Microtunneling
For nearly three decades, BRH-Garver has enjoyed the challenge of installing microtunneling projects of all sizes and soil conditions throughout the United States. Since our first microtunnel project in 1986, BRH-Garver has continually performed microtunnel work, making us the most experienced microtunnel contractor in North America. BRH-Garver leads the development of the industry by the introduction of new microtunneling technologies of slurry microtunneling in the early 1990´s, pilot tube microtunneling in 2000, and with the first public works installation of PVC sewer pipe using vacuum microtunneling in 2009.
Microtunneling technology creates distinct advantages:
- Reduces surface disruption, i.e. Traffic flow, utility disturbance, pavement removal
- Allows deep installation under existing utilities
- Avoids interruption of high cost fiber optic lines and hi-pressure gas lines
- Able to penetrate through high ground-water tables without dewatering
- Able to penetrate through contaminated soils
- Cost effective when considering alternate costs of disruption
