Micro tunneling is an advanced remote-controlled digging technique used to construct small tunnels. The highly developed technique allows for an impressive tunneling method that only companies knowledgeable in this practice can efficiently execute.
SECA introduced micro tunneling to North America in 1984, with a crossing of Interstate 95 in Miami.
SECA built the first micro tunneled pipe arch tunnel in the U.S. for the Metro Atlanta Regional Transit Authority.
In 1991, our company constructed the first earth pressure balance TBM (Tunnel Boring Machine) in NYC.
Our most recently completed DC Water ART project is the largest diameter microtunnel installation of Hobas pipe ever attempted!
In the past, our company projects have ranged from small cased crossings of highways and waterways to many 1000’s of feet for new sewer infrastructure.
We can assure our customers that SECA’s staff has experience successfully operating top of the line equipment. Our equipment is built by Iseki (1st in US), Herrenknecht (1st in US), Soltau, RASA, Markham/Okumura, and Wirth.
