Welcome to the Northwest Chapter of NASTT

The Pacific Northwest Chapter is a richly diverse group of contractors, manufacturers, engineers, consultants, utilities, and public works entities. With a valuable wealth of knowledge, our goal is to promote the utilization of trenchless technologies through education. The PNWNASTT also serves to develop relationships that foster communication of ideas and experiences in order to promote further understanding of the available trenchless construction options. Take a look at our Project Highlights page for photos from projects that focus on the solutions offered by using trenchless technology. Our members are continuing to load new project case histories, product information, and trenchless-related articles and papers to the site in order to improve the accessible knowledge base available online, so check in periodically as we expand our online presence. Please take some time to navigate our site and if you wish to know more about a particular trenchless method or would like to find out more about our organization, do not hesitate to contact any of the PNW Chapter Board Members or use our Business Directory to find information about our current members.
