Earth Contact Products, the leading underpinning bracket manufacturer in the United States, has a complete line of utility helical brackets. These underpinning brackets are used for strengthening and stabilizing the foundation of an existing building or other structure. The use of underpinning brackets may be necessary for a variety of reasons:
The original foundation is simply not strong or stable enough
The usage or loads of the structure has changed
The properties of the soil supporting the foundation may have changed (possibly through subsidence) or were mischaracterized during design
The construction of nearby structures necessitates the excavation of soil supporting existing foundations
It is more economical, due to land price or otherwise, to work on the present structure's foundation than to build a new one
Underpinning is accomplished by extending the foundation in depth or width so it either rests on a more supportive soil stratum or distributes its load across a greater area. The use of helical anchors and utility brackets is a common method in underpinning.
Helical anchor are screwed into the soil below the active soil layers to create a deep foundation support system. When combined with a utility bracketing system the foundations load is transferred to a new stable load bearing stratum.
Helical pier underpinning has many advantages over other methods of piering, including:
Excellent for light weight structures
Does not require a reaction force to install
No vibration installation
All weather installation
Not effected by high water tables
Installed with light weight portable equipment
All ECP helical brackets are designed to be used in conjunction with our hydraulic manifold lifting system. This manifold lifting system was designed for the precise control and stability required by many engineers for a structural lift. ECP recommends that a registered engineer monitors all structural lifting activities.
ECP Helical Brackets
Our lineup of helical brackets has capacities ranging from 40kips to 98kips. Whether using square bar helicals for residential underpinning or 3-1/2” round shaft helicals for commercial work there is a helical / bracket combination right for your next project.

NOTES:
1. These are mechanical capacity ratings. Foundation strength and soil capacity will dictate actual capacity.
2. Bracket Lift Height Can Easily Be Increased By Ordering Longer Continuously Threaded Bracket Rods.
3. The TAB-LUB Bracket is the same component for three different shaft sizes; the Pile Cap configuration varies to accommodate the appropriate shaft for the application.
