Ground improvement techniques are used to prepare the ground for new construction projects and to reduce the risk of liquefaction in areas of seismic activity.
Keller was the first company to develop methods and equipment for the successful deep compaction of soil in the 1930s and has continued to develop the equipment and widened its application.
Common soil stabilization techniques include a combination of vibro-compaction with stone, concrete or lime columns as well as soil mixing and injection systems.
These techniques, some of which are shown below, have been used by Keller to improve many thousands of sites around the world.
