About
AggregatesÂ
Aggregates—such as sand, gravel, and crushed stone—are produced from quarries and pits throughout Dane County. Limestone is quarried from sedimentary rock formations that have hardened over thousands of years. It is extracted by drilling and blasting, then crushed into various sizes using specialized equipment. This crushed stone is commonly used as a base material for parking lots, streets, and highway construction projects.
Sand and gravel are mined from glacial deposits formed by the movement and melting of glaciers thousands of years ago. These materials can be easily excavated with loaders when they are above the water table, or removed with drag lines when they are below it. Sand and gravel are primarily used to produce high-quality aggregates for concrete and asphalt. Lower-quality sand, known as fill sand, is also used in large quantities for filling, grading, and leveling on construction sites.
Why is Stone, Sand, And Gravel Important?Â
Every road traveled, building constructed, and community developed begins with the essential materials beneath our feet: stone, sand, and gravel. These natural resources are used in nearly every construction project and are critical for producing concrete, asphalt, utilities, and transportation infrastructure.
From schools and hospitals to homes, highways, and commercial buildings, aggregate materials help build the spaces people rely on every day. In fact, more than 2 billion tons of aggregates are produced each year in the United States, making them one of the most important materials used to support growing communities and the infrastructure that keeps our world moving forward.
What Does it Mean For the Community?Â
The stone, sand, and gravel industry plays a vital role in strengthening local communities and supporting long-term growth. These essential materials help build and maintain the roads people travel on, the schools children learn in, the hospitals families depend on, and the infrastructure that keeps communities connected every day. From residential neighborhoods and commercial developments to public utilities and transportation systems, aggregate materials serve as the foundation for the spaces people rely on most. Beyond construction, the industry creates local jobs, supports regional businesses, contributes to economic development, and helps provide the resources needed to build safe, reliable communities that can continue to grow and thrive for future generations.

Mineral Exploration
Mineral exploration helps locate and evaluate natural resources used in construction. It is an important first step in ensuring a reliable supply of quality aggregate materials.
Permitting is the next step in the mining and aggregate production process. It ensures operations meet environmental regulations and allows materials to be responsibly extracted for future construction projects.​​
Once resources are identified, mineral extraction allows stone, sand, and gravel to be safely removed and prepared for production. These materials are essential for supporting construction and development.
After extraction and processing, aggregate materials enter the market to be used in roads, buildings, and infrastructure projects. This step helps keep construction projects moving efficiently.
Once materials are ready, the delivery process ensures aggregates are transported safely and efficiently to job sites. Reliable delivery helps keep construction projects on schedule.
Reclamation is the final step in the process, focused on restoring land once mining operations are complete. It helps ensure natural resources are developed responsibly while protecting the environment for the future.
