Secant Pile wall A Secant Piled Wall is a retaining wall constructed for ground retention prior to excavation. The wall is formed by constructing alternating primary (female) and secondary (male) piles where the secondary piles partially cut into either side of the primary piles in order to form a continuous impervious structure. Secant walls are frequently used to as an alternative to Diaphragm walls where obstructions are anticipated, or in urban basement projects where space is limited. In co

Secant or Tangent Piles. Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) each other to form structural walls that resist lateral pressures and groundwater inflow for bulkhead support, earth retention, groundwater control, or slope stability.
