HJ Foundation is equipped to provide you with a cost-effective, fast installation with reduced excavation and dewatering with Tangent Bearing Elements (TBEs), a more practical alternative to CFA piles, ACIP piles, large bored piles, caissons, shafts, and/or barrettes.

Common Uses

  • To support tall, slender buildings within a constricted site
  • Reduce excavation or dewatering efforts

Technical Details

Typical pile-supported tall/heavy structures require large and thick pile caps to connect the upper structure to the foundation. In the past, large bored piles, caissons, shafts, or barrettes have been used to reduce such a connection. This, however, increases a project schedule. A relatively new technique originally developed in Florida, TBEs are a faster and more cost-effective installation alternative.

Similar to other foundation elements, they interact with the soil through the surrounding surface friction and end-bearing capacities to transfer the upper structure loads to the soil. TBEs produce the same overarching perimeter and bottom areas as the alternatives, resulting in a reduction in the size and depth of pile caps. As proven in Florida, because the connection between the column and element (pile cap) is thinner, the cost of excavation and dewatering decreases.
