Diaphragm Walls

A diaphragm wall is a reinforced concrete wall that is used to support the deep excavations in large infrastructure projects. The D walls are constructed in panels of length approximately 5m each. The excavation is carried out with the help of a hydraulic grab followed by the lowering of the cage. The stability of the excavated trench is maintained by polymer or bentonite.

Purpose / Necessity of Diaphragm Walls:

  • Commonly used in congested urban areas for deep excavations
  • Can be constructed in the close of the proximity of existing structures
  • In Top-Down Constructions where Diaphragm walls can become part of the structure for underground parking facilities.
  • In the cut – a cover method for tunnel construction.
  • Designable to carry vertical loads
  • Less noise and vibration during installation

INDIANA BUILD INFRASTRUCTURE has successfully constructed projects from 400 mm – 1000 mm thickness upto 30 m depth.
