About Us

In the United States, Vertical Access has pioneered industrial roped access techniques derived from rock climbing and caving activities. Employing these methods for over 15 years, Vertical Access has inspected numerous historically significant buildings constructed of a wide variety of materials, including brick and stone masonry, terra cotta, concrete, and cast iron.

Responding to a need for highly specialized inspections in extreme locations, Kent Diebolt, President of Vertical Access LLC founded the company in 1992. Vertical Access has established itself in the fields of Architecture and Engineering, and has distinguished itself in Historic Preservation.
