CFA Secant Pile Walls
We ensure your newly constructed structure has adequate support and is water-tight with highly resilient CFA secant pile walls.
Where Strength Meets Design
CFA secant pile walls are constructed with intersecting circular reinforced concrete piles. The secant piles are reinforced with the help of steel beams or rebar using the CFA (Continuous Flight Auger) technique. The reinforced concrete guide wall is constructed at the piling platform level, which helps to develop positional and vertical tolerances for the auger or casing. These pile walls prove to be efficient in groundwater control in various ground conditions.

Our Comprehensive Construction Process
Our local specialists follow this streamlined process to construct secant pile walls:
- Install primary or female piles and allow them to achieve the desired level of strength.
- Allow the piles to cure for 2 to 4 days.
- Construct secondary or male piles in between primary piles by cutting into them.
- Install reinforced male piles when alternate piles are formed.
- Reinforce secondary piles with full-length steel reinforcement cages or steel sections to rock-socket them for extra loading requirements.
Being one of the most experienced piling service providers near you, we are the top choice for your next construction project.

Frequently Asked Questions !
Which types of projects require the construction of secant pile walls?
Various construction projects require the construction of secant pile walls for efficient load-bearing, such as foundations and walls of underground storeys, framed and stand-alone bridgeheads, tunnels, and many others.
What is the difference between female and male piles?
The primary piles or columns are called soft or female piles and are not reinforced. On the other hand, load-bearing, reinforced piles that are drilled to intersect the female piles are known as hard or male piles.
Which elements are installed for the reinforcement of CFA secant pile walls?
To reinforce CFA secant pile walls, H-beams, I-beams, Reber cages, or steel channel sections are usually installed.
What is the diameter of secant piles?
On average, the diameter of secant piles varies from 600mm to 1200mm, and the overlap between primary and secondary piles is usually 8cm.
