Secant or tangent piles are columns built (tangent) or overlapping (secant) to form structural or cutoff walls. From soil mixing to drilled shafts, HJ Foundation uses its impressive knowledge of these techniques to design and assemble these walls.

Common Uses

  • Provide slope stabilization
  • Create barriers to groundwater flow
  • Support bulkheads
  • Support excavations

Technical Details

The columns are created using soil mixing, jet grouting, augercast piles, or drilled shafts. Sequenced elemental construction ensures a tight seal for water cut off. The design can include reinforcing steel bars or beams. Anchors laterally issue supplemental support. Secant or tangent pile walls can be raised in many kinds of soil conditions (like cobbles and boulders).
