Our licensed crews install underground switch gears, transformers, and meter bases while maintaining strict safety protocols. With contracts for Dominion Energy and Berkeley Electric Cooperative, we serve entire towns, neighborhoods, and commercial developments across the Low Country region.
Gas Distribution
Our HDD specialists install natural gas distribution systems using MDPE, HDPE, and steel piping from 1.25 to 12 inches in diameter. We execute complex projects including wetlands bores exceeding 1,400 linear feet and interstate crossings at depths up to 25 feet. These services support both residential and industrial gas infrastructure requirements across South Carolina.
Water & Sewer Installation
We construct water distribution systems with mains up to 24 inches in diameter using HDPE, FPVC, and ductile iron materials. Our capabilities include gravity sewer services and forced main sewer lines for residential and commercial applications. The team handles both small and large diameter installations to meet municipal and private development needs.
