Services
Electric Utility Line Construction
We provide turn-key electric distribution construction for primary/secondary lines, street lighting, and solar connections. Licensed for SC utility work, we serve Dominion Energy and local contractors with precision underground installations using directional drilling techniques to minimize surface disruption while ensuring reliable power infrastructure.
Fiber Optic Installation
Our crews install fiber optic and communication lines for residential, commercial, and military applications. Capable of FTTH/FTTP deployments and backbone fiber loops, we handle duct bank construction at locations including Charleston International Airport and Joint Base Charleston, ensuring high-capacity connectivity with minimal environmental impact through trenchless HDD methods.
Water Main Installation
We construct water distribution systems up to 24-inch diameter using HDPE, FPVC, and ductile iron materials. Our capabilities include main lines and service connections for residential and commercial developments, with specialized expertise in gravity and forced main sewer installations that maintain system integrity and regulatory compliance.
Gas Distribution HDD
We install natural gas distribution lines from 1.25 to 12 inches using horizontal directional drilling. Our HDD solutions for MDPE, HDPE, and steel lines include challenging projects like 1,400-foot wetland bores and 25-foot-depth interstate crossings, ensuring safe, code-compliant gas infrastructure with minimal surface disturbance.
Directional Boring Services
Our HDD services create underground utility pathways without traditional trenching. Using surface-launched drilling rigs, we install pipes and cables along precise trajectories for electric, gas, water, and telecom applications. This method protects surface environments while enabling installations beneath roads, waterways, and sensitive areas across South Carolina.
