Tunnel Construction

Triad Engineering executes complex tunnel projects ranging from 6 to 15 feet in diameter across diverse geological conditions. Our capabilities include tunnel boring machines, roadheaders, and manual excavation methods for projects up to three miles long. We implement advanced shoring systems and install permanent linings using ribs and lagging or poured concrete to ensure structural integrity and longevity.

Sewer Installation

We specialize in deep open-cut sewer installations in urban environments, handling pipe diameters from 6 to 72 inches at depths exceeding 26 feet. Our process includes geotechnical evaluation, utility coordination, and dewatering solutions while maintaining safety protocols in congested areas. The team manages complete sewer system implementation from initial design to final grouting and backfill operations.

Pressure Piping

Triad installs steel, ductile iron, and HDPE pressure piping systems for water, wastewater, and gas transmission. Our expertise includes distribution mains, hydrant connections, and large-diameter transmission lines up to 48 inches. We address challenging urban conditions through precise alignment planning and adaptive construction techniques while ensuring compliance with utility regulations and safety standards.

Pump Station Development

We design and construct pump stations with complete electrical and control systems integration. Our services include temporary pumping solutions during replacement projects and installation of package pump stations for EPA-compliant sewage transport. The team handles structural concrete work, mechanical system integration, and control panel programming to ensure reliable operation in critical infrastructure applications.

Horizontal Directional Drilling

Our HDD division installs underground utilities up to 24 inches in diameter across the southeastern United States. We handle fiber optic, sewer, water, and force main installations using precision guidance systems. This minimally invasive method reduces surface disruption while maintaining installation accuracy for utility crossings beneath roads, waterways, and developed areas.
