With the help of Timberline’s specialised long-handled tools, various utility maintenance, repair and rehabilitation operations can be conducted through a small, precisely controlled excavation process called keyhole technology.
Partnering with the US Department of Energy and the Gas Technology Institute (GTI) since 2000, Timberline has developed tools specifically designed for maintaining and repairing plastic pipe in keyhole situations. The technology not only adds safety and saves time/resources, but also allows utilities and their contractors to cost-effectively expose and perform repair and maintenance work on their underground pipe.
For videos and more there is a keyhole channel on YouTube with videos and more information about the keyhole industry.
