Secant Piling Services

Secant Piling is a specialized deep foundation and earth-retaining solution widely for deep excavations, basement construction, underground structures, and groundwater cut-off systems. At APCC, secant piling is executed to create continuous, high-strength retaining walls for projects across Dubai, Abu Dhabi, and the wider UAE.

This piling method is particularly effective for projects requiring minimal ground movement, high structural stiffness, and excellent groundwater control, making it ideal for dense urban environments and complex geotechnical conditions.

How Secant Piling Works

Secant piling involves constructing a retaining wall by installing overlapping bored piles in a predetermined sequence to form a continuous barrier.

Primary and Secondary Piles

The process consists of:

• Primary piles: Constructed first using low-strength or unreinforced concrete

• Secondary piles: Installed between and partially cutting into the primary piles using reinforced concrete

This overlapping (secant) arrangement creates a rigid and watertight wall suitable for deep excavations and permanent underground structures.
