Ground improvement is the procedure typically defined as using mechanical means to improve poor ground conditions. Ground improvement methods improve the engineering properties of the soil mass which is treated to meet project performance requirements.

Objectives

Common reasons for ground improvement include:

Improve bearing capacity
Increase density
Control settlements and permeability
Mitigate liquefaction
Increase slope stability

Typical Techniques

Typical ground improvement techniques are listed below:

Dynamic Compaction
Jet Grouting
Deep Soil Mixing
Ground Freezing
Lime Stabilization
Prefabricated Vertical Drains (PVDs)
