Roman Stone Construction

What Roman Stone Construction does

Roman Stone Construction Company is a privately held precast concrete manufacturer founded in 1903 by the Montalbine family and headquartered in Bay Shore, New York. The company engineers and manufactures precast concrete products across five primary application segments: transportation infrastructure (temporary and permanent barriers, precast walls, pavement slabs), electrical transmission and telecom infrastructure (conduit, vaults, light pole bases, cast iron castings), coastal protection and renewable energy (concrete mattresses and rock filter bags licensed from Subsea Protection Systems), data center infrastructure (the patent-pending EZ-KEY duct bank system and vaults), and custom engineered precast solutions for non-standard requirements. Manufacturing is conducted at an NPCA-certified Long Island plant, with mobile precast production capability that brings manufacturing on-site for projects with challenging logistics, and marine delivery is enabled through the C-Shore Logistics partnership along the Eastern Seaboard.

The business operates a quote-based, project-driven sales model targeting enterprise and government buyers including utilities (Con Edison, National Grid, NKT, Ørsted), transportation agencies (NYSDOT, NYC DOT, MTA, Port Authority of NY/NJ), municipal authorities (Battery Park City Authority, NYC DEP, Suffolk County Water Authority), and large marine contractors (DEME Group). Roman Stone holds the sole Con Edison approval for precast conduit and has supplied millions of feet over a 50+ year partnership, alongside NYSDOT, NPCA, and Port Authority certifications that function as meaningful competitive barriers. The company earns revenue through one-time sales of standard inventory items, custom-engineered precast manufactured to specification, licensed-technology products, and logistics/installation services. Recent strategic emphasis is on the EZ-KEY rapid-installation product line targeting hyperscale data centers, sustainable material variants (basalt fiber reinforcement, carbon-negative concrete), and offshore wind energy markets, supported by a new Vice President of Business Development for National Infrastructure Products appointed in September 2025.

Core offering

Roman Stone Construction is a manufacturer of engineered precast concrete products for infrastructure applications including transportation barriers, underground utility vaults and conduit, light pole bases, pavement slabs, coastal protection mattresses, rock filter bags, cast iron products, and the patent-pending EZ-KEY duct bank system. The company designs, engineers, and manufactures products in a controlled NPCA-certified facility in Bay Shore, NY, and delivers them to utilities, transportation departments, contractors, government agencies, data center developers, and offshore wind/renewable energy customers across the Eastern Seaboard. Custom engineered precast solutions and on-site mobile precast production complement the standard product portfolio.

Product overview

Roman Stone Construction is a manufacturer of engineered precast concrete products and infrastructure solutions, founded in 1903 and headquartered in Bay Shore, NY. The product portfolio consists of a unified set of precast concrete offerings organized around five application segments: Transportation Infrastructure (temporary and permanent concrete barriers, precast walls, and Roman Road Systems pavement slabs), Electrical Transmission and Telecom Infrastructure (precise conduit, vaults, light pole bases, and cast iron products), Coastal Protection and Renewable Energy (concrete mattresses and rock filter bags licensed from Subsea Protection Systems), Data Center Infrastructure (EZ-KEY duct banks and vaults), and Custom Engineered Precast (bespoke solutions for non-standard requirements). The portfolio also includes a new patent-pending EZ-KEY product line (duct banks and vaults with alignment cones, shear keys, and zip pins for rapid installation), which is the flagship innovation designed for data centers, airports, and major infrastructure. A mobile precast production service enables on-site manufacturing. Key differentiators include Con Edison sole-source approval for conduit, NYSDOT/NPCA/Port Authority certifications, and licensed technologies from Subsea Protection Systems and LPB. The company has recently added sustainable options including basalt fiber reinforcement (eliminating steel rebar) and carbon-negative concrete mix across the EZ-KEY line.

• Smith-Midland Corporation: Smith-Midland produces Easi-Set/Spancrete-style precast barriers, retaining walls, and utility structures. Comparable to Roman Stone in transportation barriers, walls, and infrastructure precast with a wider East Coast and Midwest presence.
• Jensen Precast: Jensen Precast is a major regional and national precast concrete manufacturer producing utility structures, manholes, vaults, barriers, and custom engineered precast — overlapping head-to-head with Roman Stone's product portfolio across utilities and transportation infrastructure.
• AmeriCast: AmeriCast manufactures precast concrete barriers and specialty infrastructure products for DOTs and contractors. Directly competes with Roman Stone's temporary and permanent barrier lines, including J-J Hooks-style connection systems.
• Concrete Pipe & Precast (CPP): Concrete Pipe & Precast is a Virginia-based manufacturer of precast concrete products including manholes, vaults, and utility structures serving East Coast utility and DOT customers. Compares directly to Roman Stone's vault, conduit, and utility infrastructure offerings.

Broad incumbents

• Oldcastle Infrastructure: Oldcastle Infrastructure (a CRH company) is the largest U.S. precast concrete manufacturer offering utility vaults, manholes, barriers, drainage, and concrete pipe. Directly comparable to Roman Stone's precast product lines but with a national manufacturing footprint and broader product portfolio.

Emerging players

• NPCA Member Precasters (regional): The broader NPCA-certified regional precast concrete ecosystem in the Northeast competes for the same DOT, utility, and data center RFPs as Roman Stone. Many smaller, family-owned precast plants in NY/NJ/CT directly contest municipal and utility awards.

Others

• Subsea Protection Systems (SPS): SPS is the originator/licensor of the Fronded Mattress, Fleximat, and rock filter bag product lines that Roman Stone manufactures under license for the U.S. market. Adjacent rather than competitive — SPS supplies technology while Roman Stone manufactures and delivers.
