Underground Construction

leaderboard2 - default

Underground construction refers to installation of buried utility lines, such as water, sewer, electric, gas, or communication. To reduce surface disruption, trenchless construction continues to gain wider use, especially in urban areas. Trenchless techniques use horizontal-directional-drilling rigs, pneumatic piercing tools, and guided-boring machines, all designed to install utilities with minimal surface disruption.
