We are excited to announce the continued development of our Trenchless Resource Documents page. This resource is managed and overseen by the ISTT Technology and Education Committee, whose members are committed to continuously improving these documents and the Trenchless Technology Charts to ensure they effectively meet the needs of the global industry.
1. Historical Archive: "Old Guidelines"
We have added a dedicated section to display our Old Guidelines (2009). While these have been superseded by the updated Trenchless Technology Charts and Descriptions on our website, they remain available for those who require them for historical reference.
Note: As these files are legacy, some internal links may no longer be active. Please use this information with the understanding that some content may be outdated.
2. Updated: Trenchless Technologies Excel Chart
We have been offering an Excel version of the Trenchless Technologies Chart for users who wish to integrate this data into their own materials. We are consistently updating our interactive version of the chart page with new content, and the downloadable Excel version is regularly updated to include these additions.
Recent updates to the chart include:
- Manhole Rehabilitation: A newly added technology providing a comprehensive overview of rehabilitation methods.
- Potholing & Direct Steerable Pipe Thrusting (DSPT): These pages have been revised to provide better clarity, update illustrations, and include additional explanations to reflect recent industry developments.

We invite all industry professionals to utilize these added resources as we continue our commitment to advancing trenchless education and technical excellence worldwide.
