Ground improvement techniques are used when soils are not capable of supporting proposed structures. These methods improve the ground in three ways to varying degrees: increase strength, increase stiffness, and reduce compressibility. This course provides an introduction to ground improvement technologies and an in-depth review of aggregate piers, their design, installation, and benefits.

Upon completion of this course, the Learner should be able to:

• List and describe methods of ground improvement and their objectives.
• Describe the method by which an aggregate pier reinforces the soil in a treatment area.
• Describe the type of support provided by an aggregate pier and some specific applications.
• Discuss pre-design considerations including required information and settlement.
