Quality Aggregates

Successful construction projects start with the right foundation. That’s why JML Quarries produces consistent, high-quality aggregates. With onsite testing laboratories and a fleet of trucks ready to serve delivery needs, our quarries produce top quality, state approved construction aggregate. Through two separate operations at our facility in Masten Lake, NY, we process quality sand and gravel and greywacke sandstone ledge rock.

Though we’ve updated our technology, we still use the same gravel plant that has been in operation since 1938

Sand & Gravel

Durable sand and gravel aggregates are an integral part of many construction projects.

Greywacke Ledge Stone

Strong and resistant to weathering, Greywacke is often used as aggregate for building structures or paving roads.
