Secant Wall Piles
Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) to form structural or cutoff walls. From soil mixing to drilled shafts, Mega Pile Inland draws on its complete suite of techniques to optimize the design and construction of these walls.
- Provide slope stabilization
- Create barriers to groundwater flow
- Support bulkheads
- Support of excavations
The columns are constructed using soil mixing, jet grouting, augercast, or drilled shaft methods. Sequenced construction of the elements helps ensure a tight seal for water cut off. The design can incorporate steel bar or beams for reinforcement. Anchors provide additional lateral support if needed. Secant or tangent pile walls can be constructed in a wide variety of soil conditions, including through cobbles and boulders.
