Welcome to the Great Lakes Trenchless Association.

“The more that we collaborate, learn, and support each other, the stronger our industry will become and more opportunities will present themselves.”
John F. Hendershot, President

Horizontal directional drilling commonly referred to as HDD is a non-invasive trenchless technology. HDD allows the placement of underground utilities in limited-access, developed or restricted areas. Such areas include highways, freeways, parking lots, landscaped areas, streams and rivers or ravines. Because the method is non-invasive, restoration in these situations is greatly reduced, if not eliminated. This contributes to an environmentally safe project and can lead to project savings and enhanced public acceptance.
