Secant Pile Walls Construction Methodology!
Secant pile walls are an extremely effective type of embedded or in-ground retaining wall. They are formed with intersecting piles of concrete forming a continuous structure. Secant walls hold soil and rock back, even in unstable soil conditions, while preventing water flow into the exXcavation area. They provide high lateral strength for embedded foundations with the added advantage of a top-down construction method. This causes much less noise and vibration than other retaining wall options. All this translates into contractors being able to build walls and foundations very close to property lines, also in some cases work without additional construction in front of the excavated face.
This is a cost effective one.
