What is Slurry Wall Construction | Process | Full Details

Hello everyone, in this article i am going to explain what is slurry wall. Slurry wall construction procedure, advantages of slurry wall construction, limitation of slurry wall construction,  ppt of slurry wall construction techniques, and etc.

So read the article till the end. Please help us to share this article with your friends when you like this article. Because sharing is caring

What is slurry wall technique?

A slurry wall is a construction technique that is used to construct a reinforced cement concrete wall under the soft ground which is close to open water or with a high groundwater table.

Simply, it is a technique that is used to construct a diaphragm wall under the soft ground with any type of shoring.

The slurry wall is specially used to construct diaphragm wall, foundation, underground floors for the basement, etc. under the soft ground.

History of Slurry wall construction:

Slurry wall is first constructed in Line-1 of underground rapid transit system of Milan Italy.

It is used in the construction of a bathtub that is referred to as an underground foundation area of the world trade center, New York.

It is also used in foundation construction of taipai-101 building that is one of a tallest building in the world.

Purposes of Slurry Wall construction:

Purposes of slurry wall construction are as follows.

  • It is used for the seepage control in the underground construction.
  • It is used for Cut-off curtains.
  • It is used to prevent polluted ground water in construction site.
  • It is used as Gas barriers for landfills.

Advantages of Slurry wall:

  • It can be constructed at a very low cost.
  • Using the slurry wall construction technique we can achieve High productivity of construction.
  • Slurry walls have Very low permeability.
  • Slurry walls provide excellent resistance against polluted groundwater.
  • It can also resist horizontal forces like earthquake forces.
  • In this technique, all the excavated material can be reused which means very little spoil of the material has occurred.

Slurry wall construction process:

The sequences of construction of slurry wall are as follow:

  1. Excavation
  2. Slurry Filling
  3. Placement of Steel Reinforcement
  4. Concreting
slurry wall construction sequence

1. Excavation:

The first step of slurry wall construction is the excavation of trenches for reinforced concrete walls. The clamshell shaped digger or hydro mill trench cutter is used to make a trench and create a form for a reinforced concrete wall.

2. Slurry filling:

The next stage of slurry wall construction is the filling with Slurry in the trench. A trench is filled with a slurry that is a mixture of bentonite and water. The trench is simentensoly filled with slurry while clamshell digging the trench.

Slurry prevents the collapsing of surrounding soil by creating outward pressure. That’s the reason, the slurry is used in the construction of the slurry walls.

3. Placement of Steel Reinforcement:

After the filling of the slurry in the trench, it is necessary to insert the steel reinforcement under the trench to make the reinforced concrete wall.

4. Concreting:

The final stage of slurry wall construction is concreting in the trench. The tremie pipe is used to fill concrete in the trench. Ready-mixed concrete is used in slurry wall construction.

Must ensure that the lower level of the tremie pipe is below the topmost layered of concrete that is prevent the mixture of slurry and concrete.

Slurry is come out due to the filling of concrete. Thus, this slurry can be used for the other slurry wall or it can be restored and used for other purposes.

So, this is the full construction procedure of slurry wall. Now the Limitations of slurry wall

Limitations of Slurry wall Construction:

  • Required heavy machinery for construction of slurry walls like a clamshell digger or hydro mill trench cutter.
  • Required skilled laborers.
  • Required a high concentration on work and some precautions taken under consideration.
  • Required a large area

Frequently Asked Question on Slurry Wall Construction

  1. we manufacture a very effective solidification product for managing water-based waste destined for landfill. likely the most cost-effective solution available today. i welcome the opportunity to discuss, offer samples, etc. in efforts to introduce a new asset to liquid spoils management.


  2. Slurry wall construction is a fascinating technique in civil engineering, and this article sheds light on its various aspects. The use of slurry walls in deep excavation projects and foundation support is commendable. Understanding the process and advancements in slurry wall construction is essential for construction professionals and enthusiasts alike. The ability to provide stability and prevent groundwater seepage makes slurry walls a valuable addition to large-scale construction projects, setting new standards in safety and efficiency.
