• Diaphragm Wall is generally reinforced concrete wall constructed in the ground using Under slurry technique which was developed in Europe.
  • The technique involves excavating a narrow trench that is kept full of an engineered fluid of slurry.
  • Walls of thickness between 300 and 1200 mm can be formed in this way up to a depths of 45 meters.
  • Commonly used in congested areas.
  • Can be Installed in close proximity to existing structure.
  • Practically suited for deep basements.
  • Used in conjunction with “Top Down” construction technique.
  • Can be Installed to considerable depth.
  • Formation of walls with substantial thickness.
  • Flexible system in plan layout.
  • Easily incorporated into Permanent works.
  • Designable to carry vertical loads.
  • Construction time of Basement can be lowered considerably.
  • Economic and Positive solution for large deep basement in saturated and unstable soil profiles.
  • Can be used for seepage control in Dams.
  • Noise levels limited to engine noise only.
  • No vibration during installation.
  • Not economical for small, shallow Basements.
  1. In Situ Cement Bentonite Vertical Wall.
  2. In Situ RCC Vertical Wall.
  3. Precast RCC Vertical Wall.
  4. In Situ Cement Bentonite Vertical Wall
    • Provides water tight barrier.
    • Used to prevent seepage/water loss from Natural reservoir and Dams.
  5. In Situ RCC Vertical Wall
    • Underground Structural element like Metro railway Projects, Basements.
    • Used for Retention systems and Permanent foundation walls.
    • Deep groundwater barriers.
  6. Trenching Equipments
    • Hydraulic Grab.
    • Kelly-mounted or Cable-hung cam buckets.
    • Mechanical Grab.
