support of Excavation (SOE) and shoring?

While often used interchangeably, “support of excavation” (SOE) is the comprehensive engineering term for systems designed to protect the sides of a cut. Shoring is a primary component of SOE, acting as the temporary “muscle” that prevents soil movement to ensure the safety of workers and the integrity of adjacent roadways or utilities. Common SOE techniques include soldier pile and lagging, secant walls, and sheet piling.

The main distinction lies in the duration and objective of the support. Shoring provides temporary stability for soil and nearby structures during active excavation or renovation to prevent collapses while work is in progress. Underpinning is a permanent structural modification that strengthens or extends an existing foundation, transferring the building’s weight to deeper, more stable soil to ensure long-term stability.

Geology plays a critical role in system selection. The region features clay-heavy soils and high water tables that necessitate specialized water-tight solutions like secant pile walls or shotcrete application. In contrast, the sandy soils of coastal Delaware or southern New Jersey often require deep foundation systems like helical piles to reach competent bearing strata.

Underpinning is typically required when a foundation shows signs of distress, such as settling cracks or uneven floors, or when the building’s load-bearing requirements change. Common triggers include adding additional stories to a building, installing heavy industrial machinery, or lowering a basement floor to increase usable square footage.

Yes. Local building codes, such as the NYC Administrative Code and the New Jersey Uniform Construction Code, mandate that any excavation deeper than an adjacent foundation must be supported by underpinning or shoring to protect neighboring property. These designs often require a professional engineer’s (PE) seal and regular monitoring to ensure compliance with safety regulations.
