Founded in 1990, NASTT represents more than 2,000 members throughout the United States, Canada and Mexico who all promote better and more responsible ways to manage our underground infrastructure.

NASTT’s mission is to advance trenchless technology and to promote its benefits for the public and the natural environment by increasing awareness and knowledge through technical information dissemination, research and development, education and training.

NASTT strives to provide a representative voice for all sectors of the trenchless technology industry.

For over 30 years, the all-volunteer members of NASTT have presented non-commercial information seminars and training about these “green alternative” engineering methods to North American communities.
