In 2004 Cedar Mountain Stone opened the Gainesville facility in Northern Virginia. The Gainesville yard is a rail served stone distribution center offering a full line of approved construction aggregate.

Dalrymple Companies

The Dalrymple Companies are involved in two related lines of business: heavy/highway construction, and construction materials, which includes crushed stone aggregates and the manufactured products of hot mix asphalt. The companies are currently being managed by the fourth generation of the Dalrymple family. The original business, a gravel supply operation, started in Elmira, NY, in 1902. In those days gravel was shoveled by hand and delivered to customers by horse-drawn wagon.

In 1936, Dalrymple Gravel & Contracting, the original company, was incorporated and a concrete plant was erected to serve the Elmira area. The company was one of the first in New York State to provide customers with ready-mix concrete delivered to the job site by truck.

Following World War II and through the 1950’s, the construction business dramatically expanded, and the company construction division grew into a multi-state operation that offered a wide variety of civil construction services. Today Chemung Contracting Corp., the construction company in the group, completes major highway, bridge, airport, and dam projects throughout the Mid-Atlantic region.

The construction materials companies include the following wholly owned subsidiaries: Seneca Stone Corp., which serves the Seneca Falls area in Upstate New York; and Cedar Mountain Stone which serves the Culpeper and Central Virginia market. These companies mine, crush and sell state-approved aggregates. They also manufacture hot mix asphalt at each stone source location and at numerous distribution points associated with each main plant.

The Dalrymple Companies have supplied quality rock products and hot mix asphalt to the construction industry for over a century. Our companies, Cedar Mountain Stone, and Seneca Stone Corp., are suppliers of these rock and asphalt products. Our construction company, Chemung Contracting Corporation, provides heavy and highway construction services throughout the Mid-Atlantic region.
