Tri-State Civil Construction, LLC (TSCC)

Complex ground conditions require more than construction—they require expertise.

Tri-State Civil Construction is a specialty contractor focused on geotechnical construction solutions for demanding civil, infrastructure, and commercial projects. We specialize in deep foundations, support of excavation, dewatering, groundwater treatment, and specialty foundation systems, bringing engineering insight and construction execution together under one team.

Our experience spans highly constrained urban sites, infrastructure upgrades, transportation projects, utility work, and technically complex foundation scopes where precision, safety, and reliability matter most.

Clients rely on Tri-State because we understand that success is built below the surface. We approach every project with a practical, solutions-focused mindset that reduces risk, improves constructability, and helps keep schedules moving.

Built on expertise. Driven by execution.

2017: Foundation

Tri-State Groundwater Solutions was established in Paterson, New Jersey, operating from a modest rented office and yard.

That same year, the company secured its first major dewatering project at the Jacob K. Javits Convention Center expansion—setting the stage for future work on high-profile infrastructure projects including LaGuardia Airport and developments across the New York metropolitan area.

2018: Expanding Capabilities

The acquisition of a brand new Watson EX-90 drill rig marked a key step forward, enabling deep well installations and allowing the company to take on larger scale dewatering projects.

2020: Diversification

Tri-State reached a major milestone by completing its first large-scale grouting project for Metro-North Railroad in Port Chester, expanding its service offerings beyond dewatering.

2021: Strategic Growth

The company relocated its headquarters to Glen Rock, New Jersey, supporting continued expansion.

Significant investments in drilling equipment allowed entry into the micropile installation market, leading to projects with agencies such as New Jersey Transit, Port Authority, NYC DEP, MTA, NYS DOT and many other agencies.

2022: Evolution

Reflecting its expanded capabilities, the company rebranded as Tri-State Civil Construction (TSCC).

TSCC contributed to major developments at John F. Kennedy International Airport and played a role in the transformative East Side Access initiative.

The pile division continued to grow with successful transit and infrastructure projects throughout the region.

2023: Major Investment

TSCC purchased a 3.7-acre property in Mahwah, New Jersey for a new headquarters, shop, and yard—marking a significant long-term investment in the company’s future.

The fleet expanded with larger drilling equipment, and TSCC secured a major contract on the Van Wyck Expressway, performing drilled shafts, micropiles, and large-scale dewatering operations.

2024: Geographic Expansion

TSCC expanded beyond its core region with a major dewatering project inside the Howard Street Tunnel in Baltimore, MD in partnership with Skanska-Fay JV.

This project marked a key step in broadening the company’s geographic reach and reinforcing its ability to deliver on complex infrastructure work.

2025: Strategic Expansion

TSCC expanded its geotechnical capabilities through the acquisition of Shore Systems Group, based in Clarksburg, New Jersey. This strategic move strengthens our presence in the Mid-Atlantic region and extends our service coverage across South Jersey, Delaware, Pennsylvania, and surrounding areas. The acquisition enhances our geotechnical division, broadening our expertise, resources, and capacity to support a wider range of projects while continuing to deliver high-quality solutions to our clients.

2026: Geographic Expansion

TSCC expanded its dewatering operations into the southern United States through the acquisition of Allstate Dewatering, based in Houston, Texas. This strategic investment strengthens our ability to serve clients across new markets and enhances our dewatering capabilities with additional expertise, resources, and regional presence. The expansion marks a significant step in TSCC’s continued growth and commitment to delivering specialized groundwater control solutions nationwide.
