Jet Grouting Services for Effective Soil Stabilisation
GFWA’s jet grouting expertise is reflected in numerous Australian projects.
Jet Grouting used for tunnel break-ins and breakouts and ground improvement. This method enhances ground strength and stability, ideal for various geotechnical challenges.
Our processes
Stage 1: Site Preparation
The site is cleared, and access points for jet grouting operations are prepared. Any obstacles are removed, and the area around the grouting locations is made accessible for drilling and grouting equipment. The site preparation ensures that the area is ready for the arrival of equipment and materials.
Stage 2: Drilling
Small-diameter holes are drilled to the required depth using rotary or percussion drilling methods. The drilling pattern and depth depend on the soil conditions and the design requirements. The drilling process must be carefully controlled to ensure proper positioning and depth.
Stage 3: Jet Grouting
Grout is injected into the soil at high pressure through rotating jets. The high-pressure jets break up the soil and mix it with the grout to form a solidified mass. The jet grouting process is performed in stages to ensure proper filling and strength.
Stage 4: Monitoring
The jet grouting process is continuously monitored to control flow and pressure. Adjustments are made as needed to achieve optimal grouting results. The monitoring process ensures that the grout is evenly distributed and achieves the required properties.
Stage 5: Curing
The grout is allowed to cure and stabilize the soil. Proper curing is essential to achieve the desired strength and stability. The curing process is monitored to ensure the grout sets correctly and achieves the required properties.
Stage 6: Finishing
Any surface disruptions caused by the grouting process are repaired. The site is restored to its original condition, ensuring that the jet grouting does not adversely affect the appearance or functionality of the existing structure.
Stage 7: Quality Control
Load tests and inspections are conducted to ensure the jet grouted mass has achieved the desired strength and stability. Non-destructive testing methods such as core sampling or integrity testing may be used to assess the quality of the grouting. Ensuring that the jet grouted mass meets all design and safety standards is essential for the success of the project.
