Gillespie Precast

What Gillespie Precast does

Gillespie Precast is a fifth-generation, family-owned manufacturer of custom precast concrete products serving infrastructure, utility, data center, and construction customers across the Mid-Atlantic United States. The company was established in 1922 as Gillespie and Son, Inc. (a ready-mix concrete business) and restructured in 2004 as a separate precast-focused division. It currently operates four National Precast Concrete Association (NPCA) Certified Plants — two in Chestertown, Maryland (headquarters), one in Greenwood, Delaware, and one in Asheboro, North Carolina (grand opening May 8, 2026) — and serves nine states including Maryland, Delaware, Virginia, Washington D.C., West Virginia, New Jersey, Pennsylvania, North Carolina, and South Carolina. The product portfolio includes box culverts, utility vaults, water meter vaults, sand filters, pump stations, manholes (up to 96-inch flow channels), catch basins, curb inlets, trench drains, septic tanks, custom walls, parking bumpers, and frames/grates/covers, with a sister company Delmarva Castings & Supply providing complementary casting products.

The business model is built on custom-engineered, project-based one-time sales of precast concrete structures to contractors, municipalities, developers, and major data center operators. Pricing is quote-based and project-specific rather than published, with an in-house engineering team providing value-engineered redesigns as a core differentiator. Go-to-market is enterprise field sales, executed by regional sales managers, sales engineers, and a business development director covering defined territories, supported by a direct logistics fleet for job-site delivery. Notable customers include Amazon, Microsoft, QTS, STACK, and Digital Realty (data center utility vaults), Maryland Aviation Administration (BWI Airport expansion), Topgolf Baltimore, Prince George's County Public Schools (StormPod system), and Martin Marietta (quarry infrastructure). The company holds pre-approvals with multiple state DOTs and utilities, has achieved 100% NPCA Annual Inspection scores for multiple consecutive years (ranking in the Top 25 nationally), and has won NPCA Quality Merit Awards and a Creative Use of Precast Award. Management is family-led, with over 200 years of combined industry experience across the leadership team and approximately 150-250 total employees.

Scale indicators5 records

Recent moves14 records

Expansion highlights5 records

Broad incumbents

• Oldcastle Infrastructure (CRH): Largest North American precast concrete manufacturer and a division of CRH plc. Offers overlapping product lines including box culverts, manholes, utility vaults, and stormwater systems, but as part of a national, multi-vertical building products portfolio rather than a focused regional specialist like Gillespie.
• Forterra: Public US precast concrete products manufacturer (formerly LBO of Heidelberg Materials' US precast business) producing pipe, manholes, drainage structures, and specialty precast. Directly comparable product portfolio to Gillespie with national scale advantages; competes for similar DOT and municipal infrastructure bids.

Direct peers

• Jensen Precast: Privately held precast manufacturer specializing in utility structures, manholes, box culverts, septic tanks, and stormwater products with multi-state Western and Mid-Atlantic presence. Closely comparable in product mix, custom-engineering orientation, and customer-base overlap with municipal and utility buyers.
• Tindall Corporation: Privately held US precast/prestressed concrete manufacturer producing structural and architectural precast for infrastructure, parking, utility, and data center projects. Comparable in custom-engineered approach and multi-plant regional operating model.
• Mack Industries: Family-owned, multi-state precast concrete producer of utility structures, manholes, box culverts, and septic systems serving the Midwest and Mid-Atlantic. Closely comparable in family-ownership profile, regional multi-plant model, custom precast engineering, and municipal/contractor customer focus.
• Lindsay Precast: Regional precast manufacturer focused on utility vaults, manholes, and specialty concrete structures primarily in the Northeast and Mid-Atlantic. Highly comparable in product mix and DOT-approval-driven go-to-market strategy.

Regional players

• Conewago Precast: Pennsylvania-based regional precast producer serving Mid-Atlantic infrastructure, utility, and commercial construction markets. Comparable product range and regional customer base competing for some of the same Pennsylvania and Maryland DOT bids as Gillespie.
• Wieser Concrete Products: Family-owned regional precast concrete manufacturer in the upper Midwest producing septic tanks, manholes, and specialty precast structures. Comparable as a multi-generational, family-operated regional precaster with custom engineering capabilities and similar product categories.
