Grout Systems’ Tangent Pile Walls are an earth retention and shoring system used to construct permanent structural walls or cutoff walls.
Tangent piles, a variation of secant piles, are columns constructed adjacent to each other along the perimeter of an excavation to form a structural or cutoff wall. Typically, the piles in a tangent wall are reinforced with steel bars or beams. Tieback anchors provide additional lateral support, if needed.
Tangent pile walls are used when excavations occur near a heavy loaded structure, or to function as an earth retention system to hold back the earth and carry compressive loading. They can be constructed in a wide variety of soil conditions, including through cobbles and boulders, and are well suited for dense, urban environments.
Advantages of Tangent Pile Walls
- Greater alignment flexibility than secant pile walls
- Easier and quicker construction than secant pile walls
- Resistant to heavy load conditions
- Increased wall stiffness
- Minimizes settlement of adjacent structures
- Relatively low cost of mobilization
