Underpinning brackets provide a secure connection between existing foundations and helical piles, transferring structural loads to stable bearing soils. They are designed to stabilize or lift settled foundations in residential, commercial, and industrial applications.
Types of Underpinning Brackets
Standard Duty Utility
The Standard Duty Utility bracket is the most widely used configuration for residential and light commercial foundation repair. It is designed to support conventional concrete footings while transferring structural loads efficiently to the helical pile. This bracket provides a balance between strength, installation efficiency, and versatility, making it suitable for most underpinning applications where sufficient excavation space is available.
Typical applications include residential foundation stabilization, basement wall support, garage and porch foundations, and settlement remediation of light commercial buildings.
- Designed for installation beneath existing concrete footings
- Compatible with common square-shaft and round-shaft helical piles
- Suitable for lifting or permanently stabilizing settled structures
- Engineered for moderate to high structural loads
Low Profile Utility
The Low Profile Utility bracket is intended for projects where excavation depth or working space is limited. Its compact geometry allows installation beneath shallow foundations or within confined areas such as crawl spaces without requiring extensive excavation. Although its structural capacity is generally lower than larger bracket designs, it provides an effective solution where accessibility is the primary constraint.
Typical applications include crawlspaces, shallow strip footings, structures with limited excavation clearance, and foundation repairs near property boundaries.
- Compact design requiring less excavation
- Easier installation in restricted work areas
- Suitable for light to moderate structural loads
- Compatible with selected helical pile systems
Large Utility
The Large Utility bracket is designed for applications involving higher structural loads or larger foundation elements. Its reinforced construction and increased bearing surface enable it to support heavier buildings and commercial structures while accommodating larger helical pile shafts. This bracket is commonly selected where greater load transfer capacity is required.
Typical applications include commercial buildings, industrial facilities, heavy masonry structures, mutli-story buildings, and large foundation elements.
- Reinforced steel construction for increased strength
- Larger bearing area for improved load distribution
- Compatible with larger helical pile shaft sizes
- Intended for high-capacity underpinning applications
