Box Culverts

Gillespie Precast manufactures four-sided and three-sided box culverts. They can be manufactured in a wide range of sizes and configurations and are incredibly versatile.

They efficiently channel stormwater, prevent floodwater, and also can serve as short-span bridges and access ways such as pedestrian and utility tunnels.

Constructed from precast concrete, they are designed to withstand significant loads and harsh environment conditions, ensuring long-term performance.

The History of the gillespie businesses

In 1922, George Edward Gillespie laid the foundation for what would become a lasting family legacy creating concrete blocks for a milk house on his small Sudlersville farm. Recognizing a growing need in the community, he brought his son Victor into the business, and together they established Gillespie & Son, Inc, moving operations to Chestertown, MD. As demand continued that vision has grown into a trusted family of companies five generations strong—Gillespie & Son, Inc, DCS and Gillespie Precast LLC—serving the Mid-Atlantic with unmatched quality in ready-mix and precast concrete. With three NPCA-certified plants and a century of craftsmanship behind them, the Gillespie family continues to lead with heart. Every product is manufactured with care, every delivery is on time, and every customer and employee is treated like family—because to the Gillespie's, they are.
