Consolidation Grouting

Consolidation Grouting

In foundation pit engineering, when there are relatively weak soil layers in the site, in order to enhance the stability of the foundation pit support system, control the deformation of the surrounding retaining structure, and create conditions for on-site construction and earthwork excavation, reinforcement of the foundation pit soil is carried out.

Construction Technique

Reinforcement: Deep Soil Mixing (DSM)

Reinforcement: Deep Soil Mixing (DSM)

The principle of Deep Doil Mixing is to improve the strength properties of a weak soil (clay, silt and/or sand) by mixing it with the binder (e.g., cement slurry, bentonite, lime, etc.) to form a solidified mixture of soil and cement with a considerable higher strength and mechanical parameters. It is a very flexible technique adopted mainly to increase bearing capacity, reduce settlement and mitigate liquefaction.

Reinforcement: Jet Grouting (JG)

Reinforcement: Jet Grouting (JG)

Jet Grouting (JG) uses high velocity jet of grout to destroy the soil structure and simultaneously mix cement grout into the in-situ soil to form inclusions.Jet grouting method – is used to improve soil strength parameters and at the same time to create an impervious layer.
