Techniques

Jet grouting improves soil by injecting cement with high pressure and grout with soil to make cement columns in underground.

In grouting, grout is filled in the gaps to strengthen ground stability and increase soil impermeability. 

By using 3D boring, one can improve soil from afar, without demolishing any existing structures. 

Ground freezing provides strongest strengths and impermeability among the soil improving techniques using frozen soil.

A ground anchor aims to stabilize slopes, retaining walls, and structures.

Soil remediation is to restore environment and to prevent others from influenced by the contaminants.
