No-Dig Conference and Exhibition for Trenchless Technology

North American Society For Trenchless Technology

Our mission is to be the premier resource for knowledge and education in trenchless technology.

NASTT is an engineering society of individuals, public organizations and private companies with strong beliefs in the practical, social and environmental benefits of trenchless technology.

No-Dig Show

NASTT’s No-Dig Show is the society’s flagship educational and networking event. The Annual No-Dig Show offers quality, non-commercial technical papers; an exhibition hall; a series of specialized trenchless training courses; plus many entertaining networking events and special industry related awards. NASTT’s No-Dig Show is the largest trenchless technology conference in the world.

Trenchless Marketplace

Since 2001, NASTT’s No-Dig Show has nearly doubled in size, keeping pace with the rapid growth of our industry. Cutting-edge technologies are continually being developed and introduced to the marketplace. Each year brings new products, new services and new players. Projects are continuously pushing the boundaries of what can be achieved with trenchless technologies. Our conference creates a unique opportunity for you to see, hear and interact with leaders in the industry who drive the trenchless marketplace today.

How Will You Benefit?

The overall No-Dig Show program is focused on one objective: helping you maximize your investment in trenchless technologies, services and applications. Owners, utilities and municipalities can immediately benefit! You will learn how to replace/repair and install pipelines with minimal excavation while reducing the impact to your surroundings. You will find that trenchless technology is not only the least disruptive option, but oftentimes is the most cost-effective. The technical sessions and exhibitions are designed to provide you with information you need to make the best possible decisions.
