What Dillon does

E. Dillon & Company, operating as Dillon, is a privately held, vertically integrated industrial minerals company founded in 1868 in Virginia and headquartered at a 700-acre site in Swords Creek, Virginia overlooking the Clinch River. The company operates its own dolomitic limestone quarry and mills, producing a diversified portfolio of mineral sands and powders, aggregates, concrete masonry units, and engineered concrete products across four end markets: Industrial & Manufacturing (DOLO-GLASS for float glass, DOLO-KRETE for concrete, DOLO-FIBER for fiberglass, DOLO-FIL for industrial fillers, DOLO-KOTE for brick, DOLO-STEEL for steelmaking), Agricultural Minerals (agricultural lime, fertilizer fillers, DOLO-TREAT for water purification, DOLO-FEED and DOLO-GEST for livestock), Commercial/Residential/Highway Construction (asphalt and concrete aggregates, Premier Line architectural CMUs, EverLoc retaining walls, DOLO-SCAPE landscaping stones), and Underground Mining (low-silica mine safety dust, MINE-SAFER interlocking blocks, CRIBPAC and CRIBSTAC roof support systems, Micon Blocks, reinforced concrete cribs).

Dillon monetizes its mineral reserves through one-time sale of bulk and bagged mineral products, with pricing quoted per order under net 30-day payment terms and sales led by five dedicated segment sales managers. Distribution is executed via the company's own trucking fleet, rail cars, and common carrier flatbed/dump trucks, supplemented by an online customer portal at portal.fast-weigh.com. Notable proprietary technologies include four patented product systems — EverLoc segmental retaining walls, MINE-SAFER 360-degree interlocking mine stoppings (NIOSH-tested to 90 tons), CRIBPAC fiber-reinforced donut cribs (450 tons), and CRIBSTAC rectangular crib stacks (800 tons) — plus 12+ registered trademarks across the DOLO product family. The Board includes multiple Dillon family members, indicating multi-generational family stewardship, and operational leadership is held by President & COO Kevin Dietrick and CFO Janet Shrader.
