Secant Pile – Prime Pile Foundation
What Are Secant Piles?
Secant Piles are overlapping cast-in-situ concrete piles that form a continuous, watertight retaining wall. They are built by constructing primary (soft) piles first, followed by secondary (hard) piles that cut into or “secant” the primary piles. This creates a strong, sealed structure ideal for deep excavations and areas with high groundwater.
Why Choose Secant Piles?
At Prime Pile Foundation, we execute Secant Pile Walls using precise drilling technology and high-quality materials to deliver:
- »Watertight Retaining Walls – The overlapping design significantly reduces groundwater inflow.
- »Superior Structural Strength– Hard–soft or hard–hard pile combinations offer excellent lateral load resistance.
- »Ideal for Dense Urban Areas – Low vibration and minimal disturbance to adjacent buildings.
- »Highly Customizable – Pile diameters, overlap depth, and reinforcement can be tailored to soil conditions.
- »Effective in Challenging Soils – Performs exceptionally well in loose, soft, and waterlogged ground.
Our Execution Process
At Prime Pile Foundation, we use advanced machinery and strict quality control to deliver piles that offer:
- »Site Assessment & Design – Soil investigation to determine wall alignment, pile type, and overlap requirements.
- »Primary Pile Construction – Soft or unreinforced concrete piles drilled at fixed spacing.
- »Secondary Pile Construction – Reinforced hard piles drilled between primary piles—cutting into them to form overlap.
- »Reinforcement & Concreting – High-grade concrete placed using tremie methods for accuracy.
- »Finished Wall Preparation – Additional supports like ground anchors, struts, or shotcrete applied as needed.
Advantages
- »Provides high structural stability and water control
- »Suitable for deep excavations in dense city areas
- »Low noise and vibration
- »Can be designed as temporary or permanent retaining wall
- »Performs well in difficult subsoil conditions
