Secant Pile Walls
Secant Pile Walls consist of a series of overlapped cast-in-place concrete cylinders that form a continuous wall. The diameter, spacing, depth and structural reinforcement of the cylindrical elements are engineered to meet specific project needs and subsurface site conditions. The walls can be used effectively to simultaneously perform a number of earth retention functions including:
- Temporary or Permanent Earth Support
- Foundation Support
- Groundwater and Seepage Control
In association with its international partners, Helical Drilling has developed the capabilities to install secant pile walls in a broad range of soil conditions with unsurpassed speed, accuracy, minimal disturbance and the ability to achieve tight tolerances at very close proximity to adjacent structures. Our construction process involves drilling and casting each cylindrical element in the secant pile wall configuration in a “single pass” using a cased drilling system, which guarantees tight overlap joints, uniformity, and a high-level quality finish. The modular nature of secant pile wall installation offers the versatility that is required to accommodate complex wall layouts and geometrical configurations.
