ADVANTAGES of Using NO-DIG® Microtunneling and
Small Diameter Tunneling Methods for Pipe Installation

Sewers WITHOUT Trenches-
The New Breed of Microtunneling!

• Minimizes disruption to existing utilities and services during construction.
• Virtually a maintenance free construction.
• Network design flexibility. Provides a cost effective alternative to open cut construction.
• Faster construction, especially in highly urbanized environments.
• Considerably reduces the amount of excavated material to be stacked/removed compared to an open cut excavation method because only the pipe bore, not an open trench, is excavated.
• When working in contaminated soils, the only material excavated is that of the pipe bore, and it is removed with slurry.
• Avoids the need to de-water the pipe trench, thereby significantly reducing the risk of collapse/settlement to surrounding structures/roads, compared to open trench installation methods.
• Reduces the need for man-entry and improves operator/worker safety because of remote control capability.
• Minimizes restoration costs to road surfaces after construction.

• Accurate line and grade installation with tolerances of +/- one inch (1").
• Strength of jacking pipe is typically greater than that of open cut pipe.
• Smooth internal finish gives good flow characteristics.
• No carrier pipe required; carrier pipe is installed directly behind the tunneling machine.
• Prevention of ground water intrusion by use of pipes with sealed flexible joints.
