Create Continuous Retaining Support for Deep Excavations
About Secant Pile Walls
Secant pile walls are formed by constructing overlapping bored piles to create a continuous retaining system. They are commonly used where excavation support, ground retention and groundwater control need to work together, particularly on constrained urban sites or projects close to existing structures.
The wall is created through a sequence of primary and secondary piles, with reinforced piles providing structural resistance where required. The exact pile diameter, spacing, overlap, depth and reinforcement depend on excavation depth, ground conditions, groundwater and structural design requirements.
Albitar Foundations provides secant pile wall construction as part of its specialist shoring and ground-engineering capabilities in Lebanon. With experience in piling, drilling, excavation support and dewatering, the company can coordinate secant wall execution with the wider below-ground construction sequence.

FAQs
Secant Pile Wall Questions, Answered Clearly
Secant pile walls are used where excavations require continuous structural support and controlled ground retention. These answers explain how secant walls are constructed, where they are used and how they can be integrated with other excavation-support systems.
What is a secant pile wall?
A secant pile wall is a retaining structure made from a series of overlapping bored piles. The overlap between adjacent piles creates a continuous wall that can support surrounding ground during excavation and, depending on the design and ground conditions, help reduce groundwater inflow.
When are secant pile walls used?
Secant pile walls are often used for deep excavations, basements, infrastructure works and urban projects where excavation is close to neighboring structures or property boundaries. They are especially useful when a continuous retaining wall is required.
How are secant pile walls constructed?
Construction typically starts with a sequence of primary piles, followed by secondary piles drilled between them so that they overlap. Secondary piles may be reinforced depending on structural requirements. Accurate positioning and drilling sequence are important to maintain wall continuity.
Can secant pile walls help control groundwater?
Yes. Because the piles overlap, secant walls can provide a relatively continuous barrier that may help limit groundwater entering an excavation. The degree of water control depends on pile overlap, construction quality, ground conditions and the project design, and additional dewatering may still be required.
Does Albitar Foundations provide secant pile wall services in Lebanon?
Yes. Albitar Foundations provides secant pile wall construction in Lebanon as part of its specialist shoring, piling and ground-engineering services. Secant wall works can be coordinated with excavation, anchoring, dewatering and other below-ground construction activities.
