Contiguous Pile Wall
Contiguous Pile Wall
A contiguous pile wall consists of closely spaced reinforced concrete piles installed with small gaps between adjacent piles to form a retaining structure.
Typical Applications
Basement retention
Excavation support
Temporary retaining walls
Advantages
Lower cost than secant walls
Reduced vibration
Suitable in stable ground
Limitations
Not watertight
Ground loss possible between piles
Less suitable below groundwater

Install reinforcement cages
Cast piles
Repeat intermediate piles
Excavate in stages
Install temporary support if required
