Secant and Tangent Pile Walls Consulting -  NYC, Manhattan, The Boroughs, Nassau County, Suffolk County, Long Island, and New Jersey - Kagaoan Engineering

Secant means overlapping and tangent means next to or adjacent to each other. These wall pilings are similar, but tangent piles are a form of secant walls. Tangent walls use piles that construction crews line up next to each other. These walls are not as watertight as secant piles, but both shoring designs hold back soil, heavy loads, and groundwater. Secant walls overlap by several centimeters and require primary and secondary pile placement.

Secant or tangent pile walls go in the ground through a drilling or boring process using steel beams for support. They may form sheet piling walls with wood, metal, or concrete. These walls can be thin compared to the circular design of secant and tangent piles. The piles offer more stability when holding back large loads.

Just like secant piles, tangent piles are quieter to install when you compare them to sheet piling methods. These walls provide structure for excavation sites near existing buildings. Many construction teams prefer to use these wall types in urban areas where buildings are close to each other. 

Secant walls overlap. Placing these piles means using a softer concrete mix to allow for drilling of overlapping piles. Then a final cast of hard concrete can set the wall creating a watertight structure. Tangent walls sit directly next to each other. Construction crews use hard, durable materials to set the pilings. Usually, workers place steel I-beams to reinforce these pilings and keep them from moving. 

Tangent piles are easier and more affordable to place than secant walls. These walls often go in place faster helping construction crews who are on a tight budget. Tangent walls can be stronger than secant piling designs when using lateral supports in their construction. Both wall types offer support for nearby structures and buildings that may settle or move with vibration and excavation. 

These walls are primarily useful for areas where holding back a lot of earth is important. For example, a business erecting a new building on a lot near heavy structures like a bridge or skyscraper need these walls to stabilize the construction area. These supports keep the ground from dramatically moving during excavation to help sustain the construction area and give strength to the surrounding soil pack.
