Underground Construction

With over two decades of experience, ECI provides comprehensive Tunnel Construction & Tunnel Rehabilitation services. We use advanced tunneling methods, such as Tunnel Boring Machines (TBM) and microtunneling, to build precise underground passageways for transportation, utilities, and water management. Our rehabilitation services include liner removal and replacement, contact grouting, and chemical grouting for structural reinforcement and water control. Whether constructing new tunnels or restoring aging ones, our solutions ensure minimal surface disruption and long-lasting infrastructure.

Shaft Construction & Shaft Rehabilitation are vital to accessing underground areas for construction or utilities. ECI specializes in the design and construction of vertical shafts using methods such as caisson sinking, ground freezing, and conventional excavation. In addition to new construction, we offer comprehensive shaft rehabilitation services, including structural steel replacement, liner removal and replacement, and grouting. Whether for ventilation, water extraction, utility access, or emergency egress, our solutions ensure the long-term functionality and safety of complex underground systems.

Microtunneling is essential for installing pipelines in challenging conditions. ECI specializes in both Slurry Microtunneling and Pilot Tube Auger Boring, offering trenchless solutions for pipelines up to 114 inches in diameter. These techniques ensure precise installation while minimizing environmental disruption and surface impact, making them ideal for urban areas and environmentally sensitive locations where traditional methods are not feasible. With remote-controlled technology and guided accuracy, microtunneling delivers reliable results in complex underground environments.
