Foundations in Expansive Soils

COURSE NO: G08-004
Foundations in Expansive Soils
Course Highlights

This online engineering PDH course will cover the test and design methods that can be used to determine soils with heave potential and how to design foundations that can effectively function in heaving soils. After reading this course the student will have valuable knowledge regarding the use of foundations in expansive soils in various soils types.


Soil heave that is caused by soils with swell potential can be detrimental to various types of foundations. There are several variables that can cause heave which are mainly related to a change in moisture conditions.


This 8 PDH online course is applicable to civil, geotechnical, structural and environmental engineers working in the fields of foundation design, roadway design, and materials testing, as well as anyone that would like to gain more knowledge in geotechnical and structural engineering specialties.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding when heave generally occurs after construction
  • Familiarizing with the common problems with shaft foundations
  • Applying lime treatment for soils with swell potential
  • Determining the approximate percent steel for concrete shafts
  • Understanding the effects of lowering the water table
  • Learning how to use the Thornthwaite Moisture Index (MI)
  • Understanding the effects of the water table on soil heave
  • Understanding the effects of a high cation exchange capacity (CEC)
  • Learning how to determine to use differential heave or mat foundations
  • Understanding the effects of structural damage cause by swelling soil
