About This Course

This course examines the importance of understanding soil properties and soil types prior to undertaking a new build or addition to an existing property. It explains how soil is investigated and tested.

Delve into fundamental soil characteristics, starting with a foundational understanding of what constitutes soil and the critical measurements that define its behavior. Progress through various investigative techniques, from hands-on field testing to sophisticated laboratory analysis.

Key learning outcomes include:

  • Understanding the basic properties of soil, including water content, void ratio, specific gravity, and unit weight.
  • Mastering field investigation methods, such as test pits, hand augers, Standard Penetration Tests (SPT), and Cone Penetration Tests (CPT), for in-situ soil analysis.
  • Gaining proficiency in laboratory testing, including sieve analysis for particle size distribution, and Atterberg limits for fine-grained soil classification.
  • Interpreting soil strength parameters through triaxial and direct shear tests, crucial for predicting soil performance under stress.
  • Comprehending the significance of compaction and moisture content in achieving optimal soil density and strength.

Whether you're looking to refresh your collegiate knowledge or seeking practical insights into soil mechanics for engineering applications, this course provides a clear, concise, and engaging exploration of how to effectively identify soil types. Prevent costly project errors and enhance your design capabilities by understanding the very ground you build upon.
