Please read before using any results from this site.
The tools on Geotechnical Toolbox are provided for reference, educational, and preliminary screening purposes. They are not a substitute for a formal geotechnical investigation, site-specific analysis, or the professional judgment of a licensed engineer.
Geotechnical engineering deals with materials whose properties vary significantly with location, depth, and conditions. Any result produced by these tools must be independently reviewed and verified by a qualified, licensed Professional Engineer (P.Eng. / PE) before being applied to any project.
- Site investigation data, borehole logs, and laboratory test results always take precedence.
- Applicable building codes and local design standards must be followed.
- Appropriate factors of safety or resistance factors must be selected based on project-specific conditions and applicable codes (NBC, IBC, AASHTO, CSA, Eurocode 7, etc.).
This software is provided "as is", without warranty of any kind. While reasonable care has been taken in implementing the published methods and equations referenced by each tool, no guarantee is made as to the accuracy, completeness, or fitness for any particular purpose.
