Grout Retaining Wall

Stage 1: Site Preparation

Access for drilling and grouting equipment is ensured, and any obstacles are removed. The site preparation ensures that the area is ready for the arrival of equipment and materials.

Stage 2: Drilling

Holes are drilled along the planned wall alignment to the required depth using rotary or percussion drilling methods. The spacing of the holes is critical to ensure the formation of a continuous wall. The drilling process must be carefully controlled to ensure proper positioning and depth.

Stage 3: Grouting

Grout is injected into the drilled holes to form a continuous barrier. The grouting process is typically done in stages to ensure proper filling and strength. Controlled flow and pressure are used to ensure uniform grout distribution and adequate filling of voids.

Stage 4: Curing

The grout is allowed to cure and harden to form a solid wall. Proper curing is essential for achieving the desired strength and stability. The curing process is monitored to ensure the grout sets correctly and achieves the required properties.

Stage 5: Excavation

Soil is excavated in front of the grouted wall to the required depth. The grouted wall now acts as a retaining structure, providing support during excavation. The excavation process must be carefully managed to avoid disturbing the integrity of the wall.

Stage 6: Finishing

A protective layer or facing is applied to the grouted wall if necessary. This provides a smoother finish and additional protection. The finishing process involves cleaning the wall surface and preparing it for any additional construction activities.

Stage 7: Quality Control

The wall is inspected for strength, alignment, and impermeability. Non-destructive testing methods such as core sampling or integrity testing may be used to assess the quality of the grouted wall. Ensuring that the wall meets all design and safety standards is essential for the success of the project.
